Equine Protozoal Myeloencephalitis: An Updated Consensus Statement With A Focus On Parasite Biology, Diagnosis, Treatment, And Prevention, S. M. Reed, M. Furr, Daniel K. Howe, A. L. Johnson, R. J. Mackay, J. K. Morrow, N. Pusterla, S. Witonsky

Veterinary Science Faculty Publications

Equine protozoal myeloencephalitis (EPM) remains an important neurologic disease of horses. There are no pathognomonic clinical signs for the disease. Affected horses can have focal or multifocal central nervous system (CNS) disease. EPM can be difficult to diagnose antemortem. It is caused by either of 2 parasites, Sarcocystis neurona and Neospora hughesi, with much less known about N. hughesi. Although risk factors such as transport stress and breed and age correlations have been identified, biologic factors such as genetic predispositions of individual animals, and parasite-specific factors such as strain differences in virulence, remain largely undetermined. This consensus statement …

Awareness Of Rabies And Response To Dog Bites In A Bangladesh Community, Sumon Ghosh, Sukanta Chowdhury, Najmul Haider, Rajub K. Bhowmik, Md. S. Rana, Aung S. Prue Marma, Muhammad B. Hossain, Nitish C. Debnath, Be-Nazir Ahmed

Publications and Research

Community awareness regarding rabies and treatment seeking behaviours are critical both for the prevention and control of the disease in human and animals. We conducted a study to explore people’s awareness about rabies, their attitudes towards dogs and practices associated with treating dog bites in Satkhira Sadar, a southwestern sub-district of Bangladesh. Of the total 3200 households (HHs) surveyed, the majority of the respondents have heard about rabies (73%) and there was a high level of awareness that dog bite is the main cause of rabies (86%), and that rabies can be prevented by vaccination (85%). However, 59% of the …

Comparison Of Protein Phosphatase Inhibition Assay With Lc-Ms/Ms For Diagnosis Of Microcystin Toxicosis In Veterinary Cases, Caroline E. Moore, Jeanette Juan, Yanping Lin, Cynthia L. Gaskill, Birgit Puschner

Veterinary Diagnostic Laboratory Faculty Publications

Microcystins are acute hepatotoxins of increasing global concern in drinking and recreational waters and are a major health risk to humans and animals. Produced by cyanobacteria, microcystins inhibit serine/threonine protein phosphatase 1 (PP1). A cost-effective PP1 assay using p-nitrophenyl phosphate was developed to quickly assess water and rumen content samples. Significant inhibition was determined via a linear model, which compared increasing volumes of sample to the log-transformed ratio of the exposed rate over the control rate of PP1 activity. To test the usefulness of this model in diagnostic case investigations, samples from two veterinary cases were tested. In August …

Circulating Amino Acids In Blood Plasma During The Peripartal Period In Dairy Cows With Different Liver Functionality Index, Z. Zhou, J. J. Loor, F. Piccioli-Cappelli, F. Librandi, G. E. Lobley, E. Trevisi

Physiology Collection

The liver functionality index (LFI) measures the changes of albumin, cholesterol, and bilirubin concentrations between 3 and 28 d postpartum. This composite index, based on variables with direct relevance to liver-specific plasma protein synthesis (albumin), hepatic/intestinal lipoprotein synthesis (cholesterol), and clearance of breakdown products of heme catabolism (bilirubin), provides a tool for evaluating manifestations of hepatic disease. Both energy and protein metabolism are likely to be affected by various physiological challenges in this period but have not been tested systematically. The present study was conducted to profile AA in cows with high or low LFI during the peripartal period …

Mechanical Conflict System: A Novel Operant Method For The Assessment Of Nociceptive Behavior, Steven E. Harte, Jessica B. Meyers, Renee R. Donahue, Bradley K. Taylor, Thomas J. Morrow

