title: Mycobacterial infection of pigs in Croatia.
abstract: During a five-year period (2000 to 2004) 74,342 pigs were tested by the intradermal tuberculin test in Croatia. Of them, 248 (0.33%) pigs were positive and 91 (0.12%) were found to be suspicious in 7 out of the 13 farms included in the study. Gross pathological changes characteristic of tuberculosis were observed in tuberculin-positive and/or suspicious swine. Mycobacterium was isolated from the lymph nodes of 183 out of 234 swine (78.2%). For better epidemiological understanding, isolates were typed by conventional methods, PCR and hybridisation. The results show that most of the isolates belonged to the Mycobacterium avium complex (175 isolates, 95.7%). Other isolates belonged to M. fortuitum (6 isolates, 3.3%), M. chelonae (1 isolate, 0.5%), and M. peregrinum (1 isolate, 0.5%). Isolated strains of the M. avium complex were identified as M a. avium (37 isolates, 21.1%) and M. a. hominissuis (138 isolates, 78.9%).
