Deer can be infected with SARS-Co-V-2 virus

The director of the Center of Excellence for Emerging and Zoonotic Animal Diseases (www.ceezad.org) is quoted in a recently published article in the Topeka Capital Journal on the presence of SARS-CoV-2 infections in wild white-tailed deer.

Dr. Juergen A. Richt said that while researchers have established that white-tailed deer can become infected with and spread the SARS-Co-V-2 virus, the meat taken from such deer should be safe to eat as long as it is properly handled, cleaned and cooked.

Deer season opened for some groups in early September and continues through January. Specific dates hinge on shooting classes and weapons.

CEEZAD Director quoted in National Geographic Report on SARS-CoV-2 infections in white-tailed deer

The Director of the Center of Excellence For Emerging and Zoonotic Animal Diseases (www.ceezad.org) is among experts quoted in a recently published article in National Geographic on the presence of SARS-CoV-2 in white-tailed deer.

Dr. Juergen Richt, Regents Distinguished Professor at Kansas State University and CEEZAD director, commented on the significance of a recent finding of the virus’s presence in white-tailed deer found in four states: Michigan, Illinois, Pennsylvania and New York.

The article, written by Dana Fine Maron, was published Aug. 2 and can be read at Wild U.S. deer found with coronavirus antibodies (nationalgeographic.com)

Dr. Richt was asked to comment on the risk of White-tailed deer spreading SARS CoV-2. He expressed concern that the presence of the virus in  wild animals may constitute what is known as a “secondary virus reservoir” – that is, a place where it can hide, spread and develop largely free from the kinds of restraints normally imposed on it by public health officials.

Dr. Richt said that if the virus is circulating in animal species, it could continue to evolve, perhaps in ways that could make it more severe or more transmissible. That could undermine efforts to slow the pandemic.

CEEZAD researchers have conducted numerous studies since the emergence of SARS-CoV-2  that have been designed to ascertain its ability to infect various species of animals, and to explore the question of whether the virus can be transmitted from susceptible animals to other animals including humans.

ASF identified in the Dominican Republic

The U.S. Department of Agriculture’s (USDA) Foreign Animal Disease Diagnostic Laboratory has confirmed that African Swine Fever virus is present in the Dominican Republic.

This marks the first time in decades that ASF has been found in the Americas.

AFS is a highly contagious and fatal disease of both wild and domestic swine that causes high mortality and substantial economic damage in places where it is found. The disease is widespread in Africa, parts of Europe and Asia. It has never been found in the United States.

USDA officials said the department’s Animal and Plant Health Inspection Service (APHIS) has numerous interlocking safeguards in place to prevent ASF from entering the United States.  Pork and pork products from the Dominican Republic are currently prohibited entry as a result of already existing classical swine fever restrictions.  Additionally, the Department of Homeland Security’s Customs and Border Protection (CBP) is increasing inspections of flights from the Dominican Republic to ensure that travelers do not bring prohibited pork products to the United States.  CBP will also be ensuring that garbage/swill from these airplanes are properly inactivated and disposed of to prevent the transmission of ASF.  

In China alone, the ASF outbreak is estimated to have killed more than one-third of the nation’s pig population, the world’s largest, with losses in the millions of pigs and billions of dollars..

SARS-CoV-2 antibodies found in white-tailed deer in the U.S.

Tests completed recently by the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) have determined that deer populations in at least four states have been exposed to the SARS-CoV-2 virus.

SARS-CoV-2-specific antibodies were detected in 33 percent of deer samples collected in Illinois, New York, Michigan, and Pennsylvania. The presence of antibodies is an indication that the animals have been exposed to the SARS-CoV-2 virus.

Researchers said they did not know whether the deer were exposed through people, the environment, other deer, or another animal species. The USDA scientists said that based on the evidence they have to date, they believe the risk of animals spreading SARS-CoV-2 to people is low.

