Resumen

Ninety-six methicillin-susceptible Staphylococcus aureus (MSSA) and 11 methicillin-resistant coagulase-negative staphylococci (MRCNS) were recovered from food of animal origin. Multi-drug resistance was detected in 34.1% of isolates. Tetracycline-resistant staphylococci harbored tetK gene (68.8%). Erythromycin/clindamycin-resistant staphylococci carried lnuA/lnuB genes frequently alone or combined with msrA gene. The sec gene was detected in 15.6% of MSSA and two isolates harbored the immune evasion cluster. The spa t337 predominated among MSSA strains. Two ermC-positive MRCNS isolates were observed, five mecA-positive carried SCCmec IVa and 6 were non-typeable by the IWG-SCC classification. These results demonstrate that food of animal origin can be a potential source for spreading of multidrug-resistance gene. © 2018 Association of Microbiologists of India
