serosurvey of coxiella burnetii infection in dairy goat herds in ontario. a comparison of two methods of enzyme-linked immunosorbent assay.two technical variations of enzyme-linked immunosorbent assay for the detection of antibodies to coxiella burnetii were compared in this serosurvey on 20 ontario dairy goat herds. both a trichloracetic acid extract and a coctoantigen of purified coxiellas were used to sensitize the microtitration plates. technical differences related to coating ph, serum dilutions tested and interpretation of results. results agreed in 98.6% of sera examined, the differing sera were in the low titer borderline r ...19883349400
rate of campylobacter spp. isolation in three regions of ontario, canada, from 1978 to 1985.isolation rates of campylobacter spp. were analyzed for an 8-year period, 1978 through 1985. three laboratories of the ontario ministry of health examined 146,842 human feces samples for bacterial pathogens, including campylobacter jejuni and campylobacter coli. campylobacter spp. were isolated from 5,580 specimens (3.8%), with monthly isolation rates ranging from 1.1 to 7.4%. the data showed a seasonal distribution of isolations, with peaks during the summer months (june to september). most inf ...19863771774

listeria monocytogenes infections in canada.since its first isolation by murray in 1926 listeria monocytogenes has become recognized as a significant pathogen occurring worldwide and involving a wide range of wild and domestic animals including man. the first confirmed human listeriosis case in canada was published by stoot in 1951. a later survey based on records maintained at the laboratory centre for disease control, ottawa showed 101 cases detected over a 21 year period in nine provinces. the overall mortality was 30%. the most freque ...19846442654
susceptibility of goats and calves after experimental inoculation or contact exposure to a canadian strain of mycoplasma mycoides subsp. mycoides isolated from a goat.transmissibility of mycoplasma mycoides subsp. mycoides infection from experimentally inoculated goats to other goats and calves was studied. eight goats and six calves were housed in an 18 m2 room. six of the goats were inoculated endobronchially with strain d44 isolated from a natural case of polyarthritis in ontario. these six goats died within a week of mycoplasma septicemia. the two contact goats or the six calves never showed signs of disease and m. mycoides subsp. mycoides was not recover ...19836365296
experimental studies on the pathogenicity of mycoplasma ovipneumoniae and mycoplasma arginini for the respiratory tract of goats.mycoplasma ovipneumoniae and mycoplasma arginini were the species of mollicutes most commonly isolated from 175 goats with respiratory disease in ontario. the pathogenicity of m. ovipneumoniae, strain b321b and m. arginini, strain d53e, was assessed in goats following endobronchial inoculation. one out of three two year old goats developed fever after inoculation with a pure culture of strain b321b, and it had extensive subacute fibrinous pleuritis when necropsied three weeks later. neither of t ...19863742358
unsolved problems of the goat industry.a few of the challenges to successful goat farming have been mentioned. the veterinary practitioner is a pivotal specialist whose expertise and services could greatly improve productivity in all types of goat production, particularly because productivity appears to be limited mainly by disease. in my opinion, goat producers are, for the most part, trying to struggle on without us. this, i believe, is an unfortunate reflection of our failure to make them aware of how helpful we can be when invite ...19902245375

an immunoprecipitin study of the incidence of influenza a antibodies in animal sera in the ottawa area.a survey of over 600 'normal' sera from 14 animal species by immunoprecipitin tests in cellulose acetate using viron antigens revealed a high incidence of precipitating activity against a broad range of influenza a virus strains, particularly a2hhong kong/1/68 and /pr8. however, serum treatments trypsin-heat-periodate, naio4, v. cholerae receptor-destroying enzyme (rde), or kaolin eliminated most precipitating activity, which suggests that it was due to "non-specific" inhibitors of influenze vir ...1975167931
