Indian isolates of Mycobacterium avium subspecies paratuberculosis (MAP) from cattle (5) and goats (4) were characterised by pulsed-field gel electrophoresis (PFGE) and polymerase chain reaction (PCR) and profiles were compared with standard strains. All isolates were found to have IS 900 and F57 genes. PFGE analysis with SnaBI revealed that the profiles of the cattle and goat isolates were identical and had a unique profile when compared with profiles currently in the PFGE database. PFGE analysis with SpeI demonstrated that all of the isolates were identical to SpeI profile 1 in the database. It was concluded that Indian isolates from cattle and goats were genetically similar but different from European strains.
