Mycobacterium avium subspecies paratuberculosis, the etiologic agent of Johne's disease or paratuberculosis, was identified by culture and/or polymerase chain reaction (PCR) in 50% and 30% of water samples for animal and human consumption, respectively, from ten dairy goat farms in Brazil. IS1311 restriction fragment length polymorphism analysis identified the isolates as cattle type C.
