CEEZAD deputy director co-authors article on Dengue Fever
The deputy director of the Center of Excellence for Emerging and Zoonotic Animal Diseases (CEEZAD) is corresponding author of a recently published article on Dengue Fever.
The article, for which CEEZAD’s Dr. Jean Paul Gonzalez was lead author, was published in the May 12 edition of the Journal of Fever of SciMedCentral. It looks at a 2011 outbreak of Dengue Fever in Thailand. The article focuses on the genetic variability and diversity of the Dengue virus as a major driver to develop an efficient, worldwide-needed, Dengue virus multivalent vaccine.
CEEZAD, an emeritus Department of Homeland Security Center of Excellence, is based at Kansas State University. It focuses on the study of emerging and zoonotic diseases with an emphasis on improving diagnostic techniques and development of safe, efficacious vaccines.
Dengue Fever, a mosquito-borne tropical viral disease, has been around for centuries, but its spread has accelerated since World War II to the point where it has now been identified in more than 100 nations worldwide. In the article, the authors note that the virus is particularly problematic for researchers due to its extreme genetic diversity. The researchers said they found that cycles within its mosquito vector also play “an important role” in that genetic diversity. Using the epitope predicting method across all four variants, they identified seventeen epitopes exhibiting an amino acid substitution due to a non-synonymous mutation. One of the variants showed two epitope sites in the NS5 gene: one of the methyltransferase domains and the other of the RNA-dependent RNA polymerase domain containing a predicted single amino acid antigenic substitution change in a critical site that could contribute to the generation of antigenic variants.
They concluded that the findings “support our data that DENV-4 potentially exhibits a high rate of genetic diversity within an outbreak, conferring to DENV-4 a high potential for host and environmental adaptability that could potentiate the development of resistance to vaccines and/or antiviral drugs.”

CEEZAD deputy director co-authors paper updating taxonomy of Arenaviridae family
CEEZAD’s deputy director is co-author of a soon-to-be published paper on the taxonomy of a virus that infects rodents, humans and snakes.
The article, titled “Taxonomy of the family Arenaviridae and the order Bunyavirales: update 2018,” was co-written by CEEZAD’s Dr. Jean Paul Gonzalez as a member of the Arenaviridae Study Group of the International Committee on Taxonomy of Viruses. The article has been accepted for publication in an upcoming edition of the Archives of Virology. The article will be available online in the near future.
“This article really changes the taxonomy of these two groups of viruses,” Dr. Gonzalez said.
In 2018 the family Arenaviridae was expanded to include a new genus and five novel species. At the same time the recently established order Bunyavirales was expanded by three species. The article presented the updated taxonomy of both the family and order as now accepted by the International Committee on Taxonomy of Viruses. It also summarizes additional taxonomic proposals that may affect the order in the near future.
In particular, the genus Arenavirus was re-named Mammarenavirus, and a second genus, Reptarenavirus, was established in 2014 for several of the newly discovered snake viruses. A non-Linnean binomial species nomenclature was adopted for the entire family Arenaviridae. Since then, the genus Mammarenavirus has been extended by eight species for novel murid viruses discovered in Africa and Asia.

CEEZAD Conducts Symposium on EHDV
Experts in the fight against one of the leading killers of North American white-tailed deer participated in a CEEZAD-sponsored mini-symposium March 30, designed to gauge progress against the virus responsible for a disease with an extensive impact on the deer farming industry.
The virus, known as Epizootic Hemorrhagic Disease Virus or EHDV, is a significant threat to the American white-tailed deer industry, whose value for the US has been estimated as high as $7.9 billion. EHDV outbreaks have been reported across all but few northern-most sections of the United States.
The symposium, held at the Mara Conference Center in Kansas State University’s College of Veterinary Medicine, involved experts from the industry along with academics and governmental researchers working on development of mitigation strategies including potential vaccines against EHD.
A team led by Dr. Juergen Richt, CEEZAD’s Director and The Regents Distinguished Professor at Kansas State University, organized the conference.

Shawn Schafer, executive director of the North American Deer Farmer Association, delivered a summary of the direct and indirect economic impact of EHDV in the United States. He also asserted that EHDV “affects the agriculture industry altogether,” rather than merely the white-tailed deer industry since cattle, big horn sheep and other wild and domestic ungulates have also been known to become infected.
Historically, Schafer said, major outbreaks sometimes occur in multi-year cycles. He also noted that there has not been a significant outbreak for several years, but added he did not know why that was the case. “Maybe we’re getting better at control, maybe our animals built up their immunity (disease-resistance).” He added, however, that immunities wear off across generations, asking “how long before we’re hit again?” The EHDV is transmitted to deer by culicoides midges, tiny insects that are carried by winds and that feed off an animal’s blood. When they feed, they deliver the virus. In 2015, EHDV virus was isolated from 19 states encompassing five species of deer.
