Veterinary Ethics And Production Diseases, Bernard E. Rollin Aug 2009

Veterinary Ethics And Production Diseases, Bernard E. Rollin

Professional Veterinary Ethics Collection

An animal's welfare should be governed by five freedoms, namely, freedom from hunger and thirst, freedom from discomfort, freedom from pain, injury or disease, freedom to express normal behavior and freedom from fear and distress. If the essence of veterinary medicine is to act like a physician for animals then the profession must be vocal in opposition to production diseases, which can be prevented by changing the system of production.

A New Approach For Managing Bovine Tuberculosis: Veterinary Services’ Proposed Action Plan Jul 2009

A New Approach For Managing Bovine Tuberculosis: Veterinary Services’ Proposed Action Plan

Michigan Bovine Tuberculosis Bibliography and Database

Bovine tuberculosis (TB) is a serious disease with animal health, public health, and international trade consequences. The cooperative Federal-State-industry effort to eradicate bovine TB from cattle in the United States has made significant progress since the program’s inception in 1917. However, the goal of eradication remains elusive.

This proposed action plan presents Veterinary Services’ (VS’) current thinking about changes we are considering for the TB program to address our current challenges.

This action plan will:
1. Reduce the introduction of TB into the U.S. national herd from imported animals and wildlife by:
o Applying additional requirements to cattle imports from …


Gp3 Is A Structural Component Of The Prrsv Type Ii (Us) Virion, M. De Lima, I. H. Ansari, P. B. Das, B. J. Ku, F. J. Martinez-Lobo, Fernando A. Osorio Jul 2009

Gp3 Is A Structural Component Of The Prrsv Type Ii (Us) Virion, M. De Lima, I. H. Ansari, P. B. Das, B. J. Ku, F. J. Martinez-Lobo, Fernando A. Osorio

School of Veterinary and Biomedical Sciences: Faculty Publications

Abstract Glycoprotein 3 (GP3) is a highly glycosylated PRRSV envelope protein which has been reported as being present in the virions of PRRSV type I, while missing in the type II PRRSV (US) virions. We herein present evidence that GP3 is indeed incorporated in the virus particles of a North American strain of PRRSV (FL12), at a density that is consistent with the minor structural role assigned to GP3 in members of the Arterivirus genus. Two 15aa peptides corresponding to two different immunodominant linear epitopes of GP3 derived from the North American strain of PRRSV (FL12) were used as antigen …

A herd was selected based on history and serological data. Three-week-old pigs (n = 200) were equally divided into two groups. At 4 weeks old, the pigs (n = 100) were injected intramuscularly with 2 ml of Suvaxyn PCV2® vaccine and the non-vaccinated pigs were injected with 2 ml of normal saline. Sera were collected from 20 pigs per group …


Single-Amino-Acid Alterations In A Highly Conserved Central Region Of Vesicular Stomatitis Virus N Protein Differentially Affect The Viral Nucleocapsid Template Functions, Debasis Nayak, Debasis Panda, Subash C. Das, Ming Lou, Asit K. Pattnaik Jun 2009

Single-Amino-Acid Alterations In A Highly Conserved Central Region Of Vesicular Stomatitis Virus N Protein Differentially Affect The Viral Nucleocapsid Template Functions, Debasis Nayak, Debasis Panda, Subash C. Das, Ming Lou, Asit K. Pattnaik

School of Veterinary and Biomedical Sciences: Faculty Publications

The nucleocapsid protein (N) of vesicular stomatitis virus and other rhabdoviruses plays a central role in the assembly and template functions of the viral N-RNA complex. The crystal structure of the viral N-RNA complex suggests that the central region of the N protein interacts with the viral RNA. Sequence alignment of rhabdovirus N proteins revealed several highly conserved regions, one of which spanned residues 282 to 291 (GLSSKSPYSS) in the central region of the molecule. Alanine-scanning mutagenesis of this region suggested that replacement of the tyrosine residue at position 289 (Y289) with alanine resulted in an N-RNA template that is …

The Use Of Earthworms In Lab-Scale Constructed Wetlands To Treat Swine Wastewater, Nathasith Chiarawatchai, Chackrit Nuengjamnong

The Thai Journal of Veterinary Medicine

This study investigated the effect of adding local earthworms (Pheretima peguana) into several configurations of the lab-scale constructed wetlands reactors receiving swine wastewater in terms of their treatment performances, namely a decrease in organic matter, TKN, and solids. The results indicated that the performance of the lab-scale units with earthworms was better in the presence of earthworms. In terms of optimal configuration, the vertical subsurface-flow constructed wetlands with earthworms, sequentially followed by horizontal subsurface-flow constructed wetlands had generally the best treatment performance. This configuration decreased BOD, COD, TVSS, and SS by more than 90%, as well as TKN and TS …

