The objective of this study was to describe the distribution of Salmonella spp. on Ontario grower-finisher pig farms. Eighty swine farms were visited from January through July 2004. On each farm, fecal samples were collected from 5 pens, 2 rectal samples and 1 pooled sample from fresh manure on the ...

The study objectives were to investigate Salmonella prevalence, serovar distribution, and risk factors for shedding in 10 purposively selected farrow-to-finish farms in Saskatchewan and Alberta. Pooled fecal samples from the breeding and growfinish phases and individual fecal samples from breeding, ...

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...

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...

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 ...

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...

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...

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...

Raw river and irrigation water in the Oldman River Basin in southern Alberta was tested for the presence of two bacterial pathogens, Escherichia coli O157:H7 and Salmonella spp., over the last two years (2000-01). The number of E. coli O157:H7 and Salmonella spp. isolated from raw water peaked durin...

Two goat flocks comprising 326 animals and four sheep flocks comprising 343 animals, all with a previously recognized problem of abscesses due to Corynebacterium pseudotuberculosis, were examined for the presence of abscesses and antibody titers to C. pseudotuberculosis as detected by direct microag...

A cross-sectional study was undertaken to determine the prevalence and distribution of Salmonella serotypes in minced meat beef, mutton and pork from retail supermarkets in Addis Ababa, Ethiopia. A total of 300 samples (160 minced beef, 85 mutton and 55 pork) were collected from November 2002 to Apr...

We looked for Salmonella in all 278 apparently healthy pigs slaughtered between September 2004 and May 2005 at the only pig-slaughtering slaughterhouse in Addis Ababa, Ethiopia. We used standard methods and tested caecal contents, mesenteric lymph nodes, and carcass swabs from each pig (missing only...

The present study was undertaken to determine the occurrence, distribution and antimicrobial resistance profiles of Salmonella serovars in slaughter beef cattle, slaughterhouse environment and personnel engaged in flaying and evisceration during slaughtering process. A total of 800 samples (each sam...

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...

Cloacal and pharyngeal swabs from 100 tree-nesting Double-crested cormorant (DCC) chicks were examined by culture for commensal and potentially pathogenic bacteria. No Salmonella or Erysipelothrix were isolated from the cloacal swabs. Twenty-two cloacal swabs were positive for Campylobacter, of whic...

A 2-year old gelding was referred for evaluation of severe right forelimb lameness. The horse was grade 4/5 lame on the right forelimb. Clinical, laboratory, and radiographic findings were consistent with septic arthritis and osteomyelitis. Due to poor prognosis the owner elected euthanasia. Histopa...

Background Recent focus on earlier detection of pathogen introduction in human and animal populations has led to the development of surveillance systems based on automated monitoring of health data. Real- or near real-time monitoring of pre-diagnostic data requires automated classification of recor...
