A cross-sectional study was undertaken to determine the prevalence and distribution of Salmonella serotypes from apparently healthy slaughtered sheep and goats from November 2002 to May 2003 at Debre Zeit abattoir, Ethiopia. From a total of 107 slaughtered animals (60 goats and 47 sheep), 642 sample...

In the summer of 1999, the incidence of Salmonella enterica serotype infantis infections in Alberta rose dramatically. Subsequent laboratory and epidemiological investigations established that an outbreak of human disease caused by this organism was occurring across Canada and was associated with pe...

Canadian Food Inspection Agency (CFIA) has adopted the term cyanosis to describe a category of condemnation for poultry that is dark but has no other condemnable lesions. Two case-control studies (n = 30 pairs; n = 65 pairs) of 18-wk-old tom turkeys were conducted. A case was defined as a carcass co...

Ninety-five Escherichia coli isolates from bovine mastitis, 47 isolates from milking machine filters, 36 enterotoxigenic (ETEC) and 43 verocytotoxigenic (VTEC) isolates from cows were examined for the ability to resist the bactericidal effects of 90% gnotobiotic calf serum. There was no significant ...

Twenty-five strains of Corynebacterium pseudotuberculosis isolated from lesions of caseous lymphadenitis in goats were examined for their biochemical characteristics, antimicrobial susceptibility, and phospholipase D activity. The strains were uniform in biochemical reactions, cultural characteristi...

A study of the causative agents of enteritis in domestic rabbits from 44 different accessions is described. In descending order of frequency, the organisms most commonly demonstrated were intestinal and hepatic coccidia (Eimeria species), Escherichia coli, Clostridium spp., Salmonella, Bacillus pili...

Among grow-to-finish pigs from 10 herds in Alberta and Saskatchewan, 23 (16%) of 144 fecal samples were culture-positive and 40 (28%) of 144 pigs were seropositive for Salmonella. With a Bayesian model specifying dependence between the 2 tests, the sensitivity (Se) of culture and real-time polymeras...

One indication for referral of horses to veterinary hospitals is for diagnosis of the microbiologic cause of pneumonia, particularly when the initial treatment fails. Although endoscopic methods have long been available for microbiologic sample collection, accuracy of these methods under these condi...

The present study was undertaken to determine the occurrence, distribution and antimicrobial resistance pattern of Salmonella serovars in apparently healthy slaughtered sheep and goats in central Ethiopia. A total 1224 samples consisting of faeces, mesenteric lymph nodes, liver, spleen, and abdomina...

Antibodies to seven antigens in a whole cell lysate of Corynebacterium pseudotuberculosis ranging in molecular mass from 22 to 120 kilodaltons (kDa) were present in sera of 40 sheep and goats infected with C. pseudotuberculosis. Three antigens of about 120, 68, and 31.5 kDa in size were consistently...

Efficacy of sulbactam, a beta-lactamase inhibitor, in combination with ampicillin, was evaluated for treatment of experimentally induced pneumonia caused by beta-lactam-resistant Klebsiella pneumoniae. Infection was experimentally induced in 18 healthy weanling foals that were randomly allocated to ...

An antibody microarray assay was developed for Salmonella serotyping based on the Kauffmann-White scheme. A model (8 by 15) array was constructed using 35 antibodies for identification of 20 common Salmonella serovars and evaluated using 117 target and 73 nontarget Salmonella strains. The assay allo...

Antibodies to 7 antigens in a whole cell lysate C. pseudotuberculosis ranging in molecular mass from 22 to 120 kDa were present in sera of 40 sheep and goats infected with C. pseudotuberculosis. Three antigens of about 120, 68 and 31.5 kDa in size were consistently detected with sera from all animal...

In vitro methods were used to test the hypothesis that Escherichia coli from bovine mastitis are essentially no different from isolates from bovine feces. Fifty E. coli isolates from bovine mastitic milk, 50 from feces of mastitic cows and 50 from feces of healthy cows were compared with respect to ...

In order to describe the farm-level Salmonella status, 113 Ontario swine farms were tested for Salmonella one to five times within the time period 2001-2006. During 422 visits, 6844 fecal samples were collected and cultured for Salmonella. Salmonella was recovered from 437 (6.38%) of the fecal sampl...

A novel method to reduce contamination of the bronchoscope during microbial sampling of the lower airways of foals was evaluated. Methylene blue (MB) was used as a nasopharyngeal dye marker to assess the relative contamination from the upper airways of bronchoalveolar lavage (BAL) specimens obtained...

Raw and pasteurized milk samples submitted for routine quality analysis were screened for the presence of B. cereus diarrhoeal enterotoxin (BDE) using the TECRA BDE visual immunoassay (VIA) kit. BDE was not detected in 298 raw milk samples tested by the TECRA VIA. B. cereus was isolated from 2 of 29...

The Sceptor system (Becton Dickinson Diagnostic Instrument Systems, Towson Md.) was assessed for its ability to identify veterinary clinical isolates. A total of 605 bacteria, including 315 isolates of the family Enterobacteriaceae, 191 gram-negative nonenteric bacteria, and 99 gram-positive bacteri...

The present study was undertaken to estimate the occurrence and distribution of multidrug resistance (MDR) among Salmonella serovars isolated from slaughtered pigs at Debre Zeit, Ethiopia. A total of 501 different samples were examined of which 42 (41.6%) of 101 mesenteric lymph nodes, 22 (21.8%) of...

The aim of this study was to determine the farm prevalence of Salmonella in 90 Alberta finishing swine farms over a 5-month period, to evaluate Salmonella distribution in the farm environment and to describe Salmonella serovar diversity on these farms. Ten veterinary practitioners selected 90 Albert...