Physiology Faculty Publications

A new operant test for preclinical pain research, termed the Mechanical Conflict System (MCS), is presented. Rats were given a choice either to remain in a brightly lit compartment or to escape to a dark compartment by crossing an array of height-adjustable nociceptive probes. Latency to escape the light compartment was evaluated with varying probe heights (0, .5, 1, 2, 3, and 4 mm above compartment floor) in rats with neuropathic pain induced by constriction nerve injury (CCI) and in naive control rats. Escape responses in CCI rats were assessed following intraperitoneal administration of pregabalin (10 and 30 mg/kg), morphine …

Evaluation Of Calving Indicators Measured By Automated Monitoring Devices To Predict The Onset Of Calving In Holstein Dairy Cows, V. Ouellet, E. Vasseur, W. Heuwieser, O. Burfeind, X. Maldague, É. Charbonneau

Physiology Collection

Dystocias are common in dairy cows and often adversely affect production, reproduction, animal welfare, labor, and economics within the dairy industry. An automated device that accurately predicts the onset of calving could potentially minimize the effect of dystocias by enabling producers to intervene early. Although many well-documented indicators can detect the imminence of calving, research is limited on their effectiveness to predict calving when measured by automated devices. The objective of this experiment was to determine if a decrease in vaginal temperature (VT), rumination (RT), and lying time (LT), or an increase in lying bouts (LB), as measured by …

The Pseudorabies Virus Protein, Pul56, Enhances Virus Dissemination And Virulence But Is Dispensable For Axonal Transport, Gina R. Daniel, Patricia J. Sollars, Gary E. Pickard, Gregory A. Smith

School of Veterinary and Biomedical Sciences: Faculty Publications

Neurotropic herpesviruses exit the peripheral nervous system and return to exposed body surfaces following reactivation from latency. The pUS9 protein is a critical viral effector of the anterograde axonal transport that underlies this process. We recently reported that while pUS9 increases the frequency of sorting of newly assembled pseudorabies virus particles to axons from the neural soma during egress, subsequent axonal transport of individual virus particles occurs with wild-type kinetics in the absence of the protein. Here, we examine the role of a related pseudorabies virus protein, pUL56, during neuronal infection. The findings indicate that pUL56 is a virulence factor …

Toxoplasma gondii is among the most prevalent parasites worldwide, infecting many wild and domestic animals and causing zoonotic infections in humans. T. gondii differs substantially in its broad distribution from closely related parasites that typically have narrow, specialized host ranges. To elucidate the genetic basis for these differences, we compared the genomes of 62 globally distributed T. gondii isolates to several closely related coccidian parasites. Our findings reveal that tandem amplification and diversification of secretory pathogenesis determinants is the primary feature that distinguishes the closely related genomes of these biologically diverse parasites. We further show that the unusual population structure …

Autoimmunity In Picornavirus Infections, Chandirasegara Massilamany, Andreas Koenig, Jay Reddy, Sally Huber, Iwona Buskiewicz

School of Veterinary and Biomedical Sciences: Faculty Publications

Enteroviruses are small, non-enveloped, positive-sense singlestrand RNA viruses, and are ubiquitously found throughout the world. These viruses usually cause asymptomatic or mild febrile illnesses, but have a propensity to induce severe diseases including type 1 diabetes and pancreatitis, paralysis and neuroinflammatory disease, myocarditis, or hepatitis. This pathogenicity may result from induction of autoimmunity to organ-specific antigens. While enterovirus-triggered autoimmunity can arise from multiple mechanisms including antigenic mimicry and release of sequestered antigens, the recent demonstration of T cells expressing dual T cell receptors arising as a natural consequence of Theiler’s virus infection is the first demonstration of this autoimmune mechanism.