These findings are in line with testing conducted by researchers at the Center of Excellence for Emerging and Zoonotic Animal Diseases (www.CEEZAD.org) that showed white-tailed deer are highly susceptible to SARS-CoV-2 infection and are very efficient in transmitting the virus to other deer.

Work of pioneering veterinarian a source of inspiration to CEEZAD’s/CEZID’s director

Some of the roots of the drive to learn that motivates one researcher at the Center of Excellence For Emerging and Zoonotic Animal Diseases (CEEZAD; www.ceezad.org) and Center on Emerging and Zoonotic Infectious disease (CEZID; www.ksu.edu/cezid.org) may be traced back to a pioneer in the field of veterinary medicine.

Dr. Helen S. Richt Irwin, a long-time veterinarian and the first female graduate of Kansas State University’s College of Veterinary Medicine, was the great aunt of Dr. Juergen A. Richt, Regents and University Distinguished Professor at K-State and CEEZAD’s and CEZID’s director.

Dr. Helen Richt, who received her veterinary degree from K-State in 1932, came to the veterinary program from her home near Omaha, where she had been born in 1910. Her father ran a farm and co-operated a feedlot there.

Surrounded by animals, the young girl grew up with a love of them, especially dogs and cats. The fourth of 11 children, family members characterized her as her father’s ‘shadow’ on the farm.

In a 2005 book about female veterinary medicine graduates at K-State, Dr. Helen Richt’s sister, Edith, told author Lesley Gentry that Helen was “out-doorsy, but not a tomboy.”

That plus a family connection with Dr. Donald Munn Walker, a local veterinarian who partnered with her father in an Ag-related business, motivated the future Dr. Helen Richt to aspire to join the veterinary field. Following her graduation from high school in Omaha in 1928, she applied for admission to the K-State veterinary college.

To that point, no woman had ever been admitted to the college, but Helen broke the precedent, entering the college in the fall of 1928. At K-State, she pursued her veterinary studies, applying such spare time as she had to activities of the Women’s Athletic Association. She enjoyed baseball, volleyball and hockey.

As a sophomore she became the first woman member of the Kansas State student chapter of the American Veterinary Medicine Association. She completed the 164-credit hour program and graduated as a DVM on June 2, 1932, in a class of 19, winning the Franklin Prize in Pathology. By then she had already passed her board exams.

Even as a student, Helen’s desire to join the veterinary profession received attention. In 1932 various newspaper articles followed her progress: her appearance before the state’s veterinary board, her receipt of a veterinary license, and her decision to launch a pet hospital.

Shortly after receiving her license, she briefly returned home to Omaha where her veterinary skills turned out to be needed. A family pet, a dog, injured a leg in a fence, necessitating amputation surgery.  Dr. Helen Richt performed the surgery at home while family members watched. The dog recovered.

In 1933 as a grad technician, she worked at K-State alongside Dean Ralph Dykstra.

In December of 1934, she married Dr. William F. Irvin, also a KSU veterinary medicine graduate. They jointly purchased the City Veterinary Hospital, in Tulsa in 1935. Helen specialized in tonsillectomies and cesareans. She was described as good at calming stressed animals, and capable of handling the largest dogs.

The family’s first child was born in 1937. That same year she was appointed secretary of the AVMA section on small animals. She thus became the first woman to hold an AVMA office.

The couple built a new hospital structure in 1942. By then a second son had been born; a third followed in 1945, after which Dr. Helen Richt retired from active practice to care for the couple’s family. But she maintained involvement in AVMA, serving as secretary to the Oklahoma Vet Med Association auxiliary in 1955.

Following her husband’s death in 1959 airplane accident, Dr. Helen Richt sold the Tulsa practice. Still she remained active in AVMA activities, being elected treasurer of the Oklahoma Veterinary Medicine Association in 1960.

When her health began to deteriorate, she moved back to Omaha, where she died following a prolonged battle with cancer in 1990.

