NIFA research awards total more than $1.7 million

Faculty quintet acquires impressive set of grants through Agriculture and Food Research Initiative

Dr. Hans Coetzee works with cattleThe USDA’s National Institute of Food and Agriculture (NIFA) recently announced 39 new research awards totaling $14.3 million to help maintain healthy agricultural animals.

Five awards worth more than $1.7 million in total have been designated to CVM researchers. Funding is provided through NIFA’s Agriculture and Food Research Initiative (AFRI) program, authorized by the 2014 Farm Bill.

The awards are:

Dr. Hans Coetzee seeks to take the pain out of cattle procedure

 

Dr. Hans Coetzee works with cattle

 

Dr. Hans Coetzee takes notes while performing research on pain relief in cattle.

A calf’s ear may be the best location for delivering a new vaccine with a dual purpose: relieving pain while also preventing unwanted pregnancies in cattle.

This approach was deemed sound enough to merit a $500,000 grant from the USDA’s National Institute of Food and Agriculture (NIFA) for Dr. Hans Coetzee, head of anatomy and physiology in the College of Veterinary Medicine at Kansas State University and his collaborator, Dr. Doug Jones, a professor at Iowa State University.

Dr. Coetzee’s career has long focused on finding ways to relieve pain in cattle, which has already resulted in national and international recognition earlier this year. In July, he was presented with the 2017 Animal Welfare award by the American Veterinary Medical Association. In August, he was invited South Korea where he was presented with the CEVA Global Animal Welfare Award by the World Veterinary Association.

In October, NIFA announced a list of 39 projects nationwide to receive funding through its Agriculture and Food Research Initiative program. The College of Veterinary Medicine was selected to receive more than $1.7 million in funding, including Dr. Coetzee’s project, “Optimizing an Immunocastration Vaccine Ear Implant to Prevent Pain Associated with Bovine Castration.”

“Our project will specifically work to optimize a long-lasting vaccine implanted under the skin of the ear to direct the calf's immune response to disrupt the development of the male reproductive organs,” Dr. Coetzee said. “Knowledge gained from this proposal will address current animal welfare concerns and will have an immediate and significant impact on the sustainability of U.S. beef production systems.”

Dr. Coetzee explained how physical castration of male calves destined for beef production has been one of the most common livestock management practices performed in the United States, amounting to about 10 million procedures per year. Benefits include a reduction in unwanted pregnancies, improved meat quality and fewer injuries in confinement operations.

“Pain experienced during physical castration is a significant animal welfare concern,” Dr. Coetzee said. “It is therefore critical for livestock producers to develop practical and cost-effective strategies to reduce the negative impact of surgical castration on beef cattle welfare and production. The long-term goal of our research group is to improve animal welfare through the development of practical strategies to alleviate pain associated with castration.”

In collaboration with researchers affiliated with the Nanovaccine Institute at Iowa State University, Dr. Coetzee’s research group has already developed a prototype of an implant that reduces testicular development in calves, but wants to determine the impact of age on the ability of the vaccine implant to produce effective immunocastration in calves throughout the production cycle.

“Our hypothesis is that the implant will be effective regardless whether it is administered to newborn calves, weaned calves or yearling calves,” Dr. Coetzee said. “We believe this research will deliver a technology that can eliminate pain associated with castration in cattle regardless of when the immunocastration implant is administered during the production cycle.”

This research will be supported by the Agriculture and Food Research Initiative Competitive Grant No. 2017-67015-27124 from the USDA National Institute of Food and Agriculture.

Dr. Waithaka Mwangi works to develop upgradeable cattle vaccine

 

Dr. Waithaka Mwangi

 

Dr. Waithaka Mwangi talks about some of his research involving cattle antibodies.

Like a cell phone user might download the latest updates for an app, Dr. Waithaka Mwangi sees a possibility that cattle vaccines can be updated to protect against the most recent strains of disease-causing viruses.

Dr. Mwangi's theory received a favorable review from the USDA's National Institute of Food and Agriculture (NIFA), resulting in a $495,000 grant for the associate professor in the College of Veterinary Medicine. In October, NIFA announced a list of 39 projects nationwide to receive funding through its Agriculture and Food Research Initiative program. The College of Veterinary Medicine was selected to receive more than $1.7 million in funding awards, including Dr. Mwangi's project, "Improved Vaccine Platforms for Safe and Effective Control of Bovine Viral Diarrhea Virus (BVDV)."

"We are addressing a critical need for improved broadly protective BVDV vaccines that are free of negative effects and are affordable," Dr. Mwangi said. "The expected outcome will thereby increase productivity and profitability of U.S. cattle industry. Just as importantly, the technology will allow rapid vaccine upgrade to incorporate protective components from new BVDV strains that will emerge in future."

