Detection of Staphylococcus pseudintermedius resistant to methicillin and to other antimicrobials commonly used in canine pyodermias
Ninety-six samples from dogs with different clinical forms of pyodermia were studied, withthe objective of detecting the presence of Staphylococcus pseudintermedius by phenotypic tests andthe antimicrobial resistance to methicillin and other antimicrobials commonly used in clinical practice.S. pseudintermedius was identified in 91 animals (94.8 %) and methicillin resistance was detectedin 31 strains (34 %). Of these, 21 (93.5 %) expressed multiresistance to 4, 5 and 6 antimicrobials.The predominant resistance profile was OXA-ERY-CLIN-TMS-CIP-CMP. Among other antibioticstested, the ones with the highest percentage of resistance were: trimethoprim-sulfamethoxazole (67%), erythromycin (64.4 %), clindamycin (60 %) and ciprofloxacin (52 %). All strains were sensitive tovancomycin, nitrofurantoin and rifampicin. The D-test was performed to evaluate inducible resistanceto clindamycin. It is concluded that the phenotypic identification of S. pseudintermedius as well asthe antibiogram are important tools to contribute to the responsible use of antimicrobials in veterinary medicine.