Dr. Helen Richt’s career became a model for aspiring veterinarians. She once told a reporter, “it is hard work, but there is a lot of satisfaction in helping some poor dog or cat. It’s a matter of loving animals.

“I’ve always been interested in taking care of unfortunate creatures,” she added.

In her book, Gentry described Dr. Helen Richt as “a woman with great determination who was not afraid to challenge new ground…a wonderful person who has left an indelible mark on the face of women in veterinary medicine.”

In her honor, the Helen Richt Scholarship in veterinary medicine was created at K-State.

Dr. Juergen Richt, who has been at KSU since 2008, is following in his great-aunt’s footsteps by continuing to advance veterinary research with a focus on emerging and zoonotic diseases.

“Although I did not know Dr. Helen Richt personally, her story, her commitment to the veterinary profession and her dedication to the advancement of veterinary science provide a great source of inspiration to me to improve the veterinary knowledge base today,” Dr. Juergen Richt said.

CEEZAD team’s work on SARS-CoV-2 stability highlighted in KSU press release

Research by a team from the DHS Center of Excellence for Emerging and Zoonotic Animal Diseases (CEEZAD; www.ceezad.org) is being featured in a Kansas State University news release.

The research, led by Dr. Juergen A. Richt, Regents and Kansas State University Distinguished Professor and director of CEEZAD and the NIH Center on Emerging and Zoonotic Infectious Diseases (CEZID; www.ksu.cezid.org), focused on the issue of the environmental stability of the SARS-CoV-2 virus on various common surfaces.

It was included in an article published by KSU’s Division of Communications and Marketing highlighting various university-wide efforts to research and combat the SARS-CoV-2 virus.

The study resulted in several important insights into SARS-CoV-2 survival on various surfaces such as concrete, polypropylene, stainless steel and galvanized steel, nitrile gloves, Tyvek, N95 masks, Styrofoam, cardboard, rubber and glass.

It also found:

  • The virus survived the longest — 21 days after contamination — on surfaces under winter conditions.
  • In spring and fall conditions, the virus survived up to seven days.
  • No infectious virus was found three days after contamination under summer conditions.
  • Under indoor conditions, the virus survived up to 4 days.

CEEZAD director’s research into SARS-CoV-2 and houseflies detailed in verywellhealth article

Research conducted by a team of scientists from KSU and USDA including the director of the DHS Center of Excellence for Emerging and Zoonotic Animal Diseases (CEEZAD; (CEEZAD; www.ceezad.org) and the NIH Center on Emerging and Zoonotic Infectious Diseases (CEZID; www.ksu.edu/cezid) has found that common houseflies can carry infectious SARS-CoV-2 but are not a likely source for the spread of the SARS-CoV-2 virus.

The research findings were reported in the April 20 edition of the journal Parasites and Vectors (Balaraman et al., 2021. Mechanical transmission of SARS-CoV-2 by house flies. Parasit. Vectors. 14:214), and detailed in an article published in the April 27 edition of verywellhealth. https://www.verywellhealth.com/house-flies-covid-19-carriers-5180607

Study co-author Dr. Juergen A. Richt, Regents and University Distinguished Professor at Kansas State University and Director of CEEZAD and CEZID, said the study was undertaken because “there are many cases of COVID-19 where we don’t know how someone contracted the virus.”

Richt said the study focused on houseflies because they are “known to be attracted to biological fluids that can be contaminated with the virus” and are also known to transmit bacterial, parasitic, and viral diseases to humans and animals. The authors concluded that the chances of contracting the SARS-CoV-2 virus from a fly are slim.

Even so, they did find a need for additional studies to determine whether housefly transmission occurs naturally, and the potential public health implications of any such natural transmission.

