Material and Methods: In this cross–sectional study, 100 raw milk samples of cows were collected from both industrial and semi -industrial farms in shahre-kord. The DNA of all Samples was isolated by MAP, using PCR method. Results: The results Show that only three (3%) Samples were positive for Mycobacterium avium subsp. paratuberculosis.