From Crystal Structure Of Α-Conotoxin Gic In Complex With Ac-Achbp To Molecular Determinants Of Its High Selectivity For Α3Β2 Nachr, Bo Lin, Manyu Xu, Xiaopeng Zhu, Yong Wu, Xi Liu, Dongting Zhangsun, Yuanyan Hu, Shi-Hua Xiang, Igor E. Kasheverov, Victor I. Tsetlin, Xianquan Wang, Sulan Luo

School of Veterinary and Biomedical Sciences: Faculty Publications

Acetylcholine binding proteins (AChBPs) are unique spatial homologs of the ligand-binding domains of nicotinic acetylcholine receptors (nAChRs), and they reproduce some pharmacological properties of nAChRs. X-ray crystal structures of AСhBP in complex with α-conotoxins provide important insights into the interactions of α-conotoxins with distinct nAChR subtypes. Although considerable efforts have been made to understand why α-conotoxin GIC is strongly selective for α3β2 nAChR, this question has not yet been solved. Here we present the structure of α-conotoxin GIC in complex with Aplysia californica AChBP (Ac-AChBP) at a resolution of 2.1 Å. Based on this co-crystal structure complemented with molecular docking …

Expression And Distribution Of Thiol-Regulating Enzyme Glutaredoxin 2 (Grx2) In Porcine Ocular Tissues, Bijaya Upadhyaya, Xiaoli Tian, Hongli Wu, Marjorie F. Lou

School of Veterinary and Biomedical Sciences: Faculty Publications

Glutaredoxin2 (Grx2) is a mitochondrial isozyme of the cytosolic glutaredoxin1 (thioltransferase or TTase). Both belong to the large oxidoreductase family and play an important role in maintaining thiol/disulfide redox homeostasis in the cells. Grx2 is recently found in the lens where its activities of disulfide reductase and peroxidase, similar to TTase, can protect the lens against oxidative stress. Since other eye tissues are also highly sensitive to oxidative stress, and TTase’s distribution in the eye is known, we focused on this study by investigating the Grx2 distribution in the ocular tissues in comparison to the lens. Fresh porcine eyes were …

A Synthetic Porcine Reproductive And Respiratory Syndrome Unprecedented Levels Of Heterologous Protection, Hiep Vu, Fangrui Ma, William W. Laegreid, Asit K. Pattnaik, David Steffen, Alan R. Doster, Fernando A. Osorio

School of Veterinary and Biomedical Sciences: Faculty Publications

Current vaccines do not provide sufficient levels of protection against divergent porcine reproductive and respiratory syndrome virus (PRRSV) strains circulating in the field, mainly due to the substantial variation of the viral genome. We describe here a novel approach to generate a PRRSV vaccine candidate that could confer unprecedented levels of heterologous protection against divergent PRRSV isolates. Using a set of 59 non-redundant, full genome sequences of type-2 PRRSV, a consensus genome (designated as PRRSV-CON) was these 59 PRRSV full genome sequences, followed by selecting the most common nucleotide found at each position of the alignment. Next, the synthetic PRRSV-CON …

Overview Of Rhabdo- And Filoviruses, Asit K. Pattnaik, Michael A. Whitt

School of Veterinary and Biomedical Sciences: Faculty Publications

Enveloped viruses with a negative-sense, single-stranded monopartite RNA genome have been classified into the order Mononegavirales. Five families of viruses that constitute the order are: Rhabdoviridae, Filoviridae, Paramyxoviridae, Bornaviridae and Nyamiviridae. Members of these families possess a helical nucleocapsid core containing the viral genome and a host-derived lipid envelope containing viral proteins. This introductory chapter provides a brief overview of the Rhabdoviridae and the Filoviridae, the two families of viruses that are the subject of this book. Many members of these two families are highly significant human and animal pathogens. The rationale and goal of the book is to …

Whole Genomic Sequence Analysis Of Bacillus Infantis: Defining The Genetic Blueprint Of Strain Nrrl B-14911, An Emerging Cardiopathogenic Microbe, Chandirasegara Massilamany, Akram Mohammed, John Dustin Loy, Tanya Purvis, Bharathi Krishnan, Rakesh H. Basavalingappa, Christy M. Kelley, Chittibabu Guda, Raúl G. Barletta, Etsuko N. Moriyama, Timothy P.L. Smith, Jay Reddy

School of Veterinary and Biomedical Sciences: Faculty Publications

Background: We recently reported the identification of Bacillus sp. NRRL B-14911 that induces heart autoimmunity by generating cardiac-reactive T cells through molecular mimicry. This marine bacterium was originally isolated from the Gulf of Mexico, but no associations with human diseases were reported. Therefore, to characterize its biological and medical significance, we sought to determine and analyze the complete genome sequence of Bacillus sp. NRRL B-14911.

