Vana and Vanb Positive Vancomycin-Resistant Staphylococcus Aureus among Clinical Isolates from Cats and Dogs

Article excerpt

Background: Staphylococcus aureus is one of the most com- mon nosocomial and community-acquired infections world- wide. Vancomycin is still preferred for treatment of methicil- lin-resistant S. aureus (MRSA) infections. The purpose of this study was to determine the prevalence of vancomycin- resistant Staphylococcus aureus isolated from among clinical Iso- lates from Cats and Dogs.

Methods: From March to December 2012, 100 S. aureus isolates (mainly from wound and Skin) were collected from two veterinary clinics in southern Iran. After identification of Staphylococcus aureus by biochemical, microbiological and mo- lecular methods, antibiotic susceptibility testing was per- formed by Kirby-Bauer disc diffusion test for 13 different antibiotics. Vancomycin-resistant Staphylococcus aureus isolates were determined by vancomycin agar screening test and PCR for vancomycin resistant genes (i.e. vanA and vanB).

Results: The lowest and highest resistance was seen for qui- nupristin-dalfopristin (n = 1) and ampicillin (n = 95), respec- tively. …
