| an assessment of residual ovine nematodes on pasture under maritime conditions. | residual ovine nematode pasture infections were assessed by grazing groups of ewes and their lambs on permanent sheep and cattle pastures and by the use of tracer lambs. ostertagia spp., cooperia oncophora, nematodirus spp., chabertia ovina and trichuris spp. eggs and/or larvae survived on pastures overwinter. second generation ostertagia larvae were present in greatest numbers on pasture during the latter part of august and early september. the failure of a significant build-up of cooperia onco ... | 1989 | 2766155 |
| exposure to parturient cats: a risk factor for acquisition of q fever in maritime canada. | over a 34-mo period we studied 51 patients with q fever and 102 control subjects (with various lower-respiratory-tract infections) who were matched for age, sex, and time of onset of infection. by univariate analysis (not adjusted for multiple comparisons), cases differed significantly from controls in the following activities: working on a farm; slaughtering or dressing animals; and contact with cats, cattle, and sheep. the strongest association was with exposure to stillborn kittens--11 of 51 ... | 1988 | 3392409 |

| highly presumptive identification of bacterial isolates associated with the recent canada-wide mastitis epizootic as nocardia farcinica. | a highly presumptive identification of nocardia farcinica was made of 47 bacterial isolates. fifteen isolates from alberta, 9 from ontario, and 2 each from new brunswick, newfoundland, and nova scotia were from clinical cases involved in the canadian mastitis epizootic. seventeen additional isolates from alberta were recovered from farm milk bulk tanks from herds found to have cows involved in the epizootic. all isolates were shown by high-performance liquid chromatography to possess mycolic aci ... | 1993 | 8364799 |
| neospora then and now: prevalence of neospora caninum in maritime canada in 1979, 1989, and 1998. | the seroprevalence of neospora caninum was compared among new brunswick, nova scotia, and prince edward island in 1998, 1989, and 1979. in 1998, the seroprevalence was lowest in prince edward island, where it was the same as in 1989. neospora caninum was present in 1979, but at a lower prevalence. | 2000 | 11126492 |
| seroprevalence of infection with mycobacterium avium subspecies paratuberculosis, bovine leukemia virus, and bovine viral diarrhea virus in maritime canada dairy cattle. | the purpose of this study was to survey the seroprevalence of infection with the agents of production-limiting diseases in dairy cattle in new brunswick, nova scotia, and prince edward island. in 30 randomly selected herds per province, 30 cattle per herd were randomly selected and tested for antibodies to bovine leukemia virus (blv) and mycobacterium avium subspecies paratuberculosis (m. paratuberculosis), while 5 unvaccinated cattle over 6 months of age were tested for antibodies to bovine vir ... | 2001 | 11265187 |
| q fever in canada. | a canada-wide survey of q fever was begun in 1958 in co-operation with public health and veterinary laboratories to determine the presence and prevalence of the disease so that medical practitioners might be alerted to the potential dangers existing. serologic evidence obtained indicated that the q fever rickettsia now exists in cattle in all provinces of canada except new brunswick, nova scotia, and prince edward island. isolations of the rickettsia were obtained from bovine milk samples from o ... | 1964 | 14175873 |

| short communication: extended-spectrum cephalosporin-resistant escherichia coli in colostrum from new brunswick, canada, dairy cows harbor blacmy-2 and blatem resistance genes. | dairy calves are colonized shortly after birth by multidrug resistant (mdr) bacteria, including escherichia coli. the role of dairy colostrum fed to calves as a potential source of mdr bacteria resistance genes has not been investigated. this study determined the recovery rate of extended-spectrum cephalosporin-resistant (esc-r) e. coli in colostrum from cows. the esc-r e. coli isolates were further investigated to determine their phenotypic antimicrobial resistance pattern and the genes conferr ... | 2017 | 28780105 |
