Reagents and Tools to Identify Epizootic Hemorrhagic Disease Virus-2
<p>The purpose of this project was to define monoclonal antibodies against viral proteins from Epizootic Hemorrhagic Disease Virus (EHDV) to be used in quality control of vaccines produced by an industrial partner, and development of tools to identify EHDV. EHDV is an Orbivirus, which also includes …

Characterization of Shiga-toxin Producing Escherichia coli Infections and Cryptosporidiosis in South Dakota with Respect to Animal Exposures, 2012
<p>Shiga-toxin producing strains of <em>Escherichia coli</em> (STEC) and <em>Cryptosporidium</em> spp. are significant causes of illness in humans. Incidence rates of these illnesses are higher in South Dakota than in the United States as a whole. Transmission of these agents to people through …

Using Genetic and Pathogeneses Studies to Develop Antiviral and BVDV Vaccine Targets
<p>Understanding bovine viral diarrhea virus (BVDV) interaction with the host may help explain the ability of the virus to cause multiple forms of disease ranging from subclinical symptoms to severe disease and even death. BVDV cytopathogenicity and onset of mucosal disease within one herd of PI …

Influenza Viral Protein Interaction Detecting Methods Development and A.M1-host Interplay Network Investigation
<p>The viral RNA-dependent RNA polymerases of influenza A and B are trimetric complexes (PA, PB1, and PB2 subunits), and are crucial for both transcription and replication of the viral genome. While there are extensive data on the structure and function of influenza A polymerase, the influenza B …

Molecular Diagnosis and Anthelmintic Control of Trichostrongyle and Toxicara nematodes in Bison bison Herds from the U.S.A. Central Great Plains
<p>Bison producers face many challenges, including the transmission of parasitic diseases such as trichostrongylosis and toxocariasis into and within their herds. These diseases can reduce animal production and cause occasional death. There have been no surveys to identify gastrointestinal …

Development and Characterization of A Recombinant Orf Virus Vector Expressing the Spike Protein of Porcine Epidemic Diarrhea Virus
… as a vaccine delivery vector for use in veterinary medicine. Here we explored the potential of ORFV as a vaccine delivery vector for use in swine. The spike (S) protein of porcine epidemic diarrhea virus (PEDV) was used as our model antigen and the immunogenicity and protective efficacy …

Senecavirus A: Epidemiology, Pathogenesis and Infection Dynamics
<p>Senecavirus A (SVA) is a positive sense single-stranded virus that belongs to the genus <em>Senecavirus</em> within the family <em>Picornaviridae</em>. Senecavirus has been present in US swine population since 1988. However, there have been only a few reports of SVA associated with disease in …

Intranasal Immunization of Pigs with Porcine Reproductive and Respiratory Syndrome Virus like Particles Plus 2’, 3’ –cGamp Vaccigrade™ Adjuvant Exacerbates Viremia After Virus Challenge
<p>Porcine reproductive and respiratory syndrome virus (PRRSV) is an economically devastating virus that causes a persistent infection and spreads quickly. The virus causes abortions in sows and respiratory diseases in young piglets. Current PRRSV vaccines appear to provide limited …

Surveillance of Emerging Livestock Viruses
<p>Accurate and rapid diagnostic tests are essential for the management and control of emerging infectious diseases. Therefore, the overall goals of studies presented in this dissertation were to provide improved diagnostic and surveillance capabilities for several emerging viral diseases impacting …

Recombinant Protein Production in Bacillus Species, Isolation and Methionine Production in Methionine-producing Microorganisms
<p>Linoleic acid isomerase (LAI) is the enzyme that converts linoleic acid to conjugated linoleic acids (CLAs) which appear to be capable of lowering cancer risk and enhancing immunity. There is an interest in developing commercial processes for the production of single isomers of CLA by …

The Indirect Effect of BVDV on Immune Suppression: The Role of Infected Macrophages in Lymphocyte Apoptosis
<p>BVDV is an important pathogen of cattle that affects both the dairy and beef industry causing severe economic losses. The main problem of BVDV is the immune suppression that is associated with lymphoid depletion shortly post infection. The mechanism of this immune suppression is not well …

Characterising variation in the gene for the Dichelobacter nodosus Type IV fimbrial protein: Development of a molecular typing system
… in commercial footrot vaccines (Mallinckrodt Veterinary Ltd), is described. The rimA sequences exhibited varying degrees (89-100%) of homology to the prototype Australian strains (Mattick et ai., 1991). Serotype B sequences of New Zealand origin showed the greatest variation at the protein …

Characterization of the Swine Gut Microbiome Dynamics, Culturomics and Probiotics
<p>The gastrointestinal tract is a critical place where the immune system concentrates many of its protective functions. It exerts both physical and biochemical defenses against invading foodborne pathogens and other hazards. In pigs, the gut microbiota community assembled postnatal plays a very …

Understanding the Effect of BVDV on Innate Immune Response of Neutrophils
<p>Bovine viral diarrhea virus (BVDV) is one of the highly prevalent and economically important diseases of cattle industry worldwide. The two major consequences of this disease are persistent infection and immunosuppression. Several studies have been done to determine the underline mechanisms of …
