A total of 101 isolates of S. aureus collected from the groin, conjunctival sacs, nares and anuses of healthy cats between January 2013 and November 2014 were screened for the presence of antibiotic-resistance genes and phenotypic resistance using the disc diffusion method. More than 80% of S. aureus isolates contained antimicrobial-resistance genes such as: blaZ (100%), ermA (92.08%), ermB (95.05), aac(6’)Ie-aph(2”)Ia (84.16%), tet(K) (98.02%) and tet(M) (84.16%). The presence of mecA gene was detected in 29.7% while only 3.96% were resistant to cefoxitin. About 57% of all isolates in cats showed phenotypic resistance to penicillin. Tetracycline, erythromycin and clindamycin resistance were detected in 7.9%, 15.8% and 9.9% of isolates respectively. Multidrug resis­tance, according only to the results of the disc diffusion method, was observed in 5 isolates (5.0%%) whereas a significantly larger number of multidrug-resistant strains were obtained using the molecular method (99%). We observed that cats, that had received chemotherapeutics over the course of the previous 12 months, were significantly more frequent carriers (p = 0.015) of the multidrug-resistant phenotype of S. aureus isolates. The report shows that healthy cats may serve as reservoirs of antimicrobial-resistant S. aureus strains that harbour resistance genes also found in isolates from humans.}, year = {2016}, journal = {Berliner und Münchener Tierärztliche Wochenschrift}, volume = {129}, month = {10/2016}, publisher = {Schlütersche Verlagsgesellschaft mbH & Co.
