Cat, dog, conjunctivitis, Staphylococcus spp., antimicrobial resistance


In this study, determination of presence of some bacteria causing conjunctivitis cases in cats and dogs and their susceptibility to various antimicrobial agents were aimed. For this purpose, the isolates obtained from ocular swab samples of cats and dogs diagnosed with conjunctivitis clinically, were identified by MALDI-TOF MS. The susceptibility to various antimicrobial agents of identified bacteria was determined by disk diffusion method. It was observed that the isolation rate of Gram positive bacteria from ocular swab samples was higher than Gram negative ones. It was determined that the mostly isolated bacteria species from the samples was Staphylococcus pseudintermedius.  Staphylococcus felis and Streptococcus canis that have zoonotic potential were isolated from 4 cases, separately. Generally, antimicrobial resistant rate was found to be low in isolated bacteria in the research. On the other hand, it was determined that imipenem and ampicillin resistance in Enterococcus spp. and extended spectrum beta lactam resistance in Enterobacteriaceae were high. In this study, it was concluded that Staphylococcus spp. were among the primer agents of conjunctivitis cases in cats and dogs. With the data obtained from the study, it was concluded that treatment with gentamicin, cephalosporin, enrofloxacin, clindamycin, ciprofloxacin, chloramphenicol could be effective in cases of conjunctivitis caused by Gram positive bacteria while gentamicin, enrofloxacin, piperacillin+tazobactam, imipenem and erythromycin treatment could be effective in cases caused by Gram negative bacteria.