Results: Based on the phylogenetic analysis of 16S ribosomal RNA (rRNA) genes, sequence analysis of the 16S-23S rDNA intergenic transcribed spacers, phenotypic microarray, and matrix-assisted laser desorption ionization time-offlight mass spectrometry, we propose that this …

New Tools To Convert Bacterial Artificial Chromosomes To A Self-Excising Design And Their Application To A Herpes Simplex Virus Type 1 Infectious Clone, Alexsia L. Richards, Patricia J. Sollars, Gregory A. Smith

School of Veterinary and Biomedical Sciences: Faculty Publications

Background: Infectious clones are fundamental tools for the study of many viruses, allowing for efficient mutagenesis and reproducible production of genetically-defined strains. For the large dsDNA genomes of the herpesviridae, bacterial artificial chromosomes have become the cloning vector of choice due to their capacity to house full-length herpesvirus genomes as single contiguous inserts. Furthermore, while maintained as plasmids in Escherichia coli, the clones can be mutated using robust prokaryotic recombination systems. An important consideration in the design of these clones is the means by which the vector backbone is removed from the virus genome upon delivery into mammalian cells. …

Resolving Bovine Viral Diarrhea Virus Subtypes From Persistently Infected U.S. Beef Calves With Complete Genome Sequence, Aspen M. Workman, Michael P. Heaton, Gregory P. Harhay, Timothy P.L. Smith, Dale M. Grotelueschen, David Sjeklocha, Bruce Brodersen, Jessica L. Petersen, Carol G. Chitko-Mckown

School of Veterinary and Biomedical Sciences: Faculty Publications

Bovine viral diarrhea virus (BVDV) is classified into 2 genotypes, BVDV-1 and BVDV-2, each of which contains distinct subtypes with genetic and antigenic variation. To effectively control BVDV by vaccination, it is important to know which subtypes of the virus are circulating and how their prevalence is changing over time. Accordingly, the purpose of our study was to estimate the current prevalence and diversity of BVDV subtypes from persistently infected (PI) beef calves in the central United States. Phylogenetic analysis of the 5′-UTR (5′ untranslated region) for 119 virus strains revealed that a majority (82%) belonged to genotype 1b, and …

Maporal Hantavirus Causes Mild Pathology In Deer Mice (Peromyscus Maniculatus), Amanda Mcguire, Kaitlyn Miedema, Joseph R. Fauver, Amber Rico, Tawfik Aboellail, Sandra L. Quackenbush, Ann Hawkinson, Tony Schountz

School of Veterinary and Biomedical Sciences: Faculty Publications

Rodent-borne hantaviruses can cause two human diseases with many pathological similarities: hantavirus cardiopulmonary syndrome (HCPS) in the western hemisphere and hemorrhagic fever with renal syndrome in the eastern hemisphere. Each virus is hosted by specific reservoir species without conspicuous disease. HCPS-causing hantaviruses require animal biosafety level-4 (ABSL-4) containment, which substantially limits experimental research of interactions between the viruses and their reservoir hosts. Maporal virus (MAPV) is a South American hantavirus not known to cause disease in humans, thus it can be manipulated under ABSL-3 conditions. The aim of this study was to develop an ABSL-3 hantavirus infection model using the …

Prevalence And Level Of Enterohemorrhagic Escherichia Coli In Culled Dairy Cows At Harvest, Zachary R. Stromberg, Gentry L. Lewis, Sharif S. Aly, Terry W. Lehenbauer, Joseph M. Bosilevac, Natalia Cernicchiaro, Rodney A. Moxley

