Diphyllobothrium Fayi N. Sp. (Cestoda: Diphyllobothriidae) From The Pacific Walrus, Odobenus Rosmarus Divergens, Robert L. Rausch Jul 2005

Diphyllobothrium Fayi N. Sp. (Cestoda: Diphyllobothriidae) From The Pacific Walrus, Odobenus Rosmarus Divergens, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

An independent species of cestode of the genus Diphyllobothrium Cobbold, 1858, known only from the Pacific walrus, Odobenus rosmarus divergens Illiger, has been incorrectly designated Diphyllobothrium cordatum (Leuckart, 1863) in the literature since 1955. That cestode is described in this study as Diphyllobothrium fayi n. sp. on the basis of specimens obtained from walruses from the northern Bering Sea and the Arctic Ocean. It is distinguished readily from D. cordatum by its much larger strobila of different form and by a range of morphological characteristics of taxonomic significance in the reproductive organs. Comparisons were made with specimens of D. cordatum …

Oral Rabies Vaccination—A Progress Report, Dennis Slate, Charles Rupprecht, Mike Dunbar, Robert Mclean Jun 2005

Oral Rabies Vaccination—A Progress Report, Dennis Slate, Charles Rupprecht, Mike Dunbar, Robert Mclean

United States Department of Agriculture Wildlife Services: Staff Publications

Oral rabies vaccination (ORV) targeting specific wild Carnivora species has emerged as an integral adjunct to conventional rabies control strategies to protect humans and domestic animals. ORV has been applied with progress toward eliminating rabies in red foxes (Vulpes vulpes) in western Europe and southern Ontario, Canada. Beginning in the 1990’s, coordinated ORV was implemented in Texas to contain and eliminate variants of rabies virus in the gray fox (Urocyon cinereoargenteus ) and coyote (Canis latrans ) and in several eastern U.S. States with the goal of preventing spread of raccoon (Procyon lotor ) rabies. …

Preliminary Serologic Survey Of Selected Diseases And Movements Of Feral Swine In Texas, A. Christy Wyckoff, Scott E. Henke, Tyler Campbell, David G. Hewitt, Kurt C. Vercauteren Jun 2005

Preliminary Serologic Survey Of Selected Diseases And Movements Of Feral Swine In Texas, A. Christy Wyckoff, Scott E. Henke, Tyler Campbell, David G. Hewitt, Kurt C. Vercauteren

United States Department of Agriculture Wildlife Services: Staff Publications

Feral swine (Sus scrofa) populations occur throughout eastern, central, and southern Texas, and their populations appear to be increasing. Despite their abundance and wide distribution, little is known about their range and interaction with domestic animals. In the last decade the national pork production industry has enforced an eradication program for economically detrimental swine diseases such as pseudorabies and brucellosis. It is hypothesized that feral hogs can be reservoirs that could reintroduce diseases to disease-free domestic swine herds. The objectives of this on-going project are to determine the prevalence of selected swine diseases that exist within feral hog …

Michigan Bovine Tuberculosis Bibliography and Database

Despite having a very low incidence of disease, reindeer (Rangifer tarandus) are subject to tuberculosis (TB) testing requirements for interstate shipment and herd accreditation in the United States. Improved TB tests are desperately needed, as many reindeer are falsely classified as reactors by current testing procedures. Sera collected sequentially from 11 (experimentally) Mycobacterium bovis-infected reindeer and 4 noninfected reindeer were evaluated by enzyme-linked immunosorbent assay (ELISA), immunoblotting, and multiantigen print immunoassay (MAPIA) for antibody specific to M. bovis antigens. Specific antibody was detected as early as 4 weeks after challenge with M. bovis. By MAPIA, sera …

United States Department of Agriculture Wildlife Services: Staff Publications

Sera from white-tailed deer (Odocoileus virginianus) were collected in Iowa during the winter months (1999-2003), 2 years before and after West Nile virus (WNV) was first reported in Iowa (2001), and were analyzed for antibodies to WNV. Samples from 1999 to 2001 were antibody negalive by blocking enzyme-linikedI immunosorbent assay (bELISA) and plaque reduction neutralization test (PRNT90). Prevalence derived from bELISA (2002, 12.7%; 2003. 11.2%) and WNV PRNT90 (2002,7.9%; 2003, 8.5%) assays were similar. All sanlples were negative for antibodies against St. Louis encephalitis virus as determined by PRNT90. Antibodies to flaviviruses were …

Fence-Line Interactions Among Farmed And Free-Ranging Cervids: Preliminary Results, Kurt C. Vercauteren, Justin W. Fischer, Robert Pooler, Michael J. Lavelle, Greg Phillips

United States Department of Agriculture Wildlife Services: Staff Publications

Occurrences of disease outbreaks within and near captive cervid (mule deer (Odocoileus hemionus), white-tailed deer (Odocoileus virginianus), and Rocky Mountain elk (Cervus elaphus nelsoni)) farms have recently drawn attention to these facilities. Some state wildlife and agricultural agencies have pondered making double fencing mandatory or otherwise increasing regulation of captive operations. Diseases such as Chronic Wasting Disease (CWD) and Bovine Tuberculosis (bovine TB) are a threat to captive and free-ranging cervid populations. Concerns over these and other diseases being transmitted from captive to wild cervids, and vice versa, have increased. In most cases, captive …

Functional Mimicry Of A Human Immunodeficiency Virus Type 1 Coreceptor By A Neutralizing Monoclonal Antibody, Shi-Hua Xiang, Michael Farzan, Zhihai Si, Navid Madani, Liping Wang, Eric Rosenberg, James Robinson, Joseph Sodroski May 2005