CEEZAD article on a theory for SARS-CoV-2 published by leading biology journal

An important study conducted by researchers at the Center of Excellence for Emerging and Zoonotic Animal Diseases (CEEZAD) has been published by Cell, one of the world’s leading journals on biology with a ranking of #1 out of 298 journals on biochemistry and molecular biology.

The study looks at the possible use of a topoisomerase 1 inhibitor to suppress inflammation induced by SARS-CoV-2 in the respiratory tract.

In the Cell article, CEEZAD researchers report on research demonstrating that topoisomerase 1 (TOP1) inhibition does down-regulate inflammation induced by SARS-CoV-2 and improves the clinical signs associated with SARS-CoV-2.

The study’s co-authors include Dr. Juergen A. Richt, the Regents and University Distinguished Professor at Kansas State University and director of two national Centers of Excellence, CEEZAD (www.ceezad.org) and CEZID (www.ksu.edu/cezid). Other co-authors include Natasha Gaudreault, David Meekins, Sabarish Indran, Igor Morozov and Jessie Trujillo, all of KSU.

The ongoing pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is currently affecting millions of lives worldwide. Large retrospective studies indicate that an elevated level of inflammatory cytokines and pro-inflammatory factors are associated with both increased disease severity and mortality. Using multidimensional epigenetic, transcriptional, in vitro, and in vivo analyses, the researchers found that therapeutic treatment with two doses of topotecan (TPT), an FDA-approved TOP1 inhibitor, down-regulates infection-induced inflammation in hamsters. TPT treatment as late as 4 days post-infection reduces morbidity and rescues mortality in a transgenic mouse model.

These results support the potential of TOP1 inhibition as an effective host-directed therapy against severe SARS-CoV-2 infection.

TPT and its derivatives are inexpensive clinical-grade inhibitors available in most countries. Clinical trials are needed to evaluate the efficacy of repurposing TOP1 inhibitors for severe coronavirus disease 2019 (COVID-19) in humans.

CEEZAD/CEZID Director quoted in an article on the emergence 

of a new strain of avian influenza

The Director of the Center of Excellence For Emerging and Zoonotic Animal Diseases (CEEZAD; http://www.ceezad.org) and the Center on Emerging and Zoonotic Infectious Diseases (CEZID; (www.ksu.edu/cezid)) is one of several experts on zoonotic diseases quoted in a recent article on the emergence of a variation of avian influenza that has spread to humans.

Dr. Juergen A. Richt, Regents Distinguished Professor at Kansas State University and Director of CEEZAD and CEZID, is among experts cited in an article published by Verywellhealth. The article, which can be read by following the link below, discusses concerns over the emergence of the H5N8 variant of avian influenza in Russia. The article was written by Korin Miller.

The H5N8 influenza strain emerged in a group of workers who were exposed to infected bird flocks. The workers did not develop influenza-like symptoms and there was no evidence that they passed the virus on to other people. While outbreaks of the H5N8 strain have been detected in various countries in the past few months, this is the first time the H5N8 strain was transmitted from infected birds to humans. In the article, Dr. Richt notes that it is not yet clear the extent to which the new strain poses a serious threat to humans. At a minimum, however, it appears to be “rather concerning” to poultry due to its potential lethality.

CEEZAD research into reinfection of cats with SARS CoV-2 is published

Research by scientists from the Center of Excellence for Emerging and Zoonotic Animal Diseases (CEEZAD) into the protection of previously exposed cats from re-infection by the SARS CoV-2 virus has recently been published.

The article is titled “Experimental re-infected cats do no transmit SARS CoV-2.” It was published in the Journal “Emerging Microbes and Infections” this month.

Co-authors include Dr. Juergen A. Richt, Dr. Igor Morozov, Natasha Gaudreault, David Meekins, Jessie Trujillo, Daniel W. Madden, Konner Cool, Bianca Libanori Artiaga, Chester McDowell, Dashzeveg Bold, Velmurugan Balaraman, Taeyong Kwon, Jamie Henningson, and Wenjun Ma, all affiliated with KSU and CEEZAD.