Canine Amniotic Membrane Transplantation For Ocular Surface Reconstruction Of Created Deep Corneal Ulcers In Dogs, Simon Vongsakul, Pranee Tuntivanich, Sudson Sirivaidyapong, Marissak Kalpravidh

The Thai Journal of Veterinary Medicine

Canine amniotic membrane (AM) transplantation in conjunction with a third eyelid flap was used to promote healing of created deep corneal ulcers in 6 normal mongrel dogs. The healing was compared with the healing of created ulcers in the other eye of the same dog that were treated only with the third eyelid flap. A minimum of 60 days interval was allowed between the two treatment procedures in the 2 eyes of each dog. To simulate corneal ulcers found clinically, the surgical treatment was performed three days after the ulcer had been created. Cultures from preoperative conjunctival swabs revealed Staphylococcus …

A Replicon Trans-Packaging System Reveals The Requirement Of Nonstructural Proteins For The Assembly Of Bovine Viral Diarrhea Virus (Bvdv) Virion, Delin Liang, Limei Chen, Israrul H. Ansari, Laura H. V. G. Gil, Christina L. Topliff, Clayton L. Kelling, Ruben O. Donis May 2009

A Replicon Trans-Packaging System Reveals The Requirement Of Nonstructural Proteins For The Assembly Of Bovine Viral Diarrhea Virus (Bvdv) Virion, Delin Liang, Limei Chen, Israrul H. Ansari, Laura H. V. G. Gil, Christina L. Topliff, Clayton L. Kelling, Ruben O. Donis

School of Veterinary and Biomedical Sciences: Faculty Publications

A selective trans-packaging system was developed to produce and isolate bovine viral diarrhea virus (BVDV) pseudo-particles with complementing reporter replicons and their packaging proteins expressed in trans with recombinant vaccinia virus. The encapsidation of replicon rNS3-5B was dependent not only on the in trans expression of structural proteins C, Erns, E1 and E2, but also the nonstructural proteins, p7 and contiguous precursor NS2-3-4A. Nonstructural p7, NS4B, NS5A or NS5B could be expressed in cis and in trans with precursor NS2-3-4A without significantly affecting virion assembly efficiency. NS2-3-4A was identified as an in trans functional precursor in virion assembly. BVDV …

Chronic Wasting Disease Prions In Elk Antler Velvet, Rachel C. Angers, Tanya S. Seward, Dana Napier, Michael Green, Edward Hoover, Terry Spraker, Katherine O'Rourke, Aru Balachandran, Glenn C. Telling

Zoonotics and Wildlife Disease: Publications

Chronic wasting disease (CWD) is a contagious, fatal prion disease of deer and elk that continues to emerge in new locations. To explore the means by which prions are transmitted with high efficiency among cervids, we examined prion infectivity in the apical skin layer covering the growing antler (antler velvet) by using CWD-susceptible transgenic mice and protein misfolding cyclic amplification. Our finding of prions in antler velvet of CWD-affected elk suggests that this tissue may play a role in disease transmission among cervids. Humans who consume antler velvet as a nutritional supplement are at risk for exposure to prions. The …

Contact Networks In A Wildlife-Livestock Host Community: Identifying High-Risk Individuals In The Transmission Of Bovine Tb Among Badgers And Cattle, Monika Böhm, Michael R. Hutchings, Piran C. L. White Apr 2009

Contact Networks In A Wildlife-Livestock Host Community: Identifying High-Risk Individuals In The Transmission Of Bovine Tb Among Badgers And Cattle, Monika Böhm, Michael R. Hutchings, Piran C. L. White

Michigan Bovine Tuberculosis Bibliography and Database

Background: The management of many pathogens, which are of concern to humans and their livestock, is complicated by the pathogens’ ability to cross-infect multiple host species, including wildlife. This has major implications for the management of such diseases, since the dynamics of infection are dependent on the rates of both intra- and inter-specific transmission. However, the difficulty of studying transmission networks in free-living populations means that the relative opportunities for intra- versus inter-specific disease transmission have not previously been demonstrated empirically within any wildlife-livestock disease system. Methodology/Principal Findings: Using recently-developed proximity data loggers, we quantify both intra-and interspecific contacts in …


Healthy Paws Doggie Day Camp, Alexandra Salazar Mar 2009

Healthy Paws Doggie Day Camp, Alexandra Salazar

Undergraduate Research Conference

“Healthy Paws Doggie Day Camp” is an event that will help owners and dogs incorporate physical activity into their daily lives. General knowledge of exercise concerning dogs is considerably lacking, obviously observed as they become more obese over time (Fennell, 2005). Between 40-50 percent of our dogs are overweight (Fennell, 2005). It is not only humans who have trouble controlling their body weight, while metabolism begins to slow down with age, canines are also affected. (Borzendowski, 2007).Walking a dog could help a large proportion of the U.S. population [dog owners] increase their physical activity as well as that of their …
