Surveillance Of Selected Diseases In Free-Ranging Elk (Cervus Elaphus Nelsoni) In Nebraska, 1995-2009, Michael A. Cover, Scott E. Hygnstrom, David W. Oates, Kit M. Hams, Kurt C. Vercauteren

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Sera samples were collected from 21 free-ranging, captured female elk (Cervus elaphus nelsoni) in 1995- 96, and tissue and sera samples were collected from 415 hunter-harvested elk from 1995 to 2006 and tested for selected diseases. Titers for Anaplasma marginale were detected in 81 of 436 (19%) elk. Occurrence of antibodies to anaplasmosis increased from 4 to 40 elk from 2002 to 2006. Titers for bovine viral diarrhea virus (BVDV) were detected in 18 of 346 (5%) samples. Titers for Leptospira interrogans serovars were detected in 21 of 289 (7%) of samples from 1995 to 2004. Titers for …

Caring For Compromised Cattle: Assessing Animals At Risk

Nebraska Beef Quality Assurance Program

Cattlemen have long recognized the need to properly care for their livestock. Sound animal husbandry practices – based on research and decades of practical experience – are known to impact the well-being of cattle, individual animal health and herd productivity. There is no doubt that producers work hard to ensure that their cattle are properly cared for throughout all stages of production. Unfortunately, it’s a fact of raising cattle that some animals will become injured to the extent that they are unable to stand or walk without assistance.

Assessor’S Guide To A Beef Quality Assurance Cow-Calf Assessment

Nebraska Beef Quality Assurance Program

The BQA Cow-Calf Assessment is an on-site educational tool that allows for assessing and benchmarking key indicators of animal care and well-being as well as operational conditions. The Cow-Calf Assessment focuses on three main areas – Animals, Records and Best Management Practices (BMP), and Facilities and Equipment.

Evaluation Of Mass Spectrometric Methods For Detection Of The Anti-Protozoal Drug Imidocarb, A. F. Lehner, J. A. Hitron, J. May, C. Hughes, R. Eisenberg, N. Schwint, D. P. Knowles, P. Timoney, Thomas Tobin

Maxwell H. Gluck Equine Research Center Faculty Publications

Imidocarb [N,N'-bis[3-(4,5-dihydro-1H-imidazol-2-yl)phenyl]urea, C₁₉H₂₀N₆O₁, m.w. 348.41] is a symmetrical carbanilide derivative used to treat disease caused by protozoans of the Babesia genus. Imidocarb, however, is also considered capable of suppressing Babesia-specific immune responses, allowing Babesia-positive horses to pass a complement fixation test (CFT) without eliminating the infection. This scenario could enable Babesia-infected horses to pass CFT-based importation tests. It is imperative to unequivocally identify and quantify equine tissue residues of imidocarb by mass spectrometry to address this issue. As a pretext to development of sensitive tissue assays, we have investigated possibilities of mass …

Regulation Of The Latency–Reactivation Cycle By Products Encoded By The Bovine Herpesvirus 1 (Bhv-1) Latency-Related Gene, Clinton Jones, Leticia Frizzo Da Silva, Devis Sinani

School of Veterinary and Biomedical Sciences: Faculty Publications

Like other α-herpesvirinae subfamily members, the primary site for bovine herpesvirus 1 (BHV-1) latency is ganglionic sensory neurons. Periodically BHV-1 reactivates from latency, virus is shed, and consequently virus transmission occurs. Transcription from the latency-related (LR) gene is readily detected in neurons of trigeminal ganglia (TG) of calves or rabbits latently infected with BHV-1. Two micro-RNAs and a transcript encompassing a small open reading frame (ORF-E) located within the LR promoter can also be detected in TG of latently infected calves. A BHV-1 mutant that contains stop codons near the beginning of the first open reading frame (ORF2) within the …

Development, Optimization, And Validation Of A Classical Swine Fever Virus Real-Time Reverse Transcription Polymerase Chain Reaction Assay, August J. Eberling, Jill Bieker-Stefanelli, Monica M. Reising, David Siev, Barbara M. Martin, Michael T. Mcintosh, Tammy R. Beckham

Zoonotics and Wildlife Disease: Publications

Classical swine fever (CSF) is an economically devastating disease of pigs. Instrumental to the control of CSF is a well-characterized assay that can deliver a rapid, accurate diagnosis prior to the onset of clinical signs. A real-time fluorogenicprobe hydrolysis (TaqMan) reverse transcription polymerase chain reaction (RT-PCR) for CSF was developed by the United States Department of Agriculture (USDA) at the Plum Island Animal Disease Center (CSF PIADC assay) and evaluated for analytical and diagnostic sensitivity and specificity. A well-characterized panel including Classical swine fever virus (CSFV), Bovine viral diarrhea virus (BVDV), and Border disease virus (BDV) isolates was utilized in …