According to USDA statistics and others, the cattle industry accounts for roughly 40 percent of the total market value of U.S. agriculture. Because infections with BVDV represent a major economic loss, BVDV is categorized as a "High Priority Disease" of economic importance to U.S. animal agriculture, which Dr. Mwangi said creates a need for developing better vaccines.

"We have developed a new vaccine formulation that consists of several protective components from different BVDV strains," Dr. Mwangi elaborated. "These components were selected using the latest scientific approaches that utilized cumulative knowledge generated so far from BVDV vaccine development studies."

Dr. Mwangi's lab will test whether immunization of cattle with this new vaccine will confer protection against a majority of BVDV strains present in America.

"We expect that this new vaccine will be safe, affordable and capable of inducing protection against multiple BVDV strains," Dr. Mwangi said. "These expected outcomes will reduce losses caused by BVDV and thereby contribute to an increase in the efficiency of beef and dairy animal production systems."

This research will be supported by the Agriculture and Food Research Initiative Competitive Grant No. 2017-67015-26802 from the USDA National Institute of Food and Agriculture.

Dr. Weiping Zhang tests broad approach for vaccine development against post-weaning diarrhea in pigs

 

Dr. Weiping Zhang and his lab

 

Dr. Weiping Zhang (center) likes to take a team approach with members of his lab. From left: Carolina Garcia, grad student; Jiachen Huan, grad student; Dr. Zhang; Dr. Qiangde Duan, postdoc; and Ti Lu, grad student.

Can one size fit all? That’s the challenge being addressed by Dr. Weiping Zhang, professor of microbiology in the College of Veterinary Medicine at Kansas State University.

A new grant from the USDA’s National Institute of Food and Agriculture (NIFA) for $460,000 will enable Dr. Zhang to apply this approach as a cost-effective and efficient solution for controlling post-weaning diarrhea (PWD) in swine.

“Vaccination is probably the most practical and effective method to control diseases for swine producers, but no effective PWD vaccines have been developed due to technical challenges at inducing broad immunity against the different strains of diarrhea caused by enterotoxigenic E. coli (ETEC),” Dr. Zhang explained. “We propose to innovatively produce multiepitope fusion antigen (MEFA) and a live vaccine inducing broadly protective local mucosal immunity, and then, unambiguously assess efficacy of this vaccine in piglet challenge studies. With strongly supportive data from preliminary studies, in conjugation with years of combined experience of two investigators in ETEC research and vaccine development, we believe our proposed research will be completed.”

Dr. Zhang added that an effective PWD vaccine would save hundreds of millions of dollars each year for US swine producers, while also reducing antibiotic use. Innovation applied in this study could potentially be applied toward vaccine development against other diseases.

In 2016, Dr. Zhang was awarded a $2.1 million National Institutes of Health R01 grant for early vaccine research. The NIH has awarded two additional grants to Dr. Zhang in the last four years to develop vaccines against E. coli diarrhea.

“Diarrhea continues to be a leading cause of death in children under five years of age, and enterotoxigenic E. coli (ETEC) is the most common bacterial cause of children's diarrhea,” Dr. Zhang said. “Currently, there are no available vaccines against ETEC-associated diarrhea. Whole-cell vaccine candidates have been under development, but require further improvements because they provide inadequate protection and produce unwanted adverse effects.”

“Effective vaccines for ETEC have proved to be very challenging,” said Dr. Frank Blecha, associate dean for research in the veterinary college. “Dr. Zhang’s vaccine development strategy for ETEC using multiepitope fusion antigens holds great promise for a vaccine that will limit diarrheal deaths in animals, and it may also have relevance to human health too.”

This research will be supported by the Agriculture and Food Research Initiative Competitive Grant No. 2017-67015-26632 from the USDA National Institute of Food and Agriculture.

Cats a Step Closer to FIP treatment

A clinical trial yields promising applications of antiviral compound

Peanut the cat

The numbers are looking good for treating a disease in cats that -- up to now -- has been 100 percent fatal. A field trial is having encouraging results from a treatment involving an antiviral compound developed at Kansas State University and Wichita State University.

Drs. Yunjeong Kim and KC Chang, virologists in the College of Veterinary Medicine, and Dr. William Groutas, a medicinal chemist at Wichita State University, have been collaborating since 2010 on the development of antiviral drugs for important human and animal viruses.

Peanut the cat

 

Peanut, a cat that had wet FIP. He is now in remission for 1 year.

 

Flora the cat

 

Flora, a cat that had wet FIP, is now in remission for 1.5 years.

“Over the course of the last several years, we have generated antiviral compounds that potently inhibit the virus responsible for feline infectious peritonitis (FIP),” Dr. Kim said. “This finding led to a collaboration with Dr. Niels C. Pedersen at the University of California, Davis, for testing one of the compounds in a clinical trial with cats with naturally-occurring FIP for the last three years.”