In the article, the authors note they and others have previously demonstrated that cats are susceptible to SARS-CoV-2 infection and can efficiently transmit the virus to naïve cats. 

In this study, the CEEZAD scientists address whether cats previously exposed to SARS-CoV-2 can be re-infected with SARS-CoV-2. In two independent studies, SARS-CoV-2-infected cats were re-challenged with SARS-CoV-2 at 21 days post-primary challenge (DPC) and necropsies performed at 4, 7, and 14 days post-secondary challenge (DP2C). 

Sentinels were comingled with the re-challenged cats at 1 DP2C. Clinical signs were recorded, and nasal, oropharyngeal, and rectal swabs, blood, and serum were collected and tissues examined for histologic lesions. Viral RNA was transiently shed via the nasal, oropharyngeal, and rectal cavities of the re-challenged cats. Viral RNA was detected in various tissues of re-challenged cats mainly in the upper respiratory tract and lymphoid tissues, but less frequently and at lower levels in the lower respiratory tract when compared to primary SARS-CoV-2 challenged cats. Histologic lesions that characterized primary SARS-CoV-2 infected cats at 4 DPC were absent in the rechallenged cats. 

The results showed that naïve sentinels co-housed with the re-challenged cats did not shed virus or seroconvert. Together, the results indicate that cats previously infected with SARS-CoV-2 can be experimentally re-infected with SARS-CoV-2; however, the levels of virus shed were insufficient for transmission to co-housed naïve sentinels. 

The researchers concluded that SARS-CoV-2 infection in cats induces immune responses that provide partial, non-sterilizing immune protection against re-infection.

John Deere article features CEEZAD Director’s work

The Director of the Center of Excellence for Emerging and Zoonotic Animal Diseases is featured in an article contained in the most recent edition of “The Furrow,” the monthly magazine of John Deere Inc.

The article, titled “Pandemic Fighters,” discusses efforts by prominent agricultural scientists to combat a variety of diseases that threaten the nation’s food supply. The work of Dr. Juergen A. Richt, CEEZAD Director and Regents and University Distinguished Professor at Kansas State University, is extensively discussed.

Written by Steve Werblow, the article focuses on Dr. Richt’s work combatting Rift Valley Fever. Prevalent in parts of Africa and the Arabian Peninsula, Rift Valley Fever is a mosquito-transmitted disease that affects sheep, cattle, goats, and camels, and also is transmissible to humans.

The human case fatality rate is about 10 percent. “If Rift Valley Fever virus somehow comes onto our shores, it will find very fertile ground to establish itself,” he is quoted in the article as saying.

CEEZAD research into Ebola virus vaccine is published

Research by scientists from the Center of Excellence for Emerging and Zoonotic Animal Diseases (CEEZAD) into the safety of a human vaccine for use in combatting the Ebola virus has recently been published.

The research did not involve work with the Ebola virus.

The article is titled “High dose of vesicular stomatitis virus-vectored Ebola virus vaccine causes vesicular disease in swine without horizontal transmission.” It was published in the Journal “Emerging Microbes and Infections” this month.

Co-authors include Dr. Juergen A. Richt, Dr. Igor Morozov, David Meekins, Jessie Trujillo, Sun-Young Sunwoo, Kinga Urbaniak, In Joong Kim, Sanjeev Narayanan, Sabarish Indran, and Wenjun Ma, all affiliated with KSU and CEEZAD.

In the article, the authors note that the recent impact of Ebola virus disease (EVD) on public health in Africa demonstrates the need for a safe and efficacious vaccine to control outbreaks and mitigate its threat to global health. The research focuses on the potential of a vaccine called ERVEBO®, which is an effective recombinant Vesicular Stomatitis Virus (VSV)-vectored Ebola virus vaccine (VSV-EBOV) that was approved by the FDA and EMA in late 2019 for use in the prevention of EVD. 

