ABSTRACTThe role of wildlife species in the epidemiology of paratuberculosis has been the subject of increased research efforts following the discovery of natural paratuberculosis in free-living rabbits from farms in east Scotland. This paper describes the experimental inoculation of young calves with an isolate ofMycobacterium aviumsubsp. paratuberculosisrecovered from a free-living rabbit. After a 6-month incubation period, all eight calves inoculated with the rabbit isolate had developed histopathological and/or microbiological evidence of M. aviumsubsp. paratuberculosisinfection. Similar results were obtained from a group of calves infected with a bovine isolate of M. aviumsubsp. paratuberculosis. The virulence of the rabbit isolate for calves demonstrated in this study suggests that rabbits are capable of passing paratuberculosis to domestic ruminants and that wildlife reservoirs of M. aviumsubsp. paratuberculosisshould therefore be considered when formulating control plans for the disease. |
