Development of a Subunit Vaccine Against Bovine Diarrhea Caused by K99 Enterotoxigenic Escherichia coli and Bovine Viral Diarrhea Virus
… strains expressing K99 (F5) fimbriae and heat-stable type I (STa) enterotoxin is the predominant bacterial cause of diarrhea in calves; whereas bovine viral diarrhea virus (BVDV) causes diarrhea and other illness to cattle at all ages. A vaccine that prevents against both K99 fimbrial …

Investigation of Swine Influenza Virus Genetic Diversity and Evolution
… A exists primarily in a waterfowl reservoir and readily infects numerous avian and mammalian species. In swine, numerous subtypes and antigenic lineages of swine influenza virus (SIV) co-circulate. The reassortment of viral RNA segments in cells infected by multiple viruses can lead to a …

Characterization of Shiga-toxin Producing Escherichia coli Infections and Cryptosporidiosis in South Dakota with Respect to Animal Exposures, 2012
… 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 direct contact with …

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
… 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 polymerase …

Molecular Diagnosis and Anthelmintic Control of Trichostrongyle and Toxicara nematodes in Bison bison Herds from the U.S.A. Central Great Plains
… 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 nematodes common to bison herds. This study determined the prevalence and …

Development of a Fluorescence Microsphere Immunoassay for Detection of PRRSV Infection Using Oral Fluid Samples as an Alternative to Serum-based Assays
<p>Porcine reproductive and respiratory syndrome virus (PRRSV) continues to be one of the most devastating diseases in the swine industry throughout the world. PRRSV has caused the swine industry more than $600 million a year. PRRSV causes late term abortions, infertility, and severe respiratory …

Recombinant Protein Production in Bacillus Species, Isolation and Methionine Production in Methionine-producing Microorganisms
… 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 biotransformation of LA using microbial cells and enzymes. However, the evaluation of these strains suggest that growth …

The Indirect Effect of BVDV on Immune Suppression: The Role of Infected Macrophages in Lymphocyte Apoptosis
… 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 understood. In this in vitro …
