Michigan Bovine Tuberculosis Eradication Project: 2007 Activities Report

Michigan Bovine Tuberculosis Bibliography and Database

Bovine tuberculosis (TB) is an infectious disease that is close to being eradicated in the United States, but still poses a significant risk to domestic livestock, wildlife, companion animals, and humans throughout the world. The Michigan Bovine TB Eradication Project involves a multi-agency team of experts from the Michigan departments of Agriculture, Natural Resources and Community Health, Michigan State University, and the US Department of Agriculture.

Assessment Of Biosecurity Procedures To Prevent Bovine Viral Diarrhea Virus Cross Contamination, Rebecca Aden

The Journal of Undergraduate Research

Bovine viral diarrhea virus (BVDV) is a common virus among cattle, and there are many different strains of the virus. BVDV can cause mucosal disease in infected cattle. There are lab strains of BVDV used for testing, but there are also wild-type viruses that may develop within a herd or population. These wild-type strains can be dangerous due to cross contamination between herds. This project compares serum samples from two different herds on the basis of the antibody response to a wild-type virus isolated from a persistent infected animal in one of the herds. We tested for a possible cross …

Risk Factors Associated With The Prevalence Of Tuberculosis-Like Lesions In Fenced Wild Boar And Red Deer In South Central Spain, Joaquin Vicente, Ursula Hofle, Joseba M. Garrido, Isabel G. Fernandez-De-Mera, Pelayo Acevedo, Ramon Juste, Marta Barral, Christian Gortazar

Michigan Bovine Tuberculosis Bibliography and Database

In recent decades the management of large game mammals has become increasingly intensive in south central Spain (SCS), resulting in complex epidemiological scenarios for disease maintenance, and has probably impeded schemes to eradicate tuberculosis (TB) in domestic livestock. We conducted an analysis of risk factors which investigated associations between the pattern of tuberculosis-like lesions (TBL) in wild boar (Sus scrofa) and red deer (Cervus elaphus) across 19 hunting estates from SCS and an extensive set of variables related to game management, land use and habitat structure. The aggregation of wild boar at artificial watering sites was …

Depletion Of 32-Kbp Circular Plasmids From Borrelia Burgdorferi, Amanda Paige Derouen Polito

LSU Master's Theses

The Lyme disease spirochete Borrelia burgdorferi has a very unusual genome composed of one linear chromosome and up to 21 linear and circular plasmids. Several plasmids are known to be important either for mammalian infection or tick colonization. A single spirochete harbors up to 7 different cp32 plasmids; however, nothing is known about their role in mammalian infection. The plasmids in this family are well maintained during in vitro cultivation, making it difficult to study their functions. To effectively deplete the plasmids, an 8kbp fragment containing essential elements for replication and partitioning in B. burgdorferi was amplified from one of …

It has been suggested that T cell immunoglobulin mucin (Tim)-1 expressed on T cells serves to positively costimulate T cell responses. However, crosslinking of Tim-1 by its ligand Tim-4 resulted in either activation or inhibition of T cell responses, thus raising the issue of whether Tim-1 can have a dual function as a costimulator. To resolve this issue, we tested a series of monoclonal antibodies specifi c for Tim-1 and identifi ed two antibodies that showed opposite functional effects. One anti–Tim-1 antibody increased the frequency of antigen-specifi c T cells, the production of the proinfl ammatory cytokines IFN-γ and IL-17, …

Protostrongylid Parasites And Pneumonia In Captive And Wild Thinhorn Sheep (Ovis Dalli), Emily J. Jenkins, A. M. Veitch, Susan J. Kutz, T. K. Bollinger, J. M. Chirino-Trejo, B. T. Elkin, K. H. West, Eric P. Hoberg, L. Polley

Harold W. Manter Laboratory of Parasitology: Faculty Publications

We describe health significance of protostrongylid parasites (Parelaphostrongylus odocoilei and Protostrongylus stilesi) and other respiratory pathogens in more than 50 naturally infected Dall’s sheep (Ovis dalli dalli) from the Mackenzie Mountains, Northwest Territories (1998–2002) as well as in three Stone’s sheep (O. d. stonei) experimentally infected with P. odocoilei (2000–2002). Histological lesions in the brain and distribution of P. odocoilei in the muscles of experimentally and naturally infected sheep were consistent with a previously hypothesized ‘‘central nervous system to muscle’’ pattern of migration for P. odocoilei. Dimensions of granulomas associated with eggs of …

Chlorophacinone Baiting For Belding’S Ground Squirrels, Craig A. Ramey, George H. Matschke, Richard M. Engeman