School of Veterinary and Biomedical Sciences: Faculty Publications

The primary objective of this study was to determine the prevalence and level of enterohemorrhagic Escherichia coli (EHEC) O26, O45, O103, O111, O121, and O145 (collectively EHEC-6) plus EHEC O157 in fecal, hide, and preintervention carcass surface samples from culled dairy cows. Matched samples (n=300) were collected from 100 cows at harvest and tested by a culture-based method and two molecular methods: NeoSEEK STEC (NS) and Atlas STEC EG2 Combo. Both the culture and NS methods can be used to discriminate among the seven EHEC types (EHEC-7), from which the cumulative prevalence was inferred, whereas the Atlas method can discriminate …

Mosquito Host Choices On Livestock Amplifiers Of Rift Valley Fever Virus In Kenya, David P. Tchouassi, Robinson O. Okiro, Rosemary Sang, Lee W. Cohnstaedt, D. Scott Mcvey, Baldwyn Torto

School of Veterinary and Biomedical Sciences: Faculty Publications

Background: Animal hosts may vary in their attraction and acceptability as components of the host location process for assessing preference, and biting rates of vectors and risk of exposure to pathogens. However, these parameters remain poorly understood for mosquito vectors of the Rift Valley fever (RVF), an arboviral disease, and for a community of mosquitoes.

Methods: Using three known livestock amplifiers of RVF virus including sheep, goat and cattle as bait in enclosure traps, we investigated the host-feeding patterns for a community of mosquitoes in Naivasha, an endemic area of Rift Valley fever (RVF), in a longitudinal study for six …

Cobalt Use And Regulation In Horseracing: A Review, K. Brewer, G. Maylin, C. K. Fenger, Thomas Tobin

Veterinary Science Faculty Publications

Cobalt, atomic weight 58.9, is a metallic element and environmental substance found in the animal in microgram quantities, predominantly as vitamin B12, but is also a component of at least one mammalian enzyme unassociated with B12. Cobalt is a required trace mineral and has long been administered as a dietary supplement to humans and animals. Cobalt deficiency outside of its requirement in vitamin B12 has not been reported in humans. The administration of cobalt salts was once standard treatment for anaemia in humans, owing to its ability to stimulate red blood cell synthesis. Elemental cobalt acts by stabilising hypoxia inducible …

Exploring Attitudes Toward Euthanasia Among Shelter Workers And Volunteers In Japan And The U.S., Maho Cavalier

HSU STUDENT THESES AND CAPSTONE PROJECTS

Conflicts between foreign and Japanese volunteers concerning decisions to euthanize animals that are in terminal condition were noted during anecdotal observation by this author at a Japanese animal rescue shelter. Thus, this research was undertaken to explore attitudes of shelter staff in Japan. As a point of comparison, U. S. shelter workers were also interviewed. Twenty current or former shelter workers (16 participants from Japan and 4 participants from the U.S.), ranging in age from 20 to 65, were interviewed. Face-to-face interviews were conducted with the Japanese participants; e-mail and/or Skype were used to conduct the interviews with the participants …

Body Condition Score And Plane Of Nutrition Prepartum Affect Adipose Tissue Transcriptome Regulators Of Metabolism And Inflammation In Grazing Dairy Cows During The Transition Period, M. Vailati-Riboni, M. Kanwal, O. Bulgari, S. Meier, N. V. Priest, C. R. Burke, J. K. Kay, S. Mcdougall, M. D. Mitchell, C. G. Walker, M. Crookenden, A. Heiser, J. R. Roche, J. J. Loor

Physiology Collection

Recent studies demonstrating a higher incidence of metabolic disorders after calving have challenged the management practice of increasing dietary energy density during the last ~3 wk prepartum. Despite our knowledge at the whole-animal level, the tissue-level mechanisms that are altered in response to feeding management prepartum remain unclear. Our hypothesis was that prepartum body condition score (BCS), in combination with feeding management, plays a central role in the peripartum changes associated with energy balance and inflammatory state. Twenty-eight mid-lactation grazing dairy cows of mixed age and breed were randomly allocated to 1 of 4 treatment groups in a 2 × …

Dry Period Plane Of Energy: Effects On Glucose Tolerance In Transition Dairy Cows, S. Mann, F. A. Leal Yepes, M. Duplessis, J. J. Wakshlag, T. R. Overton, B. P. Cummings, D. V. Nydam

