Evaluation of bacteria isolated from different animal species and antibiotic resistance in the veterinary diagnostic laboratory

Isolation of bacteria can be performed by taking correct and convenient samples, especially from the infection site. In addition, after isolation of the bacteria, the antimicrobial susceptibility test should be performed routinely to treat animals conveniently. For this purpose, 129 isolates were included in the current study from different animal origins and different examination materials in the culture collection of Atatürk University Faculty of Veterinary Medicine Department of Microbiology between 2020 and 2021. The isolates were identified by bacteriological methods and their antibiotic resistance was evaluated phenotypically. In the study, it was determined that bacteria belonging to the Staphylococcus genus (27.2%) were mostly involved in different infections. Overall results displayed those bacteria tested in this study were resistant to neomycin (100%), penicillin (76.74%), oxytetracycline (73.80%), and sulfamethoxazole-trimethoprim (61.25%) with a different rate, whereas they were susceptible to cephalosporin antibiotics (cefovecin %64.3 ceftiofur %80, and cefoxitin %81.8) used in the current study.
