Mycobacterium avium subsp. paratuberculosis (MAP) isolated from animals in Jordan. In this study, we investigated 150 fecal samples from sheep, goats, and cattle for the presence of paratuberculosis using bacterial culture and polymerase chain reaction (PCR)-RFLP analysis of insertion sequence IS 1311. Analysis of the results revealed that genotypic information from sheep, goat, and cattle could classify them into cattle or sheep strains. All culture isolates from cattle, 12.5% of the isolates from sheep, and 50% of the isolates from goats were cattle strain, while 87.5% of the isolates from sheep and 50% of the isolates from goats were sheep strain. Sequencing of the IS 1311 268 bp PCR product from the three animal species confirmed the different MAP patterns.
Paratuberculosis is an endemic disease and induces high economical losses in Jordan. There is no information available on genotypic variation of
