Producing A Subunit Vaccine For Porcine Epidemic Diarrhea Virus, Zayn Khamis Dec 2016

Producing A Subunit Vaccine For Porcine Epidemic Diarrhea Virus, Zayn Khamis

Electronic Thesis and Dissertation Repository

Porcine epidemic diarrhea virus (PEDv) causes disease and mortality to piglets worldwide. Most vaccines used to combat the disease have been ineffective live attenuated virus vaccines. The goal of this project was to produce a plant-made subunit vaccine based off the membrane protein of the virus. This is the first time this protein has been produced in plants. An elastin-like polypeptide fusion membrane protein accumulated up to 0.8 mg/g of fresh leaf weight when transiently expressed in Nicotiana benthamiana. Virus-like particles were also produced for the first time for PEDv, and were able to form with just the membrane …

Equine arteritis virus (EAV) is the causative agent of equine viral arteritis (EVA), a respiratory, systemic, and reproductive disease of horses and other equid species. Following natural infection, 10–70% of the infected stallions can become persistently infected and continue to shed EAV in their semen for periods ranging from several months to life. Recently, we reported that some stallions possess a subpopulation(s) of CD3+ T lymphocytes that are susceptible to in vitro EAV infection and that this phenotypic trait is associated with long-term carrier status following exposure to the virus. In contrast, stallions not possessing the CD3+ T …

Evaluation Of Several Pre-Clinical Tools For Identifying Characteristics Associated With Limb Bone Fracture In Thoroughbred Racehorses, Anthony Nicholas Corsten Dec 2016

Evaluation Of Several Pre-Clinical Tools For Identifying Characteristics Associated With Limb Bone Fracture In Thoroughbred Racehorses, Anthony Nicholas Corsten

Open Access Theses

Catastrophic skeletal fractures in racehorses are devastating not only to the animals, owners and trainers, but also to the perception of the sport in the public eye. The majority of these fatal accidents are unlikely to be due to chance, but are rather an end result failure from stress fractures. Stress fractures are overuse injuries resulting from an accumulation of bone tissue damage over time. Because stress fractures are pathological, it is possible that overt fractures can be predicted and prevented. In this study, third metacarpals (MC3) from 33 thoroughbred racehorse comprised of 8 non-fractured controls and 25 horses that …

The Impact Of Tickling Rats On Human-Animal Interactions And Rat Welfare, Megan Renee Lafollette Dec 2016

The Impact Of Tickling Rats On Human-Animal Interactions And Rat Welfare, Megan Renee Lafollette

Open Access Theses

Rats initially fear humans which can lead to negative affect, poor welfare, and difficult handling. Also, modeling and measuring positive affect states in rats can pose an additional challenge. Heterospecific play, or “tickling,” is a handling habituation technique that mimics rat rough-and-tumble play that is being used to study positive affect. It can also be used to reduce fear of human, improve welfare, and elicit a positive affect state. However, current studies implementing the technique in laboratory rats use a wide variety of protocols to achieve differential results. Unlike in laboratory environment, pet store rats experience high levels of novelty …

Advanced Biotechnologies For Wildlife Fertility Preservation, Pierre Comizzoli Dec 2016

Advanced Biotechnologies For Wildlife Fertility Preservation, Pierre Comizzoli

The Thai Journal of Veterinary Medicine

Reproductive biotechnologies are critical tools for saving and maintaining endangered species. Some successes have been reported with the use and integration of artificial insemination (with fresh or frozen-thawed semen) in conservation programs. However, not a single species is currently managed through oocyte freezing or embryo-based technologies. This is primarily due to the lack of knowledge of species biology, as well as inadequate facilities, space, expertise, and funding needed for their successful application. More fundamental studies of animal reproductive biology as well as more fertility preservation options are needed with all parties involved (reproductive technologists, zoo biologists and conservationists) adopting parallel …

Regulation Of Alpha-Herpesvirus Reactivation From Latency By Stress, Insun Kook Dec 2016

Regulation Of Alpha-Herpesvirus Reactivation From Latency By Stress, Insun Kook

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

Bovine herpes virus 1 (BHV-1) and Herpes simplex virus 1 (HSV-1) are crucial etiological viral agent of clinical diseases. HSV-1 and BHV-1 establish latent infection in sensory neurons. Periodically, reactivation from latency occurs resulting in virus excretion and transmission. Stress increases corticosteroid levels and the incidence of HSV-1 and BHV-1 reactivation from latency. The synthetic corticosteroid, dexamethasone (DEX) mimics stress and induces BHV-1 and HSV-1 reactivation. However, molecular mechanisms by which corticosteroid mediates viral reactivation are not well understood. My dissertation has focused on elucidating events that induce BHV- 1 or HSV-1 reactivation during the early stages of stress-induced escape …