United States Department of Agriculture Wildlife Services: Staff Publications

The efficacy of using 0.01% chlorophacinone on steam-rolled oat (SRO) groats applied in CA alfalfa by spot-baiting/hand baiting around burrow entrances (~11.5 g) to control free-ranging Belding's ground squirrels (Spermophilus beldingi) were compared in 6 randomly assigned square treatment units (TUs). Four TUs were given the rodenticide and 2 treated with placebo bait. Each TU was a 0.4 ha square surrounded by a similarly treated 5.5 ha square buffer zone. Baits were applied on May 13 and re-applied, on May 20 and May 22, after 7 days of un-forecasted cool wet weather greatly reduced their above ground activity. Pesticide (EPA …

Tracing The Origin Of The Recent Rise In Neuropathogenic Ehv-1, Kathryn Laura Smith

University of Kentucky Master's Theses

Equine herpesvirus type-1(EHV-1) is a complex virus known for inducing various forms of disease in horses. In recent years, the number of cases of neurological disease caused by this virus has increased. While there are a number of possible sources for this recent surge, this project set out to determine if a genotypic shift in the latent population of the virus in favor of the neuropathogenic form of EHV-1 is the basis for the recent increase in frequency of EHV-1 neurologic disease. To ascertain if such a shift has in fact occurred, 450 EHV-1 isolates were obtained from fetal tissues …

Brucella Melitensis: The Evaluation Of A Putative Hemagglutinin Gene's Effect On Virulence In The Caprine Model, Quinesha Laticia Perry

LSU Doctoral Dissertations

Brucella melitensis is a facultative intracellular bacterial pathogen that causes abortions in goats and sheep and Malta fever in humans. The zoonotic disease brucellosis causes severe economic losses in the Mediterranean region and parts of Africa, Asia, and Latin America. With the completion of the genomic sequences of B. abortus 2308 and B. melitensis 16M, no classical virulence factors were found; and the chromosomes were virtually identical. However, in B. melitensis, a putative hemagglutinin gene was identified which is absent in B. abortus. The possibility of the hemagglutinin gene being a potential virulence factor was evaluated via gene replacement/deletion in …

Transfusion-Associated Transmission Of West Nile Virus, United States 2003 Through 2005, Susan P. Montgomery, Jennifer A. Brown, Matthew Kuehnert, Theresa L. Smith, Nicholas Crall, Robert S. Lanciotti, Alexandre Macedo De Oliveira, Thomas Boo, Anthony A. Marfin, 2003 West Nile Virus Transfusion-Associated Transmission Investigation Team

Zoonotics and Wildlife Disease: Publications

BACKGROUND: National blood donation screening for West Nile virus (WNV) started in June 2003, after the documentation of WNV transfusion-associated transmission (TAT) in 2002.

STUDY DESIGN AND METHODS: Blood donations were screened with investigational nucleic acid amplification assays in minipool formats. Blood collection agencies (BCAs) reported screening results to state and local public health authorities. Donor test results and demographic information were forwarded to CDC via ArboNET, the national electronic arbovirus surveillance system. State health departments and BCAs also reported suspect WNV TATs to CDC, which investigated these reports to confirm WNV infection in blood transfusion recipients in the absence …

Bovine Immune Response To Shiga-Toxigenic Escherichia Coli O157:H7., Mark A Hoffman, Christian Menge, Thomas A Casey, William Laegreid, Brad T Bosworth, Evelyn A Dean-Nystrom

Manuscripts, Articles, Book Chapters and Other Papers

Although cattle develop humoral immune responses to Shiga-toxigenic (Stx+) Escherichia coli O157:H7, infections often result in long-term shedding of these human pathogenic bacteria. The objective of this study was to compare humoral and cellular immune responses to Stx+ and Stx- E. coli O157:H7. Three groups of calves were inoculated intrarumenally, twice in a 3-week interval, with different strains of E. coli: a Stx2-producing E. coli O157:H7 strain (Stx2+ O157), a Shiga toxin-negative E. coli O157:H7 strain (Stx- O157), or a nonpathogenic E. coli strain (control). Fecal shedding of Stx2+ O157 was significantly higher than that of Stx- O157 or the …

Anti-Capsular Antibodies Activate Killing Of Escherichia Coli O8:K87 By The Alternate Complement Pathway In Porcine Serum, N. M. Clark, E. M. Berberov, M. Wang, Rodney A. Moxley