Dr. Samantha Wisely, who oversees the Cervidae Health Research Initiative (CHeRI) in Florida, reported that between 33 and 60 percent of cases her laboratory receives are either EHDV or Bluetongue, a related disease. She added that even when EHDV isn’t the prime mortality factor, it is often contributory.
Dr. David Stallknecht, a professor at the University of Georgia, said the disease (i.e. the culicoides vectors) appears to be taking advantage of a warming climate to spread itself northward. He noted that in the 1980s, the virus’ northern boundary was approximately the 41st parallel, whereas today that boundary is about the 43rd parallel. “When it hits a new spot, it seems to stay…it establishes,” he said. He said drought also appears to be a contributing factor, the virus possibly flourishing during times when host animals are under greater stress and gathering in large group at water wells.
Dr. Barbara Drolet, a research microbiologist at the Manhattan-based Arthropod-Borne Animal Disease Research Unit (ABADRU), described the dynamics of EHDV infection in its vector, Culicoides sonorensis. She could elegantly show that the virus disseminates from the midges to others tissues, and is present by day 5 post feeding in the hemolymph; most likely the midges are able to transmit EHDV five days after an infective blood meal.
Dr. William Wilson, also a research microbiologist with ABADRU, told attendees of progress his lab in collaboration with CEEZAD researchers is making toward development of a vaccine for EHDV. Although vaccines against EHDV have been developed, they are not widely used due to flaws. Wilson said his goal is to develop a vaccine that is safe, easily scalable, and that allows for differentiation between infected and vaccinated animals. He also wants it to be flexible so that “if the strain (of virus) changes, it could be adapted”. He is using baculovirus-expressed subunit vaccines, which showed immunogenicity in mice, cattle and deer and efficacy in deer, and he is close to his goals. One significant remaining step, he said, is for the conduct of duration-of-immunity studies on the ABADRU/KSU vaccine. Schafer said that duration question is a large one for deer farmers and breeders.
The Center of Excellence for Emerging and Zoonotic Animal Diseases (CEEZAD) is a Department of Homeland Security Emeritus Center of Excellence based at Kansas State University dedicated to the study, containment and prevention of emerging and zoonotic transboundary diseases. This symposium was supported through funding received from the Kansas Department of Commerce, formerly the Kansas Bioscience Authority under the Federal Matching Program Grant Agreement. The views and conclusions presented are those of the presenters and should not be interpreted as necessarily representing the official policies, either expressed or implied, of the Kansas Department of Commerce-Kansas Bioscience Authority.

CEEZAD deputy director co-authors paper on history and status of Ebola
CEEZAD’s deputy director is co-author of a recently published paper on recent developments in the effort to contain the Ebola virus.
The article, titled “Revisiting Ebola, a quiet river in the heart of Africa,” was co-written by CEEZAD’s Dr. Jean Paul Gonzalez with Nadia Wauquier of MRI Global in Dakar, Senegal, and Tom Vincent of the O’Neill Institute for National and Global Health Law at Georgetown. It was published in the December 2017 edition of Medecine et Sante Tropicales.
Dr. Gonzalez and his team persistently followed up the natural history of the Ebola Virus from its inception in Central Africa from the Pasteur Institute of Bangui in the Central African Republic, to the late 1970s Ebola Virus Disease emergence and spread in West Africa in 2014.
In the paper’s abstract, the researchers note that Dr. Gonzalez first questioned progress in the effort to contain Ebola more than three decades ago. They conclude that in the intervening period, infrastructure improvements have been made. But they also note that the global reach of the virus has increased, and that broadened presence has not translated into marginal increases in preparedness necessary to slow the virus’s progress. In other words, they express their concern, pointing out that “we do not seem to be learning from our mistakes.” and, the elusive Ebolavirus needs to be tirelessly tracked.

Visiting researcher tackling problem of African horse sickness
African horse sickness is a highly infectious and deadly disease of horses. Although contained for the present to sub-Saharan Africa, its virulence, track record and the ease with it is transmitted makes it a potentially serious threat to the horse population in much of the world. That’s why Dr. James MacLachlan devotes much of his professional energy to combatting it.
Dr. Maclachlan is an emeritus distinguished professor of pathology, microbiology and immunology at the School of Veterinary Medicine at the University of California-Davis. He is also a member of the advisory board of the Center of Excellence for Emerging and Zoonotic Animal Diseases (CEEZAD), and was visiting CEEZAD offices in March as a participant of the EHDV symposium with Dr. Juergen Richt, CEEZAD’s director.