Functional Mimicry Of A Human Immunodeficiency Virus Type 1 Coreceptor By A Neutralizing Monoclonal Antibody, Shi-Hua Xiang, Michael Farzan, Zhihai Si, Navid Madani, Liping Wang, Eric Rosenberg, James Robinson, Joseph Sodroski

Nebraska Center for Virology: Faculty Publications

Interaction of the human immunodeficiency virus type 1 (HIV-1) gp120 envelope glycoprotein with the primary receptor, CD4, promotes binding to a chemokine receptor, either CCR5 or CXCR4. The chemokine receptor-binding site on gp120 elicits CD4-induced (CD4i) antibodies in some HIV-1-infected individuals. Like CCR5 itself, the CD4i antibody 412d exhibits a preference for CCR5-using HIV-1 strains and utilizes sulfated tyrosines to achieve binding to gp120. Here, we show that 412d binding requires the gp120 β19 strand and the base of the V3 loop, elements that are important for the binding of the CCR5 N terminus. Two gp120 residues in the V3 …

Tularemia: Emergence/Re-Emergence, Jeannine M. Petersen, Martin E. Schriefer Apr 2005

Tularemia: Emergence/Re-Emergence, Jeannine M. Petersen, Martin E. Schriefer

Zoonotics and Wildlife Disease: Publications

Francisella tularensis is a gram-negative coccobacillus and the etiologic agent of the zoonotic disease tularemia. First described in 1911 in Tulare County, California, it has since been reported throughout the Northern Hemisphere, with natural infections reported among an unusually wide range of vertebrates and invertebrates. In recent years, tularemia has emerged in new geographic locations, populations, and settings. This review will serve to highlight mechanisms contributing to the recent emergence of tularemia as well as a repertoire of diagnostic tools useful for detecting and diagnosing disease.

Papers in Biochemical Engineering

Human hookworm infection is a major cause of anemia and malnutrition in the developing world. In an effort to control hookworm infection, the Human Hookworm Vaccine Initiative has identified candidate vaccine antigens from the infective larval stage (L3) of the parasite, including a family of pathogenesis related- 1 (PR-1) proteins known as the ancylostoma-secreted proteins (ASPs). The functions of the ASPs are unknown. In addition, it is unclear why some ASPs have one while others have multiple PR-1 domains. There are no known structures of a multi-domain ASP and in an effort to remedy this situation, recombinant Na …

Electrocution Of An Adult White-Tailed Deer, Christopher S. Deperno, Benjamin J. Bigalke, Jonathan A. Jenks, Brian S. Haroldson, Robert G. Osborn

The Prairie Naturalist

On 16 May 2002, an adult female white-tailed deer (Odocoileus virginianus) died after becoming entangled in an electric fence in southeast Minnesota. The deer (#393) was captured 30 January 2000 as part of a cooperative, long-term deer mortality study being conducted in southern Minnesota (Bigalke et al. 2002, Brinkman 2003, Brinkman et al. 2002). Although fence entanglements occur, they do not account for significant losses in white-tailed deer populations (Matschke et al. 1984). Nixon et al. (1991) documented mortality of two fawns with broken cervical vertebrae that had collided with fences, but did not distinguish the type of …

5-Ht1b Receptor-Mediated Presynaptic Inhibition Of Gaba Release In The Suprachiasmatic Nucleus, Jayne R. Bramley, Patricia J. Sollars, Gary E. Pickard, F. Edward Dudek Feb 2005

5-Ht1b Receptor-Mediated Presynaptic Inhibition Of Gaba Release In The Suprachiasmatic Nucleus, Jayne R. Bramley, Patricia J. Sollars, Gary E. Pickard, F. Edward Dudek

School of Veterinary and Biomedical Sciences: Faculty Publications

The suprachiasmatic nucleus (SCN) receives a dense serotonergic innervation that modulates photic input to the SCN via serotonin 1B (5-HT1B) presynaptic receptors on retinal glutamatergic terminals. However, the majority of 5-HT1B binding sites in the SCN are located on nonretinal terminals and most axonal terminals in the SCN are GABAergic. We therefore tested the hypothesis that 5-HT1B receptors might also be located on SCN GABAergic terminals by examining the effects of the highly selective 5-HT1B receptor agonist CP-93,129 on SCN miniature inhibitory postsynaptic currents (mIPSCs). Whole cell patch-clamp recordings of mIPSCs were obtained from rat …

Harold W. Manter Laboratory of Parasitology: Library Materials

The high prevalence of Duffy negativity (lack of the Duffy blood group antigen) among human populations in sub-Saharan Africa has been used to argue that Plasmodium vivax originated on that continent. Here, we investigate the phylogenetic relationships among 10 species of Plasmodium that infect primates by using three genes, two nuclear (β-tubulin and cell division cycle 2) and a gene from the plastid genome (the elongation factor Tu). We find compelling evidence that P. vivax is derived from a species that inhabited macaques in Southeast Asia. Specifically, those phylogenies that include P. vivax as an ancient lineage from …

Post-Harvest Interventions To Reduce/Eliminate Pathogens In Beef, M. Koohmaraie, T. M. Arthur, J. M. Bosilevac, M. Guerini, S. D. Shackelford, T. L. Wheeler

Roman L. Hruska U.S. Meat Animal Research Center: Reports

In 1999 the foodborne pathogens Salmonella, Listeria, Campylobacter, and Escherichia coli (both O157 and non-O157) were estimated to cause more than 6 million illnesses and approximately 9000 deaths each year. However, the most recent Centers for Disease Control and Prevention report on the sources and incidence of foodborne disease, released in 2004, has shown a dramatic decrease in E. coli O157:H7 infections. Since raw beef products are the most frequently foodborne sources of these pathogens, the results of this report demonstrate that the microbiological quality of raw beef has improved greatly. During the intervening years, post-harvest interventions have continually …