School of Veterinary and Biomedical Sciences: Faculty Publications

Enterotoxigenic Escherichia coli (ETEC) strains that produce K88 (F4) ⁺ fimbria are important causes of diarrhea and post-diarrheal septicemia in swine. ETEC O8:K87, a serotype represented by a number of these strains, is typically serum resistant. Strain-specific antibodies are known to activate alternative C pathway-mediated killing of other serum-resistant E. coli [Hill, A.W., Shears, A.L., Hibbitt, K.G., 1978. The requirement of specific antibody for the killing of E. coli by the alternate complement pathway in bovine serum. Immunology 34, 131–136], but their antigenic targets have not been determined. We tested the hypothesis that anti-K87 antibodies activate alternative pathway-mediated killing of …

Development Of A Gis-Based, Real-Time Internet Mapping Tool For Rabies Surveillance, Jesse D. Blanton, Arie Manangan, Jamie Manangan, Cathleen A. Hanlon, Dennis Slate, Charles E. Rupprecht

Zoonotics and Wildlife Disease: Publications

Background: Oral rabies vaccination programs have been implemented to control the spread of wildlife rabies in the United States. However, current surveillance systems are inadequate for the efficient management and evaluation of these large scale vaccine baiting programs. With this in mind, a GIS-based rabies surveillance database and Internet mapping application was created. This surveillance system, RabID, provides a new resource for the rapid mapping and dissemination of data on animal rabies cases in relation to unaffected, enzootic, and baited areas where current interventions are underway.

Results: RabID is a centralized database for diagnostic and demographic information collected by local, …

Sub-Typing Of Prrsv Isolates By Means Of Measurement Of Cross-Neutralization Reactions, Fernando A. Osorio

School of Veterinary and Biomedical Sciences: Faculty Publications

The degree of similitude or closeness between two different isolates or strains of PRRSV is very important for deciding which strains should be used for immunization, by either vaccinating with commercial vaccines or attempting to stabilize a herd with planned wt PRRSV infection. As previously known for certain important viral diseases, such as in Foot and Mouth Disease, the reciprocal (cross-) neutralization titers between two strains may be of utmost importance to establish the degree of similarity or difference between these. There is currently a void of methods that would allow distinguishing or grouping strains of PRRSV in a manner …

Detection Of Panulirus Argus Virus 1 (Pav1) In The Caribbean Spiny Lobster Using Fluorescence In Situ Hybridization (Fish), Caiwen Li, Jeffrey D. Shields, Hamish J. Small, Kimberly S. Reece, Carmony L. Hartwig, Roland A. Cooper, Robert E. Ratzlaff

Biological Sciences Faculty Publications

Panulirus argus Virus 1 (PaV1) is the first virus known to be pathogenic to a wild lobster. It infects the Caribbean spiny lobster P. argus from the Florida Keys, and has a predilection for juveniles. The monitoring of the virus in wild populations and study of its behavior in the laboratory require the development of reliable diagnostic tools. A sensitive and specific fluorescence in situ hybridization (FISH) assay was developed for detection of PaV1. The lower detection limit using a 110 bp DNA probe in a dot-blot hybridization for PaV1 DNA was 10 pg of cloned template PaV1 DNA and …

Disease Risks Associated With Increasing Feral Swine Numbers And Distribution In The United States, Thomas Hutton, Thomas J. Deliberto, Sheldon Owen, Bruce Morrison

Michigan Bovine Tuberculosis Bibliography and Database

Feral hogs or “wild boars” come from several sources and include released or escaped domestic swine and the truly wild European boar. When free-roaming in North America, all are included in the term “feral swine,” as are hybrids of the two types. Although morphologically distinct, both the feral swine and European wild swine are recognized as Sus scrofa. The physical damage caused by feral swine has been well documented and includes damage to vehicles, vineyards, tree plantings, archaeological sites, agricultural crops, turf, soils, rare plant communities, and wildlife habitat (Seward et al. 2004). In addition they compete with livestock …

Visualization Of Intracellular Transport Of Vesicular Stomatitis Virus Nucleocapsids In Living Cells, Subash C. Das, Debasis Nayak, You Zhou, Asit K. Pattnaik

School of Veterinary and Biomedical Sciences: Faculty Publications

The phosphoprotein (P) of vesicular stomatitis virus (VSV) is a subunit of the viral RNA polymerase. In previous studies, we demonstrated that insertion of 19 amino acids in the hinge region of the protein had no significant effect on P protein function. In the present study, we inserted full-length enhanced green fluorescent protein (eGFP) in frame into the hinge region of P and show that the fusion protein (PeGFP) is functional in viral genome transcription and replication, albeit with reduced activity. A recombinant vesicular stomatitis virus encoding PeGFP in place of the P protein (VSV-PeGFP), which possessed reduced growth kinetics …

