clinical significance of nontuberculous mycobacteria isolates in a canadian tertiary care determine the epidemiology and clinical features of disease due to nontuberculous mycobacteria (ntm) in our institution, we reviewed the medical records of all patients from whom ntm isolates were recovered from 1988 to 1990 to extract selected clinical and laboratory data. on the basis of the likelihood of infection, patients were classified as having definite, probable, or unlikely ntm disease as defined by published guidelines. of 80 patients who met the inclusion criteria, 17 had definite ...19957578721
attitudes of canadian dairy farmers toward a voluntary johne's disease control program.the success of johne's disease (jd) control programs based on risk assessment (ra) depends on producers' compliance with suggested management practices. one objective of this study was to describe the perception of participating canadian dairy farmers of the impact of jd, the ra process, and suggested management strategies. the second objective was to describe the cost of changes in management practices following the ra. a telephone survey was conducted with 238 dairy farmers in ontario, manitob ...201020338426

feasibility of using coyotes (canis latrans) as sentinels for bovine mycobacteriosis (mycobacterium bovis) infection in wild cervids in and around riding mountain national park, manitoba, canada.elk (cervus elaphus manitobensis) and white-tailed deer (odocoileus virginianus) in the riding mountain national park (rmnp) region of southwestern manitoba have been identified as a likely wildlife reservoir of mycobacterium bovis, the causative agent of bovine mycobacteriosis in livestock. the feasibility of using coyotes (canis latrans) collected from trappers as a sentinel species was investigated. retropharyngeal, mesenteric, and colonic lymph nodes and tonsils collected at necropsy from 82 ...200717699081
study of animal-borne infections in the mucosas of patients with inflammatory bowel disease and population-based controls.crohn's disease may be triggered by an infection, and it is plausible to consider that such an infection may be animal borne and ingested with our food. there has been considerable interest in the past in determining whether mycobacterium avium subsp. paratuberculosis (m. avium) might be the etiologic agent in crohn's disease since it causes a disease in cattle that is similar to crohn's disease in humans. we aimed to determine if there was an association between crohn's disease and infection wi ...200314605128