African horse sickness is one of several transboundary diseases that are the focus of Dr. Maclachlan’s research. Although presently restricted to sub-Saharan Africa, scientists do not presume that geographic limitation will continue, particularly since it has previously encroached in Europe and elsewhere. The last outbreak outside Africa was in the Iberian Peninsula (Spain and Portugal) in the 1980s.
Governments and scientists use a system of tight border controls in an effort to prevent African horse sickness from spreading. The problem is those controls only work on the horses themselves; the various species of midges that actually transmit the disease aren’t subjected to border checks. And midges can move great distances when they are carried by wind currents. Compound that with climatic changes that make it easier for midges to serve as disease vectors in a broader geographic range and the challenge becomes obvious.
“Midges are sometimes referred to aerial plankton,” Dr. Maclachlan said. “They ride the wind currents.”
African horse sickness is an old disease, first recognized in the 14th Century in Yemen. Although there Is no cure for an infected horse, a vaccine has been developed and has been used for many decades in the affected areas of Africa. Maclachlan is among scientists and researchers who have worked closely with Merial, a commercial manufacturer, to produce a different vaccine that does not rely on live attenuated virus, meaning it could be used in a crisis elsewhere in the world. Since the vaccine in use in Africa is live attenuated, “we would not use it outside sub-Saharan Africa,” Maclachlan said. The problem with the vaccine under development is marketability: since the disease does not presently exist outside of Africa, manufacturers have little incentive to produce it. “If you make a new generation of vaccine, what are you making it for…who’s going to want it until there is a crisis?” Maclachlan asked.

Two Selected for Orion, CEEZAD Internship Project
Two students have been selected to take part in a Biodefense Internship Program working with Orion Integrated Biosciences and supported by the Center of Excellence for Emerging and Zoonotic Animal Diseases (CEEZAD).
The students are Alice Lam, an engineering student at Kansas State University, and Chester McDowell, a veterinary student in the College of Veterinary Medicine at Kansas State.
Willy Valdivia, CEO of Orion integrated Biosciences, said the internship program will focus on the development of an analytical tool capable of combining different text and data mining tools used in the research of emerging and zoonotic disease threats. The idea is to improve near-real time situational awareness of abnormal and imminent biological threats coupled with risk-based analytics.
“This approach has great potential for advancing the students’ understanding of how to make our vastly expanding knowledge base more readily available to researchers and scientists,” he said.
Lam previously completed an internship involving the development of a classifier that predicts when patients with existing aorta aneurysms should be checked. She said the integration of such fields with computer science has always been a personal passion. “As I experience more of real-life problems, I begin to understand why I enjoy my work so much,” she said. She wants to use this internship to learn more about bio-surveillance and bio-informatics. “This program will help me advance my professional software developer skills and also the background I need for my future career,” she said.

CEEZAD Representative Speaks as Part of Tallgrass Taphouse Series
CEEZAD’s role in fighting transboundary animal diseases was the focus of a recent presentation that was part of the Science on Tap series.
Sabarish Indran, a post-doctoral fellow in the lab of Dr. Juergen Richt, CEEZAD’s director, delivered the presentation to an audience of about 70 people at the Tallgrass Taphouse. The series brings people who are interested in science together weekly for discussions over dinner and drinks. The series is sponsored by Sunset Zoo’s Behind The Science initiative.
Dr. Indran specializes in the study of Rift Valley Fever. In his presentation, however, he focused on the broader topic of transboundary diseases in general. Transboundary diseases are those whose threat extends beyond the borders of any single nation.
He noted that CEEZAD scientists study the causes of disease and the methods by which a disease responds to its host. Central questions concern how movement of a disease can be slowed or prevented, how diseases can be identified and understood, and current movement trends.
He told his audience that three-quarters of all human diseases identified within the past decade were zoonotic in nature, meaning they came from animals.

Life in the Gobi Desert
The search for zoonotic diseases can take researchers from the Center of Excellence for Emerging and Zoonotic Animal Diseases to some exotic locales. Few, however, are likely to be more exotic, or more challenging, than the Gobi Desert of Mongolia.
Dr. Juergen Richt, director of CEEZAD, spent several days there in September as part of a team of veterinary scientists researching the spread of Middle East Respiratory Syndrome (MERS), Rift Valley Fever and various swine diseases. Working with a group that also included Mongolian scientists, their mission was to track the spread of those diseases through the indigenous camel population as well as the wild and domestic pig populations.
The researchers spent most of their time at a site six hours south of Ulaanbaatar, the nation’s capital city, close to the Gobi Desert, where daytime summer temperatures can exceed 120 degrees. There they collected blood samples from about 50 Bactrian camels and about 40 head of cattle in an effort to ascertain the presence of MERS in camels or Rift Valley Fever in camels and cattle.
