Antimicrobial sensitivity of most commonly isolated bacteria from feline upper respiratory infection

Abstract

In cats, upper respiratory tract infection (URI) can be associated with primary or secondary bacterial infection and is generally treated with antimicrobials. Antimicrobial use can be inappropriate, and overuse. There are no detailed protocols for treatment, such as those available for human treatment. This study aimed to determine the antimicrobial sensitivity of the most isolated bacteria in cats that infected with the URI. Isolation and identification of bacteria in samples of cats infected with the URI were then continued with the antibiotic sensitivity test for amoxicillin, doxycycline, tetracycline, azithromycin, ciprofloxacin, and cefotaxime using the Kirby Bauer Agar Disc diffusion method. Based on the research results, the bacteria identified were Enterobacter spp, Streptococcus spp, Staphylococcus spp, Pseudomonas spp, Serratia spp, Yersinia spp, Micrococcus spp, Klebsiella spp and Hafnia spp. Amoxicillin antibiotic resistance was found in four isolates of Staphylococcus spp and two isolates resistant to cefotaxime. Amoxicillin and tetracycline antibiotic resistance were found in one isolate of  Streptococcus spp, two isolates resistant to cefotaxime and two intermediate isolates to doxycycline. One isolate of Enterobacter spp was resistant to amoxicillin, azithromycin and two isolates were resistant to cefotaxime. All tested isolates were sensitive to ciprofloxacin. Based on the antibiotic sensitivity test, most isolates were sensitive, but there were isolates resistant to antibiotics, especially amoxicillin and cefotaxime.
