Prevention And Control Of Respiratory Diseases Excluding Mycoplasma Hyopneumoniae, Stanley Done, David Burch

The Thai Journal of Veterinary Medicine

Significant changes in respiratory disease have occurred over the last 20 years. There are two primary reasons for this. In the first instance, there has been the occurrence of two major worldwide plagues-PRRS and PCV2-associated diseases. The second reason has been the considerable advances in vaccination, which have become available for some of the respiratory diseases, in particular Mycoplasma hyopneumoniae. Vaccines have also become available for porcine reproductive and respiratory syndrome virus (PRRS), influenza viruses (outside UK) and probably in the near future against porcine circovirus type 2 (PCV2).

Results revealed that the positive reactors detected by the SPA test, ELISA …

Effects Of A Beta Adrenergic Antagonist Combined With Vasodilators On Cardiac Arrhythmia In Ischemic-Induced Rat Hearts, Promporn Raksaseri, Wuthichai Klomkleaw, Suwanakiet Sawangkoon

The Thai Journal of Veterinary Medicine

Sixty male Spraque-Dawley rats were used in this study. The hearts were isolated and placed on a constant-pressure Langendorff apparatus, and perfused with only Krebs-Henseleit buffer (control), atenolol, atenolol plus prazosin, and atenolol plus salbutamol. After that the left anterior descending artery was occluded for 8 minutes and reperfused for 30 minutes to induce cardiac arrhythmias. The left ventricular pressure and coronary flow rate were monitored, and ECGs were recorded to evaluate cardiac arrhythmias. The administration of atenolol (β1-adrenergic antagonist) combined with prazosin (α1-adrenergic antagonist) prolonged RR intervals whereas that of atenolol combined with salbutamol (β2-adrenergic antagonist) did not prolong …

Our conclusions support the more generally accepted view that the large brain of cetaceans evolved to support complex cognitive abilities.

A Comparison Of Pyronin Y-Methyl Green Stain And Methylene Blue Stain For Somatic Cell Count In Sheep Milk, Emily Mirek, Stacey O’Donnell

Senior Honors Projects

Somatic cell count is a key method used to evaluate the quality of milk in today’s growing dairy sheep industry. Somatic cells are body cells, primarily the white blood cells, found in a milk sample. If an infection such as mastitis is present, the number of somatic cells in the milk increases (Gonzalo, et al. 1992). Producers routinely perform somatic cell counts on cow and goat milk. For dairy cattle in the United States, the somatic cell count can not exceed 750,000 cells per milliliter, for commercial milk. For dairy goats the accepted limit is 1,000,000 cells per mL of …

Spatial And Temporal Patterns Of Enzootic Raccoon Rabies Adjusted For Multiple Covariates, Sergio Recuenco, Millicent Eidson, Martin Kulldorff, Glen Johnson, Bryan Cherry

Zoonotics and Wildlife Disease: Publications

Background: With the objective of identifying spatial and temporal patterns of enzootic raccoon variant rabies, a spatial scan statistic was utilized to search for significant terrestrial rabies clusters by year in New York State in 1997–2003. Cluster analyses were unadjusted for other factors, adjusted for covariates, and adjusted for covariates and large scale geographic variation (LSGV). Adjustments were intended to identify the unusual aggregations of cases given the expected distribution based on the observed locations.

Results: Statistically significant clusters were identified particularly in the Albany, Finger Lakes, and South Hudson areas. The clusters were generally persistent in the Albany area, …

Potential Cost Savings With Terrestrial Rabies Control, Sergio Recuenco, Bryan Cherry, Millicent Eidson

Zoonotics and Wildlife Disease: Publications

Background: The cost-benefit of raccoon rabies control strategies such as oral rabies vaccination (ORV) are under evaluation. As an initial quantification of the potential cost savings for a control program, the collection of selected rabies cost data was pilot tested for five counties in New York State (NYS) in a three-year period.