“The challenge is to find and catch” the camels, Dr. Richt said. “They belong to nomadic farmers.” He said the local veterinarians are able to guide them to the camels.
The second challenge is keeping the samples cool in the hot desert environment before returning to the laboratory.
MERS, a viral respiratory disease, was discovered in Saudi Arabia about five years ago and has since spread to several other countries. It can cause serious complications in humans, and in some cases death. The disease appears to be spread to humans by contact with infected camels. In Mongolia, the research team collected samples from about 50 camels. Those samples suggested the presence of MERS antibodies among the camels, although that suggestion is still being confirmed by additional laboratory testing.
Tests for Rift Valley Fever in camels and cattle were negative.
Additionally, the team spent a day working in a farming area north of Ulaanbaatar in an effort to ascertain whether either Classical Swine Fever (CSFV), Swine Influenza Virus (SIV) or African Swine Fever (ASF) had spread to that region’s pig populations. The potential spread of ASF is of particular concern because the disease, which is often fatal to swine, has spread in recent months from the European portion of Russia into the Asian portion of Russia. Geographically, Mongolia is directly between Russia and China, which has one of the largest populations of pigs in the world. If ASF were to infect the Mongolian population of pigs and then spread through Mongolia to China, the consequences for the world’s food supply could be significant. The testing is still ongoing, although testing for Swine Influenza Virus was negative.
In addition to Dr. Richt, the research team was led by Dr. Batsukh Zayat, of the Institute of Veterinary Medicine in Ulaanbaatar.

CEEZAD Deputy Director Authors Article on Meningococcal Disease in Ukraine
An article co-authored by the deputy director of the Center of Excellence for Emerging and Zoonotic Animal Diseases was recently published by Intech, the world’s largest science, technology and medicine open access book publisher.
Dr. Jean Paul Gonzalez wrote the article, on Meningococcal disease in Ukraine, in association with Hennadi Mokhort and Sergey Kramarev.
Meningococcal disease in Ukraine represents an important cause of mortality mostly among children less than five years old. The study illustrates the advancement in understanding of Meningococcal epidemiology across the national level by using20 years of data provided by the Ministry of Health of Ukraine. This data includes: demography (census); disease incidence from 1973 to 2015; Meningococcal disease mortality; demographic data (sex, age, leaving area/city/village); Comparative etiology of purulent meningitis; serogroups of invasive meningococcal disease; carriers prevalence; a set of clinical data (meningitis, meningococcemia, nasopharyngitis, etc.); and a set of environmental data (season, etc.).
The dynamic of the disease is described for the past 20-year period including incidence, prevalence, spatial distribution, seasonality, and risk factors. Existing state-of-the-art meningococcal infection epidemiology is presented for all of the country. Ultimately, time series analysis of record and spatial distribution over such a long period of time supported the development of original construct of various models encompassing risk and vulnerability, and ways to improve epidemiological surveillance, and develop vaccination strategies in country.
Mokhort is an assistant professor in the Department of Epidemiology at Bogomolets National Medical University in Kiev, Ukraine. Kramarev is affiliated with the Ministry of Health in Kiev, Ukraine.
CEEZAD Director Plays Active Role at World Veterinary Congress
The director of the Center of Excellence for Emerging and Zoonotic Animal Diseases (CEEZAD) played an active role at the 33rd World Veterinary Congress in Incheon, South Korea.
Dr. Jürgen Richt, the Regents Distinguished Professor at Kansas State University, chaired a session on porcine medicine that featured presentations on vaccination, emerging infections, oral fluid sampling and swine enteric coronaviruses. The conference was held Aug. 27-31 at the Incheon Songdo exhibition hall, Incheon, South Korea.
In addition to chairing the session, he gave three 45 minutes presentations as summarized below
During his presentation on CEEZAD, Dr. Richt told participants of its creation in 2010 to help protect the nation’s agricultural and public health sectors against high-consequence foreign animal, emerging and zoonotic disease threats. CEEZAD is headquartered at Kansas State University in Manhattan KS. The university is part of the Kansas City Animal Health Corridor and houses the College of Veterinary Medicine and the Biosecurity Research Institute. It is also adjacent to the site for the Department of Homeland Security’s premier animal research facility, the National Bio and Agro-defense Facility, or NBAF, under construction.
Richt noted that CEEZAD has four principal missions:
- Development of novel, safe, efficacious and DIVA-compatible vaccines - for prevention and control of high-impact emerging and zoonotic diseases - that can be manufactured in the U.S.
- Development and expansion of technologies and platforms for laboratory and point-of-need pathogen detection.
