Antibiogram profiles were determined using the Kirby–Bauer disk diffusion method.
CC: clindamycin, 2 μg/disc; E: erythromycin, 15 μg/disc; FFC: florfenicol, 30 μg/disc; GM: gentamycin, 10 μg/disc; N: neomycin, 30 μg/disc; P: penicillin, 10 μg/disc; SD: sulfadiazine, 0.25 μg/disc; SPT: spectinomycin, 100 μg/disc; SXT: sulfamethoxazole/trimethoprim, 23.75/1.25 μg/disc 23.75/1.25 μg/disc; T: oxytetracycline, 30 μg/disc; TE: tetracycline, 30 μg/disc; XNL: ceftiofur, 30 μg/disc. S: sensitive, I: intermediate.
All three isolates were used in Experiment 1. SG1 was used in Experiment 2. Sensitivity based on recommendations determined by the American standard of the Clinical and Laboratory Standards Institute.