Since the parental virus VSV, which was used to construct ERVEBO®/VSV-EBOV, is pathogenic for livestock and the virus may be shed at low levels by vaccinated humans, widespread deployment of the vaccine required investigation into its infectivity and transmissibility in VSV-susceptible livestock species. 

The researchers performed a comprehensive clinical analysis of the ERVEBO®/VSV-EBOV vaccine virus in swine to determine its infectivity and potential for transmission. A high dose of ERVEBO®/VSV-EBOV resulted in VSV-like clinical signs in swine, with a proportion of pigs developing ulcerative vesicular lesions at the nasal injection site and a distant site, the feet.

Uninoculated contact control pigs co-mingled with ERVEBO®/VSV-EBOV -inoculated pigs did not become infected or display any clinical signs of disease, indicating the vaccine is not readily transmissible to naïve pigs during prolonged close contact. In contrast, virulent wild-type VSV had a shorter incubation period and was transmitted to contact control pigs. 

These results indicate that the ERVEBO®/VSV-EBOV vaccine causes vesicular illness in swine when administered at a high dose. Moreover, the study demonstrates the ERVEBO®/VSV-EBOV vaccine is not readily transmitted to uninfected pigs, encouraging its safe use as an effective human vaccine.

CEEZAD Director’s research featured in MIT article

Research by the Director of the Center of Excellence for Emerging and Zoonotic Animal Diseases is featured in a recently published article in the MIT Technology Review.

The research, by CEEZAD Director Dr. Juergen A. Richt, focuses on methods of improving the resistance of pigs to influenza. The article, titled “Lessons From the Pig Epidemic,” was written by Antonio Regalado, and published on Dec. 12.

In the article, Regalado reports on Dr. Richt’s work in collaboration with Genus, a British company specializing in animal genetics. The focus of the research is an effort to make pigs more resistant to swine flu by modifying the pigs’ genetic makeup.

Specifically, he is testing the feasibility of removing various genes, called proteases, which the flu and other pathogens require in order to enter cells. If these key proteases can be removed, then it may improve pigs’ resistance to the flu.

“What we want is to make (pigs) resistant to all influenzas, from all walks of life,” Richt said.

The work is challenging because proteases are necessary to life. The challenge lies in finding the extent to which they can be removed or modified without harming the pig. But Richt noted that finding the right combination can lead to “less virus replication, les virus re-assortment,” and eventually to a reduced evolution of the virus.

Dr. Richt to discuss Covid-19 research in January 27 lecture at the Mossberg Honors Symposium

The Director of the Center of Excellence for Emerging and Zoonotic Animal Diseases (CEEZAD) and the Center on Emerging and Zoonotic Infectious Diseases (CEZID) at Kansas State University will lecture at the University of Kansas in January on recently conducted research.

Dr. Juergen A. Richt, Regents and University Distinguished Professor at Kansas State University, will deliver the keynote address at KU’s Mossberg Honors Symposium Jan. 27. His address, titled, “Ventures into Covid-19 Research: About Pigs, Cats and Hamsters,” will take place at 9 a.m.

The symposium is presented by the School of Pharmacy at KU. It will be conducted via Zoom.

The unprecedented current pandemic caused by SARS CoV-2 has accelerated research on the epidemiology and pathogenesis of the virus. Since humans do not have pre-existing immunity to SARS-CoV-2, there has been an urgent need to develop and test therapeutic agents and vaccines. Both the U.S. and the World Health Organization have launched campaigns to develop and test therapeutic agents and vaccines. That testing has necessarily involved animal models that provide measurable readouts for potential countermeasures.

In his lecture, Dr. Richt will discuss some of the Covid-19-related research conducted in his laboratory at KSU. The focus will be on describing preclinical animal models for Covid-19 and their use to inform public and animal heath as well as determining the efficacy of therapeutic agents.
