Presence of Enterococci in Cats with Urinary Tract Infections and Antibiotic Resistance Profiles

Abstract: Background: Bacterial urinary tract infection (UTI) is one of the most common diseases in cats caused by an imbalance between the natural host defence mechanisms of the urinary tract and virulent bacteria. This study investigated the prevalence and antimicrobial susceptibility of enterococci isolated from cats presenting urinary tract problems to veterinary clinics in Istanbul. Methods: 100 urine samples were collected from cats by cystocentesis and plated on blood agar. Isolates found catalase and oxidase negative plated on Enterococcocel agar. After incubation, the isolates formed black colonies were tested by PCR using E. faecium and E. faecalis-specific primers. Then the antibiotic susceptibility of the isolates was determined. Result: Eight of the 100 isolates that formed black colonies on Enterococcosel agar were identified as Enterococcus spp. After PCR tests, six isolates were classified as E. faecalis, one isolate was classified as E. faecium and one isolate that did not form a band was classified as Enterococcus spp. As a result of the Kirby-Bauer disc diffusion method used to determine the antibiotic susceptibility of the isolates, most resistance was found to cephalothin (100%) and penicillin, erythromycin, clindamycin and tetracycline (87.5%). While vancomycin resistance was not observed in any isolate, the lowest resistance was to enrofloxacin and ciprofloxacin (33.3%). Multiple antibiotic resistance was observed in all (100%) isolates. The presence of multi-resistant enterococci in cats represents a significant health threat. Bacterial identification and antimicrobial susceptibility testing should always be performed in urinary tract infections to guide definitive diagnosis and treatment.