Physiology Collection

Overfeeding energy in the dry period can affect glucose metabolism and the energy balance of transition dairy cows with potential detrimental effects on the ability to successfully adapt to early lactation. The objectives of this study were to investigate the effect of different dry cow feeding strategies on glucose tolerance and on resting concentrations of blood glucose, glucagon, insulin, nonesterified fatty acids (NEFA), and β-hydroxybutyrate (BHB) in the peripartum period. Cows entering second or greater lactation were enrolled at dry-off (57 d before expected parturition) into 1 of 3 treatment groups following a randomized block design: cows …

Localization Of Cd8 T Cell Epitope Within Cardiac Myosin Heavy Chain-Α334-352 That Induces Autoimmune Myocarditis In A/J Mice, Chandirasegara Massilamany, Arunakumar Gangaplara, Rakesh H. Basavalingappa, Rajkumar A. Rajasekaran, Vahid Khalilzad-Sharghi, Zhongji Han, Shadi F. Othman, David Steffen, Jay Reddy

School of Veterinary and Biomedical Sciences: Faculty Publications

Background—Cardiac myosin heavy chain-α (Myhc), an intracellular protein expressed in the cardiomyocytes, has been identified as a major autoantigen in cardiac autoimmunity. In our studies with Myhc_334-352-induced experimental autoimmune myocarditis in A/J mice (H-2a), we discovered that Myhc_334-352, supposedly a CD4 T cell epitope, also induced antigen-specific CD8 T cells that transfer disease to naïve animals.

Methods and Results—In our efforts to identify the CD8 T cell determinants, we localized Myhc_338-348 within the full length-Myhc_334-352, leading to four key findings. (1) By acting as a dual epitope, Myhc_338-348 induces both …

Visualizing Herpesvirus Procapsids In Living Cells, Oana Maier, Patricia J. Sollars, Gary E. Pickard, Gregory A. Smith

School of Veterinary and Biomedical Sciences: Faculty Publications

A complete understanding of herpesvirus morphogenesis requires studies of capsid assembly dynamics in living cells. Although fluorescent tags fused to the VP26 and pUL25 capsid proteins are available, neither of these components is present on the initial capsid assembly, the procapsid. To make procapsids accessible to live-cell imaging, we made a series of recombinant pseudorabies viruses that encoded green fluorescent protein (GFP) fused in frame to the internal capsid scaffold and maturation protease. One recombinant, a GFP-VP24 fusion, maintained wild-type propagation kinetics in vitro and approximated wild-type virulence in vivo. The fusion also proved to be well tolerated in …

Guidelines For The Use And Interpretation Of Assays For Monitoring Autophagy (3rd Edition), Daniel J. Klionsky, Rodrigo Franco, More Than 2,000 Co-Authors

School of Veterinary and Biomedical Sciences: Faculty Publications

In 2008 we published the first set of guidelines for standardizing research in autophagy. Since then, research on this topic has continued to accelerate, and many new scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Accordingly, it is important to update these guidelines for monitoring autophagy in different organisms. Various reviews have described the range of assays that have been used for this purpose. Nevertheless, there continues to be confusion regarding acceptable methods to measure autophagy, especially in multicellular eukaryotes.

For example, a key point that needs to be emphasized is that …

Genome-Wide Search For Host Association Factors During Ovine Progressive Pneumonia Virus Infection, Jesse Thompson, Fangrui Ma, Meghan Quinn, Shi-Hua Xiang

School of Veterinary and Biomedical Sciences: Faculty Publications

Ovine progressive pneumonia virus (OPPV) is an important virus that causes serious diseases in sheep and goats with a prevalence of 36% in the USA. Although OPPV was discovered more than half of a century ago, little is known about the infection and pathogenesis of this virus. In this report, we used RNA-seq technology to conduct a genome-wide probe for cellular factors that are associated with OPPV infection. A total of approximately 22,000 goat host genes were detected of which 657 were found to have been significantly up-regulated and 889 down-regulated at 12 hours post-infection. In addition to previously known …
