ANTIMICROBIAL RESISTANCE OF COMMON UROPATHOGENS FROM CATS WITH URINARY TRACT INFECTIONS IN A VETERINARY TEACHING HOSPITAL IN TAIWAN

摘要

Urinary tract infection (UTI) is frequently diagnosed in dogs and cats. To realize common regional uropathogens and their antimicrobial resistance plays an important role in both human and veterinary medicine. An empirical antibiotic was administrated while waiting for the results of bacterial culture and antimicrobial susceptibility testing. Eighty-five bacterial isolates were obtained from 74 cats with clinical signs of UTI. Escherichia coli, Enterococcus species, Staphylococcus species and Klebsiella species were the most common bacterial isolates in our hospital. Compared to the previous researches, the susceptibilities of recommended empirical antibiotics exhibited higher resistant rate in our study. Lincomycin was the most resistant antibiotic within the test panel to that almost 98% uropathogens were resistant. The resistant rates of cephalexin, cephalothin, penicillin and amoxicillin were about 90%. Therefore, the selection of empirical antibiotics should be re-evaluated with time in Taiwan.