- Development of models to predict high-consequence disease behavior in the U.S. to aid prevention or outbreak control.
- Development of education and training programs for students, veterinarians, first responders and researchers in high-impact animal diseases and animal emergencies.
He told conference attendees that CEEZAD funds scientists specializing in animal health, public health, education, diagnostics, therapy and vaccinology. In this way, CEEZAD is enhancing the resilience of the U.S. pre-harvest agricultural system through investigator-directed research. CEEZAD-funded and coordinated research is conducted at more than 15 U.S. and international universities as well as governmental agencies and industry partners. He also outlined two CEEZAD projects, one on point of need diagnostics, and the other on the development of a recombinant Newcastle disease virus-vectored Highly Pathogenic Avian Influenza (HPAI) vaccine for poultry. The NDV-vectored vaccine, for possible use in future HPAI outbreaks, provides excellent protection in live and inactivated vaccine forms, and via practical mass application.
African Swine Fever Research
During his presentation on CEEZAD’s research into African Swine Fever virus (ASFV), he said the study was designed to evaluate the immune response of pigs to various ASFV antigens including recombinant proteins and cDNA constructs, using a heterologous prime-boost vaccination approach. The ASFV genes encoding the structural proteins p15, p35, p54, CD2v (CD2-like)were synthesized based on the ASFV isolate Georgia/2007 and the respective recombinant proteins were expressed in a baculovirus or E.coli expression system.
The cDNAs were cloned into pcDNA3.1 expression vector and included the p72, p32, CP312R and CD2v genes. Three-week old piglets were used for the immunogenicity study. The vaccination groups consisted of a combination of different recombinant proteins and plasmid DNAs. The piglets were inoculated intramuscularly with 100μg of recombinant protein mixed with ISA25 adjuvant and 100μg of plasmid DNA.
Piglets were inoculated three times at two-week intervals and euthanized one week after the last immunization. Blood collection was carried out on the day of vaccination and at the time of euthanasia. ASFV-specific antibody responses in serum of immunized pigs were evaluated using ELISA, western blot and virus neutralization tests.
The results of ELISA and western blot showed that antibodies were induced against each recombinant protein. In virus neutralization assays, neutralizing activity was found mainly in sera from pigs immunized with structural ASFV proteins; in some cases the neutralizing activity was increased by combination with cDNA plasmids especially cDNA for p72 and CD2v. Pigs immunized three times with ASFV p15, p35 and p54 proteins in combination with cDNA plasmids CD2v, p72 and p32 were selected for challenge with virulent Armenia 2007 virus. Challenge was done in BSL-3Ag biocontainment and 5 age controlled animals served as challenge controls.
Neither the vaccinated nor the mock-vaccinated animals were protected against virulent ASFV challenge. Richt said these results will guide CEEZAD in its efforts to develop a potential vaccine against ASF.
Rift Valley Fever Research
During his presentation on Rift Valley Fever virus (RVFV), he noted that it is a mosquito-borne zoonotic pathogen causing serious morbidity and mortality in livestock and humans in Africa and the Arabian Peninsula. Richt said the virus also has great potential for transboundary spread due to the presence of competent vectors in non-endemic areas. There is currently no fully licensed vaccine suitable for use in livestock or humans outside endemic areas.
He reported on CEEZAD’s evaluation of the efficacy of a recombinant subunit vaccine based on the RVFV Gn and Gc glycoproteins. RVFV structural proteins, amino-terminus glycoprotein Gn and carboxyl-terminus glycoprotein Gc, were expressed using a recombinant baculovirus expression system. The vaccine elicited strong virus neutralizing antibody responses in sheep and was DIVA (differentiating naturally infected from vaccinated animals) compatible.
In a sheep efficacy study, animals were vaccinated subcutaneously with the glycoprotein-based subunit vaccine candidate and then subjected to heterologous challenge with the virulent Kenya-128B-15 RVFV strain. The vaccine elicited high virus neutralizing antibody titers and conferred complete protection in all vaccinated sheep, as evidenced by prevention of viremia, fever and absence of RVFV-associated histopathological lesions. Richt said CEEZAD researchers concluded that the subunit vaccine platform represents a promising strategy for the prevention and control of RVFV infections in susceptible hosts.

The deputy director of the Center of Excellence for Emerging and Zoonotic Animal Diseases outlined the challenges facing efforts to combat viral zoonotic diseases in Africa before a group of health professionals in Kansas City recently.
Dr. Jean Paul Gonzalez spoke to an Aug. 27-28 meeting of One Health Innovations. He focused his talk on biosurveillance strategies for dealing with emerging diseases in Africa. His presentation was based on material prepared jointly by Dr. Gonzalez and by Dr. Juergen Richt, director of CEEZAD.