Avian Influenza: Trade Issues, Toby Moore, Nancy Morgan

Zoonotics and Wildlife Disease: Publications

In 2003, an outbreak of a highly pathogenic H5N1 strain of avian influenza (AI) in Southeast Asia, notably in Vietnam but also in Thailand, focused extensive local and international media coverage on the disease and its potential human health consequences. The media coverage has followed subsequent AI outbreaks in the People’s Republic of China, the Republic of Korea, and Japan, and westward through Russia into Eastern Europe and the Middle East. Health officials remain on alert because the virus has crossed the species barrier, causing more than 100 human deaths over the last 2 years. Other deaths, most recently in …

Transcriptome Signature Of Virulent And Attenuated Pseudorabies Virus-Infected Rodent Brain, Christina Paulus, Patricia J. Sollars, Gary E. Pickard, Lynn W. Enquist

School of Veterinary and Biomedical Sciences: Faculty Publications

Mammalian alphaherpesviruses normally establish latent infections in ganglia of the peripheral nervous system in their natural hosts. Occasionally, however, these viruses spread to the central nervous system (CNS), where they cause damaging, often fatal, infections. Attenuated alphaherpesvirus derivatives have been used extensively as neuronal circuit tracers in a variety of animal models. Their circuit-specific spread provides a unique paradigm to study the local and global CNS response to infection. Thus, we systematically analyzed the host gene expression profile after acute pseudorabies virus (PRV) infection of the CNS using Affymetrix GeneChip technology. Rats were injected intraocularly with one of three selected …

The Cattle Industry's Guidelines For The Care And Handling Of Cattle

Nebraska Beef Quality Assurance Program

Cattlemen have long recognized the need to properly care for livestock. Sound animal husbandry practices, based on decades of practical experience and research, are known to impact the wellbeing of cattle, individual animal health and herd productivity. Cattle are produced in very diverse environments and geographic locations in the United States. There is not one specific set of production practices that can be recommended for all cattle producers. Personal experience, training and professional judgment can serve as a valuable resource for providing proper animal care.

Zoonotics and Wildlife Disease: Publications

The remarkable mammals known as “bats” and “flying foxes” (order Chiroptera [“hand wing”]) may be the most abundant, diverse, and geographically dispersed vertebrates (Table 1). Although a great deal is known about them, detailed information is needed to explain the astonishing variations of their anatomy, their lifestyles, their roles in ecosystems ecology, and their importance as reservoir hosts of viruses of proven or potential significance for human and veterinary health.

PrpSc Accumulation In Fetal Cotyledons Of Scrapieresistant Lambs Is Influenced By Fetus Location In The Uterus, Janet Alverson, Katherine I. O'Rourke, Timothy V. Baszler

Zoonotics and Wildlife Disease: Publications

Placentae from scrapie-infected ewes have been shown to accumulate PrP^Sc when the genotype of the fetus is of a susceptible genotype (VRQ/VRQ, ARQ/VRQ or ARQ/ARQ). Cotyledons from fetuses of genotypes ARR/ARR, ARQ/ARR and ARQ/VRR have previously been shown to be resistant to PrP^Sc accumulation. By using ewes from a naturally infected scrapie flock, cotyledons from fetuses of multiple births of different genotypes were examined. PrP^Sc was detected in fetal cotyledons of genotype ARQ/ARQ, but not in cotyledons from their dizygotic twin of genotype ARQ/ARR. This confirms earlier reports of single fetuses of these genotypes, but is the …

Comparison Of Two Automated Immunohistochemical Procedures For The Diagnosis Of Scrapie In Domestic Sheep And Chronic Wasting Disease In North American White-Tailed Deer (Odocoileus Virginianus) And Mule Deer (Odocoileus Hemionus), T. V. Baszler, M. Kiupel, E. S. Williams, B. V. Thomsen, T. Gidlewski, D. L. Montgomery, Katherine I. O'Rourke, S. M. Hall

Zoonotics and Wildlife Disease: Publications

Two commercially available automated immunohistochemistry platforms, Ventana NexES and DakoCytomation Autostainer Universal Staining System, were compared for diagnosing sheep scrapie and cervid chronic wasting disease. Both automated platforms used the same antiprion protein monoclonal primary antibodies, but different platform-specific linker and amplification reagents and procedures. Duplicate sections of brainstem (at the level of the obex) and lymphoid tissue (retropharyngeal lymph node or tonsil) from the same tissue block were immunostained for the comparison. Examination of 1,020 tissues from 796 sheep revealed 100% concordance of results between the Ventana NexES and DakoCytomation platforms for diagnosing sheep scrapie from lymphoid tissue (103/103 …
