Zoonoses are infections that are transmissible between animals and humans. In recent decades zoonotic bacteria resistant to antimicrobials became of special concern since they might compromise the effective treatment of infections in humans. Resistance is mediated via mobile genetic elements such as plasmids, transposons or genomic islands. During the 2-year period of monitoring of hygiene in selected Serbian slaughterhouses, a total of 49 Salmonella spp. strains were collected from cattle carcasses. Strains were subjected to testing of resistance to commonly used antimicrobials, such as tetracycline, ampicillin, gentamycin, chloramphenicol, nalidixic acid, ciprofloxacin and sulphonamides. The most of tested samples were resistant to tetracycline, ampicillin, chloramphenicol and sulphonamides, while just a few were resistant to gentamycin and quinolones which are defined as critically important antimicrobials in human medicine. Obtained results are similar to results of antimicrobial resistance patterns reported by other EU countries indicating how uncontrolled usage of cheap and easy available antimicrobials led towards an onset of the resistance. Monitoring of Salmonella is mandatory in humans in accordance with the provisions of Commission Decision 2000/96/EC on the communicable diseases to be progressively covered by the Community network, and in food and animals in accordance with the provisions of Directive 2003/99/EC on the monitoring of zoonoses and zoonotic agents.