Dr. Gonzalez outlined three particular challenges and goals for those attempting to thwart the movement of viral zoonotic diseases both into and out of Africa. Those challenges are: to be part of a global framework; the relative absence of early warning systems, lab networks, capacity-building and health systems; and individual national characteristics that can modulate preparedness and response.
Specifically, he underscored the need for early point-of-need detection, involving PCR detection platforms. To that end, he acquainted attendees with ongoing efforts at CEEZAD to perfect and market a portable PCR detection platform capable of producing results within one hour.
He also discussed the need for broader access to a portable RNA and DNA sequencing device improving sample-to-answer times.
Among specific outbreaks discussed by Dr. Gonzalez were:
*The 2014 emergence of Ebola virus in Guinea and Sierra Leone in West Africa. He noted that hundreds of cases presented in those countries and also in the Democratic Republic of Congo, many in regions where times required to reach a health facility were measured in hours rather than minutes.
*The 2015 emergence in Nigeria and subsequent spread of Avian influenza. He noted that the World Health Organization has found that various influenza subtypes continue to be detected in birds in Africa, Europe and Asia, some containing the potential to cause disease in humans.
*The challenges posed by recent outbreaks in Africa of Rift Valley Fever virus, monkeypox, Crimean Congo hemorrhagic fever virus, anthrax and Brucella.
*The potential risk of a pandemic incident involving a disease emerging from Africa, and the need for increased transborder protection measures.

Researcher Undertakes Second Summer of Work on Nanoparticles
It’s been a busy and productive year for a Mississippi Valley State University researcher involved with the Center of Excellence For Emerging and Zoonotic Diseases (CEEZAD).
Dr. Matthewos Eshete, an associate professor of chemistry at Mississippi Valley State, is spending this summer right back where he was last year, working in the lab of Dr. Seong-O Choi and Dr. Santosh Aryal at Kansas State University. He is continuing his researcher into the binding interactions between proteins and biodegradable nanoparticles via a follow-up award to work he was involved with last summer using a Department of Homeland Security grant. CEEZAD sponsored Eshete’s work both summers through its Minority Serving Institution program.
Biodegradable nanoparticles are polymers containing great potential in developing therapeutic molecules such as vaccines and drugs to target cells. A nanoparticle is defined as being between one billionth of a meter and 10 millionths of a meter in size. The study of nanoparticles is playing a major role in the advancement of modern medicine because their interaction with proteins is consequential for drug delivery and the immune system.
Following his experience last summer, Dr. Eshete, who is a chemistry professor at MVSU, returned to his classroom where he was able to apply the lessons learned during that summer work. He also presented findings from his research to the Mississippi Academy of Science in February, and to the 2nd Global Nanotechnology Conference in Las Vegas in December.
“It was a good review,” he said of his published finding, which is titled, “Interaction of Immune System Protein With Pegylated and Unpegylated Polymeric Nanoparticles.” In addition to Dr. Eshete, the co-authors include Kayla Bailey, an MVSU student who joined him during his 2016 summer research, Dr. Choi, Dr. Aryal, and Tuyen Nguyen. It has been accepted for publication in Volume 6 of Advances in Nanoparticles, a peer-reviewed publication.
This summer at KSU, Dr. Eshete is expanding the work he did last summer, trying to test the efficacy of different modifications. The hope is that one or more of the modifications will hone scientists’ abilities to deliver drug to the affected tissue or cell in the body.” At present, one of the limitations of both drug-delivery and vaccinology-related research is the precision with which the affected tissue or cells are targeted.
Dr. Eshete intends to continue his research when he returns to MVSU in the fall. Moreover He has recruited two students to work on the project with him. He hopes that in addition to answering some of the scientific question, the research project will help rekindle students’ interest in science and technology and prepare them for 21st century work force.

CEEZAD Co-Sponsors Conference for Rural Veterinary Practitioners
An inaugural event in Manhattan, Kansas, has helped educate rural veterinarians on how to respond and work together in the event of a potential transboundary emergency situation.
Held June 4 at the Hilton Garden Inn, the Rural Veterinary Practitioner Conference was sponsored by the U.S. Department of Agriculture with collaboration from the Beef Cattle Institute, Center of Excellence for Emerging and Zoonotic Animal Diseases, National Agriculture Biosecurity Center (NABC), College of Veterinary Medicine at Kansas State University and the Kansas Department of Agriculture.
