Diagnosis of Clostridium Perfringens Intestinal Infections in Sheep and Goats
Journal of Veterinary Diagnostic Investigation - Tập 20 Số 3 - Trang 253-265 - 2008
Francisco A. Uzal, J. Glenn Songer
Clostridium perfringens produces enteric diseases, generically called enterotoxemias, in sheep, goats, and other animals. This microorganism can be a normal inhabitant of the intestine of most animal species, including humans, but when the intestinal environment is altered by sudden changes in diet or other factors, C. perfringens proliferates and produces potent toxins that act locally o...... hiện toàn bộ
Lymphoid Follicular Cloacal Inflammation Associated with a Novel Herpesvirus in Juvenile Alligators (Alligator Mississippiensis)
Journal of Veterinary Diagnostic Investigation - Tập 17 Số 5 - Trang 474-479 - 2005
Pamela Govett, Craig A. Harms, April J. Johnson, Kenneth S. Latimer, James F. X. Wellehan, Michael H. Fatzinger, Larry S. Christian, T. Ross Kelly, Gregory A. Lewbart
Multifocal hyperemic nodules and plaques associated with the cloacal mucosa of juvenile alligators ( Alligator mississippiensis) at a public aquarium were investigated. Grossly, pale pink to dark red multifocal, circular lesions of varying degrees of severity were identified on the cloacal and, in males, phallus mucosa. Cloacal mucosa biopsies were obtained from 2 of the alligators. These...... hiện toàn bộ
Leishmania amastigotes in the central nervous system of a naturally infected dog
Journal of Veterinary Diagnostic Investigation - Tập 25 Số 1 - Trang 142-146 - 2013
M. Márquez, José Raúl Pedregosa, Jesús López, P. Marco-Salazar, Dolors Fondevila, Martı́ Pumarola
A 4-year-old male Labrador Retriever dog was presented with a 10-day history of tetraplegia, depression, and absent postural reflexes. The cerebrospinal fluid was positive for Leishmania spp. DNA. At necropsy, a 2-cm long mass was observed adhered to C7 and C8 left spinal nerves. Microscopically, nerve fiber destruction together with mixed inflamm...... hiện toàn bộ
Sudden death in racehorses: postmortem examination protocol
Journal of Veterinary Diagnostic Investigation - Tập 29 Số 4 - Trang 442-449 - 2017
Santiago S. Diab, Robert H. Poppenga, Francisco A. Uzal
In racehorses, sudden death (SD) associated with exercise poses a serious risk to jockeys and adversely affects racehorse welfare and the public perception of horse racing. In a majority of cases of exercise-associated sudden death (EASD), there are no gross lesions to explain the cause of death, and an examination of the cardiovascular system and a toxicologic screen are warranted. Cases...... hiện toàn bộ
Postmortem findings in Ontario racehorses, 2003–2015
Journal of Veterinary Diagnostic Investigation - Tập 29 Số 4 - Trang 457-464 - 2017
J Delay
Postmortem lesions and cause of death were evaluated retrospectively for 963 horses examined as part of the Ontario Racing Commission Death Registry over a 13-y period. The Death Registry was established in 2003 to identify factors leading to death or euthanasia of racehorses in this Canadian province. Postmortem examination was carried out on 56% of horses reported to the Death Registry a...... hiện toàn bộ
Diagnosis of Oleander Poisoning in Livestock
Journal of Veterinary Diagnostic Investigation - Tập 8 Số 3 - Trang 358-364 - 1996
Francis D. Galey, Dirk M. Holstege, Konstanze H. Plumlee, Elizabeth R. Tor, Bill Johnson, Mark L. Anderson, Patricia C. Blanchard, Frank R. Brown
Since mid- 1989, 37 cases of oleander poisoning in livestock have been diagnosed at the California Veterinary Diagnostic Laboratory System. The most frequent source for oleander exposure was plant clippings. Sudden death was the most common presenting complaint. Other signs reported included diarrhea, pulmonary edema, tachycardia, cardiac arrhythmias, colic, and lethargy. In the past, a p...... hiện toàn bộ
Aflatoxicosis in Nine Dogs after Exposure to Contaminated Commercial Dog Food
Journal of Veterinary Diagnostic Investigation - Tập 19 Số 2 - Trang 168-175 - 2007
Shelley J. Newman, Joanne R. Smith, Kate A. Stenske, Leslie B. Newman, John R. Dunlap, Paula M. Imerman, Claudia A. Kirk
The purpose of this study was to characterize light and electron microscopic findings from 9 dogs that had consumed aflatoxin-contaminated commercial dog food from recalled batches. Four dogs died and 5 were euthanized after signs of liver failure. Analysis of feed and liver samples confirmed exposure to aflatoxin. Of the 9 dogs, 8 had classic signs of liver failure, and 1 had signs of li...... hiện toàn bộ
Case Report and DNA Characterization of Mycobacterium Avium Isolates from Multiple Animals with Lesions in a Beef Cattle Herd
Journal of Veterinary Diagnostic Investigation - Tập 10 Số 3 - Trang 283-284 - 1998

Atypical Transmissible Spongiform Encephalopathies in Ruminants: A Challenge for Disease Surveillance and Control
Journal of Veterinary Diagnostic Investigation - Tập 22 Số 6 - Trang 823-842 - 2010
Torsten Seuberlich, Dagmar Heim, Andreas Zurbriggen
Since 1987, when bovine spongiform encephalopathy (BSE) emerged as a novel disease in cattle, enormous efforts were undertaken to monitor and control the disease in ruminants worldwide. The driving force was its high economic impact, which resulted from trade restrictions and the loss of consumer confidence in beef products, the latter because BSE turned out to be a fatal zoonosis, causin...... hiện toàn bộ
Malignant Catarrhal Fever: Polymerase Chain Reaction Survey for Ovine Herpesvirus 2 and Other Persistent Herpesvirus and Retrovirus Infections of Dairy Cattle and Bison
Journal of Veterinary Diagnostic Investigation - Tập 12 Số 5 - Trang 406-411 - 2000
James K. Collins, Christa Bruns, Tracy L. Vermedahl, Anita Schiebel, Michael Jessen, Patricia C. Schultheiss, Gwen M. Anderson, R. Page Dinsmore, Robert J. Callan, James C. DeMartini
Using a polymerase chain reaction (PCR) test for sequences of ovine herpesvirus 2 (OHV2), this virus was shown to be significantly associated with sheep-associated malignant catarrhal fever (SA-MCF) in terminal cases of disease in 34 cattle and 53 bison. Ovine herpesvirus 2 was not detected in cattle (38) and bison (10) that succumbed to other diseases. Other persistent herpesviruses, ret...... hiện toàn bộ
