Evidence of passive faecal shedding of Mycobacterium avium subsp paratuberculosis in a Limousin cattle herd

Original language description

It has been suggested that passive shedding of Mycobacterium avium subsp. paratuberculosis (MAP) in faeces may occur, but reliable data are missing. Passive shedding assumes the ingestion of MAP in contaminated feed and passive passage through the gastrointestinal tract without causing infection. In this study the presence of MAP in faeces in a closed herd of Limousin cattle was monitored for 53 months using quantitative real time PCR (qPCR) and culture. The initial prevalence of MAP in the herd was determined to be 63.4% and 4.9% using qPCR and culture, respectively. After the removal of two culture- and qPCR-positive (>10(4) MAP cells/g) cows, the prevalence of MAP using qPCR decreased to 42.1% and later to 15.6% and 6.7%. The continuous removal of suspected animals from the herd during the monitoring period minimised the presence of MAP in faeces to sporadic, which may have resulted from a decrease in the environmental infectious pressure. The findings suggest that the presence of l
