Mycobacterium avium subsp paratuberculosis was isolated from two out of seventy samples (2.86 %) of pasteurized and ultra-pasteurized milk. The isolates were positives to IS900 PCR and showed a C17 RFLP pattern, the most prevalent in Argentina. The present study is the first report of Mycobacterium avium subsp paratuberculosis culture from pasteurized milk in Argentina.
