Antimicrobial susceptibility of vancomycin resistant enterococcus species isolated from urinary system of DOGS

The purpose of the present study was to determine the antimicrobial susceptibility of vancomycin-resistant Enterococcus faecalis ve Enterococcus faecium strains isolated from urine samples of dogs. In this context, a total of 22 Enterococcus spp samples were isolated and identified from 100 urine samples collected by cystocentesis from dogs of both sexes presented to Aydın Adnan Menderes University Faculty of Veterinary Medicine Research and Practice Hospital, Departments of Internal Medicine and Surgery. Identification of isolates with using species specific primers of multiplex PCR revealed that 22 (100%) of urine origin Enterococci strains as E. faecium whereas E. faecalis isolates were not observed. Vancomycin resistance were found in 10 (45%) samples of E. faecium strains with PCR study by vanA and vanB primers. Isolates were found susceptible 100 % to ampicillin and tigecycline, 36% to tetracycline, 18% to clindamycin and resistant 100% to ceftriaxone with antibiotic susceptibility testing by E-test.