FIP is a leading cause of death in kittens and young cats and is most common in indoor, multicat environments such as shelters and catteries. The researchers have just published findings in the Journal of Feline Medicine and Surgery: “Efficacy of a 3C-like protease inhibitor in treating various forms of acquired feline infectious peritonitis,” which is a follow-up publication of  http://journals.plos.org/plospathogens/article?id=10.1371/journal.ppat.1005531, published in PLOS Pathogens in 2016.

“The field trial of GC376 was the first antiviral treatment for naturally occurring FIP, and it was designed to address several questions,” Dr. Kim explained. “One of the questions was to find out whether antiviral treatment holds promise in FIP treatment.”

Dr. Kim said the study looked at patients with different forms of FIP: wet form, dry form and dry-to-wet form.

“They were at different stages with various clinical signs and were recruited into the trial,” Dr. Kim said. “A total of 20 cats received antiviral treatment and seven of those cats are currently in long-term remission. This trial gave us valuable information regarding which patient groups seem to have a better prognosis for a long-term remission. Typically, acute wet FIP progresses rapidly and kittens are usually euthanized within weeks of diagnosis. But six out of eight kittens with wet FIP that were admitted into the trial are currently in remission with the longest remission time at one and a half years.”

Other cats in the trial that were chronically ill also quickly improved on antiviral treatment and had varying duration of clinical remission before many them succumb to neurological disease later.

“This virus infects a cell type that can make its way to the CNS and it seems that this can occur fairly early in many, but not all, cats, although clinical signs may appear later” Dr. Kim mentioned. “This tells us that the key to long-term remission would be to start antiviral treatment before viruses have a chance to enter the CNS or establish chronic lesions that are hard to eliminate. Although kittens treated early seem to have a better chance for a cure, most of the affected cats are expected to benefit from antiviral treatment by improved quality of life, regardless of FIP forms.”

Dr. Kim emphasized how this was a small study consisting of various patient groups, and said a larger trial focusing on each patient group would be needed to confirm the findings.

“From this trial we learned the answer to the important question: antiviral treatment would be an essential component of effective FIP treatment and early diagnosis/treatment is the key to treatment success.” Dr. Kim said.

 

Dr. Susan Moore revises rabies immunology module for World Health Organization 

China DVM agreement signing ceremony

The World Health Organization (WHO) has just published a revised version of its module on rabies immunization, thanks to the work of Dr. Susan Moore, director of the Rabies Laboratory at Kansas State University, and Dr. Deborah Briggs, adjunct professor in the College of Veterinary Medicine and former executive director and current board member of the Global Alliance for Rabies Control (GARC).

China DVM agreement signing ceremony

The Immunological Basis for Immunization Series: Module 17: Rabies” is part of a series modules, on general immunology devoted to one of the vaccines recommended for the “Expanded Programme on Immunization,” i.e. vaccines against diphtheria, measles, pertussis, polio, tetanus, tuberculosis and yellow fever. Dr. Moore and Dr. Briggs served as the sole editorial team for this publication.

“The updated rabies immunology module was needed to compliment the anticipated update to WHO’s recommendations for pre- and post-exposure prophylaxis,” Dr. Moore explained. “These changes are due to recent findings on shortened vaccine regimens and intradermal administration; and will greatly benefit rabies prevention and control efforts in developing countries where the burden of human rabies deaths primarily occurs.”

Since the module series was started by WHO in 1993, it has been updated and extended to include other vaccines of international importance. The main purpose of the modules is to provide national immunization managers and vaccination professionals with an overview of the scientific basis of vaccination against a range of important infectious diseases. The modules also serve as a record of the immunological basis for the WHO recommendations on vaccine use, published in the WHO vaccine position papers.

In addition to serving as director of the Rabies Laboratory, Dr. Moore is a clinical assistant professor in the diagnostic medicine/pathobiology department in the College of Veterinary Medicine. The Rabies Laboratory is a part of the Kansas State Veterinary Diagnostic Laboratory.

ICCM research drives wheat straw forward as ethanol fuel source

Dr. Zhenzhen Shi and Dr. Majid Jaberi-DourakiWheat grown from the heartland may soon fill gas tanks.Thanks to an international and interdisciplinary collaboration, faculty at Kansas State University's Institute of Computational and Comparative Medicine and bioenergy researchers at Yangzhou University in China have marked a significant milestone for the production of ethanol fuel from wheat.

Their study, "Predictive temperature modeling and experimental investigation of ultrasonic vibration-assisted pelleting of wheat straw," was recently published in Applied Energy, which is considered the top-tier journal in the field of energy (ranked first out of 58 journals on energy).

Read more ...