Methods: Rabies costs reported to NYS from the study counties were computerized and linked to a human rabies exposure database. Consolidated costs by county and year were averaged and compared.

Results: Reported rabies-associated costs for all rabies variants totalled $2.1 million, for human rabies postexposure prophylaxes (PEP) (90.9%), …

The Infected Cell Protein 0 Encoded By Bovine Herpesvirus 1 (Bicp0) Induces Degradation Of Interferon Response Factor 3 And, Consequently, Inhibits Beta Interferon Promoter Activity, Kazima Saira, You Zhou, Clinton J. Jones

School of Veterinary and Biomedical Sciences: Faculty Publications

The ICP0 protein (bICP0) encoded by bovine herpesvirus 1 is the major viral regulatory protein because it stimulates all viral promoters and, consequently, productive infection. Like other ICP0 analogues encoded by Alphaherpesvirinae subfamily members, bICP0 contains a zinc RING finger near its amino terminus that is necessary for activating transcription, regulating subcellular localization, and inhibiting interferon-dependent transcription. In this study, we discovered that sequences near the C terminus, and the zinc RING finger, are necessary for inhibiting the human beta interferon (IFN- β) promoter. In contrast to herpes simplex virus type 1-encoded ICP0, bICP0 reduces interferon response factor 3 (IRF3), …

Hence, training programs must address all discipline areas to achieve the desired outcome of robust service delivery to meet all stakeholder group needs. The current and future needs for AAH training have been identified across many sectors through survey work and direct interviews with key stakeholders. There is a shortfall in both total capacity and more prominently, in the availability of high skill …

The Molecular Identification Of Mycoplasma Haemofelis And Mycoplasma Haemominutum In Cats Suffering From Haemoplasmosis In Thailand, Sudchit Chungpivat, Meena Sarikaputi, Supparin Jirasukprasert, Siriluk Jenchangkol, Nareerat Viseshakul

The Thai Journal of Veterinary Medicine

Haemotrophic Mycoplasma is the obligatory bacteria formerly classified to the genus Haemobartonella. This blood mycoplasma is responsible for the cause of a cat disease, haemoplasmosis or feline infectious anemia (FIA). The housed cats evidenced by cachexia, high fever and a certain degree of anemic condition have been reported with FIA worldwide. However, this disease is only a presumptive case in Thailand where the disease is presumably endemic. We examined two cats suffering from FIA tested with the standard microscopic examination. With the destruction of erythrocytes, one cat had only a mild clinical condition while the other was severe. The parasitized …

Body Weight Formulation In Asian Elephant, Sumolya Kanchanapangka, Sunisa Supawong, Klinsukon Koedlab, Jirasak Kaewpannarai, Puttipong Khawnual, Padet Tummaruk, Kriengyot Sajjarengpong

The Thai Journal of Veterinary Medicine

Accurate estimation of body weight is useful for feeding program evaluation, assessing nutritional status and general health, and for accurate dose calculation in medical treatment. However, it is impractical to weigh elephants due to their enormous size and tremendous weight, and also due to the lack of a suitable weighing machine. The objective of the present study was to correlate various body measurements and actual body weight of the elephant in order to formulate a regression model to approximate the body weight of the elephant from body measurements. Seventy-eight Asian elephants (Elephas maximus indicus) comprising 18 males and 60 females, …

Strategies For The Control Of Respiratory Disease, Stanley Done

The Thai Journal of Veterinary Medicine

This is a paper about common sense and respiratory disease using information that has been known for some time i.e. historical, and which is not accessed when a literary search is supplied by a computer. Respiratory disease in pigs has its most serious effects in the finishing stages, when the sequelae to progressive atrophic rhinitis, enzootic pneumonia and Actinobacillosis are most severe. Nowadays this relatively simple position is even more complicated by the worldwide occurrence of porcine reproductive and respiratory syndrome (PRRS) and porcine circovirus type 2 (PCV-2)-associated diseases principally PMWS where no vaccination is practised. Up to 80% of …

