The Change in Antimicrobial Resistance Profile of Meat Chain-associated Salmonella in Serbia

This study aimed to monitor antimicrobial resistance trends of Salmonella isolated from meat production chains. A total of 5759 samples were examined for Salmonella presence and antimicrobial resistance. Salmonella species were isolated from 86 samples: (1.49%), 41 of these serotypes were S. Enteritidis (47.67%), 24 were S. Infantis (27.91%). In 2007, resistance in Salmonella was most frequently to amoxicillin and sulfametoxazol. In 2013-2014 we detected significant resistance of S. Infantis to nalidixic acid and tetracycline. The results detected a national trend in S. Infantis resistance – the change of antimicrobial resistance profile.