Dr. Zhenzhen Shi and Dr. Majid Jaberi-Douraki
Drs. Zhenzhen Shi, left, and Majid Jaberi-Douraki, both with Kansas State University's Institute of Computational and Comparative Medicine, collaborated with researchers at a Chinese university on a project that could aid ethanol fuel production from wheat.

"To the best of our knowledge, previous studies haven't systematically investigated the underlying mechanisms for continuous temperature rise during pellet production, which hinder effective production of biomass pellets and directly reduce the final ethanol production," said Dr. Makod Jaberi-Douraki, an assistant professor of mathematics. "In this case, risk factors resulting in a significant temperature rise need to be identified for improving the pellet production and energy outputs."

Dr. Zhenzhen Shi, a post-doctoral fellow and first author of the study, worked with Dr. Jaberi-Douraki, a corresponding author, and Qi Zhang, a Kansas State University alumnus and current associate professor of mechanical engineering at Yangzhou University in China. Their work examined factors that affect production of large-scale biomass during ultrasonic vibration-assisted pelleting.

The research team developed a computational and mathematical model to determine factors that impact temperature rise during a pelleting process of biomass. The condensed biomass, or pellets, can be easily handled and transported in order to generate ethanol. Ethanol extracted from pellets can substitute for fossil fuels and mitigate accumulation of greenhouse gases.

By studying the entire pelleting process of biomass, the proposed mathematical model determines the key factors and thus delivers a new guideline for pellet production by avoiding unnecessary experiments.

"The model was built based on our solid understanding of physical changes of biomass during the pelleting process," Dr. Shi said. "We then validated the model using experimental studies. By applying the model recommendation to experiments, we found out the percentage of burn-out pellets was reduced. In the meanwhile, the pellet density, pellet durability and sugar yield from pellets were significantly improved."

Dr. Shi explained how bioenergy research has been one of the most active topics in recent years because researchers realized unknown components existed whenever they tried to come up with a new strategy

"At the same time the world is facing severe environmental issues and shortage of fuel supply, this type of research is particularly important for both academia and industry," Dr. Shi said. "Mathematical modeling is a powerful tool because it can save both the time and resources required for experimental studies. By exploring unknown factors during the manufacturing process, this type of work can be further applied to other similar processes with the purpose of predicting biomass production, testing proposed experiments and eventually helping improve decision-making in industry."

The study included support from the Kansas Bioscience Authority. Other collaborative researchers on the publication included Pengfei Zhang with Jiangsu Muyang Holding Co. Ltd., and Zhichao Li with the Department of Industry and System Engineering at North Carolina Agricultural and Technical State University. The experimental work of this study was partially supported by National Science Foundation.

The Institute of Computational Comparative Medicine is an interdisciplinary research-based center established in 2013. Housed in newly built facilities in the College of Veterinary Medicine on the Kansas State University main Manhattan campus, it was created to develop novel tools to quantitatively bridge in vitro experiments to in vivo endpoints and develop methods to extrapolate chemical, drug and nanomaterial behavior across multiple animal species and man.

Drs. Apley and KuKanich speak at K-State Olathe

Drs. Mike Apley and Butch KuKanich
K-State Olathe recently hosted the second seminar in a series on regulatory affairs in animal health. Speakers addressed some of the regulatory challenges that come with new animal health technologies. Talks featuring the CVM's Dr. Mike Apley and Dr. Butch KuKanich (pictured above), among others, looked at the issue from the perspectives of companion animal care, pharmaceutical production, food animal production, federal regulation and more. The next seminar in the series is March 6, 2018. See http://olathe.k-state.edu/regaffairs.

More about that event
The seminar was "Regulatory Challenges Associated with New Technology Implementation" and was held Dec. 7. 

As new technology enters the animal health market, one of the biggest challenges of adaptation is achieving a registration, particularly when some features of the new technology may not clearly fit into the current regulatory processes. 

This seminar is focused on the process of achieving a positive outcome for bringing the new technologies to market and addressing some of the potential regulatory challenges. Rather than regulation being an adversary to new technology, this seminar focuses on ways to work collaboratively with the regulatory agencies to achieve success. 

About the series

Throughout the 2017-2018 academic year, K-State Olathe is hosting four seminars tailored to the Kansas City area animal health regulatory affairs community. The series is aimed at providing hot topic information in regulatory affairs and connecting industry with regulatory agencies. 

#KSUnite

Unity Walk

CVM students, staff, faculty and four-legged friends for participating in #KSUnite, where the K-State family answered a call to action on Nov. 14, 2017. Everyone joined together for the K-State Unity Walk and the KSUnite program to reaffirm who we are, what we value and what we stand for as a university. But we know that the conversation — and more importantly, the work — does not stop there.

Ideas shared during the Nov. 14 facilitated conversations are being gathered and will help guide the K-State community forward. Additionally, the movement invited K-State students, faculty and staff to share ongoing progress with the university community to continue this important work together.
