Abstract

Johne's disease can be an economically devastating disease on dairy farms. Current risk assessment (RA)-based control programs use best management practices to prevent the transmission of the causative pathogen, Mycobacterium avium subsp paratuberculosis (MAP), between animals. Most effort is focused on the fecal-oral route of transmission between infectious dams and calves. Because MAP has been isolated from water troughs, the objective of this pilot study was to determine whether MAP can be detected in the saliva (a previously overlooked route of transmission) of infected cattle.
