Highly toxigenic as well as hypotoxigenic strains of Clostridium botulinum type C were isolated from 8 of 73 soil samples obtained from an avian botulism endemic area in Ontario. Amongst wild birds a high proportion of healthy pheasants carried the organism in their digestive tracts. One-third of th...

Twenty strains of Clostridium botulinum type C, including 12 isolates from avian sources with varying toxigenic properties, were examined by electron microscope for the presence of bacteriophages. All toxigenic strains were infected with one or two types of phages. Three types of phages designated l...

We report a rapid competitive enzyme-linked immunosorbent assay to screen Salmonella typhimurium strains for cholera-related enterotoxin antigens. Polymyxin B extracts of bacterial cells from syncase-glucose broth cultures of 7 of 15 strains gave positive results. The specificity of the test was con...

Twenty-five strains of Salmonella typhimurium isolated in India were examined for the presence of cholera/coli-related enterotoxin antigen by a previously described latex particle agglutination test and by a newly developed immuno-dot-blot test using immunopurified goat antibody against the cholera-...

The in vitro susceptibility of a total of 1819 bacterial isolates from canine and 103 isolates from feline otitis externa cases to 13 antimicrobial drugs over a 5-year period was evaluated. Among topically used drugs, 90% of isolates were susceptible to gentamicin. Susceptibility of Pseudomonas aeru...

Fifty-nine Streptococcus suis type 2 isolates, recovered from pigs originating from Prince Edward Island, Canada, were tested for their susceptibility to eight antimicrobial agents by a disc diffusion method. All of the isolates were susceptible to penicillin and ampicillin. One third of isolates we...

Fourteen human isolates of Campylobacter jejuni (13 pathogenic + 1 non-pathogenic) and two animal isolates were studied for the production of a toxin immunologically related to the heat-labile enterotoxin (LT) produced by a strain of Escherichia coli of human (H) origin using an immuno-dot-blot assa...

Forty human isolates and twenty-eight animal isolates of Pseudomonas aeruginosa from Prince Edward Island area (Atlantic Canada) were serotyped using a kit consisting of 4 polyvalent O-group antisera and 17 monovalent O-type (serovar) antisera, in accordance with the International Antigenic Typing S...

Cultural examination of cecal contents from 109 market weight hogs slaughtered in Prince Edward Island during May-July 1988 yielded 62 isolates of Campylobacter coli and seven Campylobacter jejuni. A commercial latex agglutination test helped to confirm the identification of Campylobacter. When test...

A one-step iodophor skin preparation solution was compared to chlorhexidine gluconate application as a pre-operative skin preparation method in 100 animals undergoing elective ovariohysterectomy. Pre-operative and intra-operative skin cultures demonstrated no difference in antiseptic efficacy. No an...

Serum samples from 43 cases of Guillain-Barre Syndrome (GBS), 32 non-GBS neurology patients, and 35 healthy persons from a medical institute in Kerala, India, were tested for antibody levels against a Campylobacter jejuni strain Penner serotype 0:19 by agglutination and ELISA. Twenty-six percent of ...

In vitro resistance to 8 antimicrobials among enterotoxigenic Escherichia coli from piglets and calves over a 13-year period was evaluated. Least resistance occurred against ceftiofur for all, followed by apramycin and gentamicin for porcine and florfenicol for bovine isolates. No significant differ...

During 1978-79 a private colony of rhesus monkeys (Macaca mulatta) were tuberculin tested. Several positive reactions were detected. On PM examination a total of 15 animals, which included reactors as well as in-contacts, showed gross lesions in internal organs. The lungs, spleen and occasionally li...