The conference’s theme was “Preparing for Disease Challenges” and featured a variety of speakers such as Dr. Justin Smith, Kansas’ animal health commissioner. He has responsibility for directing the statewide response outbreaks of emerging or transboundary disease(s). He noted that Kansas is particularly vulnerable, in part, due to the annual shipment of more than 4.5 million head of cattle into the state (not counting cattle shipped purely for purposes of slaughter).
Dr. Smith said contingency plans in Kansas are based on the possible outbreak of foot and mouth disease, as it represents a worst-case scenario. He said, “If we can stop that, we can stop anything.”
Dr. Smith explained the first element of such contingency plans is to stop movement of the animal, which is a key element in controlling the spread of any potential outbreak. He emphasized how veterinarians in Kansas would play key roles in the event of any such outbreak since the state’s full-time manpower is sufficient to cope with the needs in an emergency.
Dr. Smith said the state response would involve a permitting process, but added that the state does not want any of its plans to damage the ability of farmers and ranchers to participate in the market.
“We want to make sure we can move product as soon as possible,” Dr. Smith said. “The issue is doing it at the speed of commerce.”
Dr. Ken Burton, director of project coordination for the Biosecurity Research Institute at Kansas State University and program director for the NABC, noted that with about 320,000 viruses capable of infecting mammals, potential concerns are abundant. He pointed out the nation’s agricultural sector is responsible for about 1 in 10 jobs, contributing $835 billion to the nation’s gross domestic product. With that level of activity, Dr. Burton said it’s easy to understand why the job of protecting the nation’s animal food supply from potential transboundary and emerging threats is so vital.
Other Kansas State University animal health experts spoke at the conference including Dr. Natalia Cernichiaro, assistant professor of diagnostic medicine and pathobiology, who discussed the use of data to investigate outbreaks. Dr. Mike Sanderson, a professor in the same department, outlined the Secure Beef Supply program.
Dr. Mike Miesner, clinical associate professor and section head of Livestock Services discussed common diseases that can look like more serious trans-boundary diseases. Professor emeritus Dr. Jerome Nietfeld reviewed differential diagnoses of transboundary diseases, and Dr. Lina Mur, research assistant professor in infectious diseases epidemiology, gave an overview of the global movement of transboundary animal diseases.
Dr. Gregg Hanzlicek, assistant professor and director of Production Animal Field Investigations, spoke about disease trends as determined by diagnostic submissions to the Kansas State Veterinary Diagnostic Laboratory. Winding up the conference was Dr. Bob Larson, professor of production medicine, who covered clinical diagnostic interpretation.

Scientists Learn History of 1918 Spanish Flu at Ft. Riley
By Season Osterfeld | 1ST INF. DIV. POST
More than 25 scientists from around the globe visited Fort Riley May 10 to hear the history of the 1918 Spanish Flu outbreak at the installation and tour the museums.
The scientists were in Manhattan, Kansas, May 7 to 10 for the 8th International Conference on Emerging Zoonosis hosted by staff of Kansas State University. The conference is held every three years and consists of an interdisciplinary forum of physicians, veterinarians, epidemiologists, immunologists, virologists, microbiologists, public health experts and others. During the event, the transmission of infectious diseases from animals to humans and the economic impact of transboundary diseases were discussion topics.
With the assistance of retired Lt. Col. Arthur DeGroat, director of military affairs at Kansas State University, and Capt. Jamie Pecha, 1st Infantry Division preventive medicine officer, the international scientists received the history of the H1N1 Influenza, or Spanish Flu, that struck Fort Riley and spread across the world in 1918.
Fort Riley is believed to be the origin of the world-wide epidemic that killed millions, said Robert Smith, director of the museum division at Fort Riley.
“It was probably the greatest pandemic the world has ever seen,” he said. “They (researchers) think it killed between 2 and 4 percent of the world’s population. It was even greater than the bubonic plague back in the 14th century.”
Over lunch at Demon Dining Facility, Smith presented the history of the Spanish Flu at Fort Riley, as well as background on the installation and living conditions of Soldiers at that time. With a smirk, Smith told the scientists that patient zero was an Army cook named Albert Gitchell.
“They thought it mutated from pigs and then infected some Soldiers, some draftees, from Pascal County, Kansas, and they came here to train at Fort Riley and then the first recorded flu case here was a cook of all people,” he said.
Stephanie Hober, grant specialist, Kansas State University Center of Excellence for Emerging and Zoonotic Animal Diseases, said the tour and history were enjoyable and gave the group local background information on an epidemic several have studied.
“They’re getting to see the historical significance of Fort Riley in the outbreak of the Spanish Flu and the impact it had on the surrounding area here in the time it happened and the advances they’ve made since that time,” she said.