Congenital Oesophageal Stenosis In A Puppy, Churee Pramatwinai

The Thai Journal of Veterinary Medicine

An extremely rare case of congenital oesophageal stenosis in a two-month-old, male, miniature pincher dog was reported. The puppy was presented at the Small Animal Teaching Hospital, Faculty of Veterinary Science, Chulalongkorn University, with a history of an acute onset of regurgitation at the time of weaning on to solid food. Contrast radiography of the oesophagus showed that the oesophagus at the cervical and thoracic-inlet portions was moderately dilated. Upon oesophagoscopic examination, the oesophageal lumen adjacent to the heart base showed intraluminal stenosis. The mucosa was normal and the stenotic opening was localized at the center of the lumen. Upon …

Localization Of Period 1 Mrna In The Ruminant Oocyte And Investigations Of Its Role In Ovarian Function, R. A. Cushman, M. F. Allan, S. A. Jones, Gary P. Rupp, S. E. Echternkamp

School of Veterinary and Biomedical Sciences: Faculty Publications

The clock gene Period 1 (Per1) may be a prolificacy gene, because it localized to the mouse oocyte and Per1-null drosophila shed fewer eggs. Because Per1 mapped to a region of mouse chromosome 11 syntenic to bovine chromosome 19 where a quantitative trait loci (QTL) for ovulation rate existed, we hypothesized that Per1 influenced folliculogenesis and ovulation rate in ruminants. Ovarian cortex was collected at slaughter on days 5, 12, 15, 17, and 20 after estrus for real-time RT-PCR evaluation of Per1mRNAexpression in Dorset (n = 18), Romanov (n = 10), Romanov/Dorset (n = 21), and Composite …

Veterinary Science Faculty Publications

BACKGROUND: Cytosine-phosphate-guanosine oligodeoxynucleotide (CpG-ODN) has been used successfully to induce immune responses against viral and intracellular organisms in mammals. The main objective of this study was to test the effect of CpG-ODN on antigen presenting cells of young foals.

METHODS: Peripheral blood monocytes of foals (n = 7) were isolated in the first day of life and monthly thereafter up to 3 months of life. Adult horse (n = 7) monocytes were isolated and tested once for comparison. Isolated monocytes were stimulated with IL-4 and GM-CSF (to obtain dendritic cells, DC) or not stimulated (to obtain macrophages). Macrophages and DCs …

Managing Bovine Tuberculosis In White-Tailed Deer In Northwestern Minnesota: A 2007 Progress Report, Michelle Carstensen, David Pauly, Michael Doncarlos, Lou Cornicelli

Michigan Bovine Tuberculosis Bibliography and Database

Bovine tuberculosis (TB), first discovered in 2005, has now been found in 11 cattle operations in northwestern Minnesota. To date, all of the infected cattle herds have been depopulated and the Board of Animal Health (BAH) has continued an investigation of herds in the area as well as conducted a statewide surveillance effort. The strain has been identified as one that is consistent with bovine TB found in cattle in the southwestern United States and Mexico. In November 2007, the Minnesota Department of Natural Resources (MNDNR) conducted bovine TB surveillance of hunter-harvested white-tailed deer (Odocoileus virginianus) within a …

The Pet Food Recall Puzzle: Who, What, Why, And How Much, Roxanne Greitz Miller

Education Faculty Articles and Research

Last spring, North America was gripped in the largest pet food recall in history. News outlets reported tens of thousands of dogs and cats becoming ill, and many dying, as a result of ingesting contaminated pet food. Several pet owners have filed lawsuits against the manufacturers and distributors of the pet food products. I think this is an excellent real-life science story to use with students to show science investigation in action, and to discuss the intersections between the role of regulatory agencies and the public.

In order to understand the case, you first have to know the facts. We'll …