Understanding the history of the 1918 Spanish Flu and how it spread through a military installation, across the nation and internationally helps scientists develop a larger picture on how viruses and diseases transform into pandemics and on to epidemics, said conference co-host Dr. Jürgen Richt, from Kansas State University’s Center of Excellence for Emerging and Zoonotic Animal Diseases.
“It’s history and it’s very good that Fort Riley is a historic place and has a historian who is very able to describe well the history of how from Fort Riley these disease evolved and causes millions and millions of deaths,” Richt said. “It’s very important to have this historical perspective.”
Richt said the conference gets the scientists and experts communicating across disciplines when they normally would not. They can exchange information and work together to understand, treat and prevent diseases that travel between humans and animals.
“We have to bring these people together, they often don’t speak,” he said. “The medical doctors don’t speak with the veterinarians and vice versa and we can solve these problems so far. These zoonosis can become epidemics … We have to understand, not only from the human side, but also what’s going on in the animal reservoirs, and only then can we have a clear picture of what the risks are for these diseases to spread and come to our shores and what we need to stockpile now, like (Middle East Respiratory Syndrome) vaccines … These are the kinds of questions we have to address and that’s why we bring together epidemiologists, virologists, bacteriologists and so on.”

CEEZAD Executive Take Part in “Grands Témoins” Conference on Ebola in Zaire
The deputy director of the Center of Excellence for Emerging and Zoonotic Animal Diseases (CEEZAD) took part in an international conference on “Eco-health and disease emergence” held March 2-3 at the University of Kinshasha, in the Democratic Republic of Congo.
Dr. J.P. Gonzalez was one of several “grands témoins” (great witnesses) at the medical science conference, which attracted about 200 participants. The term ‘grands témoins’ refers to expert attendees chosen for the important role they play in the development of public health systems and processes in developing nations.
He was one of five scientists invited, and was chosen due to his expertise in the understanding of disease emergence, preparedness and control.
Dr. Gonzalez’ role involved giving presentations as well as mentoring sessions with students and post-doctoral attendees. He also presented sessions on publishing in scientific manuscripts and journals, and on granstsmanship.
He said he came away from the conference with a sense that progress was being made in broadening the understanding of the dangers posed by Ebola and other hemorrhagic or highly infectious viral diseases. “I had the opportunity to discuss and mentor master students and doctoral students and I was impressed by the quality of their work and projects, their engagement, their knowledge of field work,” he said. “Also I was able to identify health priorities – for example, zoonosis -- of interest for future research of interest for CEEZAD.”
Dr. Gonzalez said he and his fellow “grands témoins” sensed gains in how the young scientist attendees understand the methodology they develop, and also in how they will be able to use the most advanced technologies - when available - to produce knowledge in science. “Also we were impressed by their understanding of biotechnology, biostatistics and the use of spatial epidemiology – for example, geographical information systems,” he said.
According to the World Health Organization, the Ebola virus disease (EVD), formerly known as Ebola fever, is a severe, often fatal illness in humans. First reported in 1976 in central Africa (On the edge of the Ebola river, Democratic Republic of Congo), the virus is transmitted to people from wild animals and spreads in the human population through human-to-human transmission. The average EVD case fatality rate is above 50 percent. The most recent outbreak in West Africa has involved major urban as well as rural areas.
Throughout the two-day meeting, Dr. Gonzalez said the main messages were:
The essential nature of fieldwork as a pre-requisite to research.
The importance of exchanges, with the population at risks, through community counseling and community participation. The necessity for always questioning previous findings.
The immense progress of knowledge made possible by trans-disciplinary research projects.
Gonzalez said that in order to understand why infectious diseases emerge, it is important to focus research on that question during the period when there is no epidemic activity. This enables scientists to see which variables are critical to sparking an outbreak. “When an outbreak/epidemic is going on, it is too late for research and quite impossible to understand the fundamentals of emergence,” he said. “Focusing and favoring research during the inter-epidemic period encourages the reaching of a consensus among all participants.”
He emphasized that some findings would be valuable to non-scientists as well as to scientists. Among those was the need for an increased understanding that everything - at least in terms of health - is interconnected. “That means any action on one of the actors of the health system – of natural and/or anthropic origin -- can be beneficial or disastrous for the pathogen dynamic , whether in the form of a disease, outbreak or pandemic,” he said.
With specific reference to Ebola fever, Dr. Gonzalez noted that people in central Africa, where it is prevalent, have a great knowledge of its intrinsic risk, having witnessed sporadic cases and outbreaks for decades. “But they are lacking knowledge to control and respond properly and efficiently,” he said, adding, “this what we are doing actively now in central and west Africa: Community counseling, and community participation.”
With respect to both Ebola fever and other highly infectious diseases, Americans – both civilian and non-civilian – need to understand the importance of not putting themselves at risk.
