对从 210 只狗的化脓性皮肤损伤中获取的样本进行了葡萄球菌培养检查。使用商业葡萄球菌鉴定系统中包含的生化测试，对总共 215 个葡萄球菌分离株进行了生物分型。在 201 株凝固酶阳性分离株中，197 株被鉴定为中间葡萄球菌，3 株为金黄色葡萄球菌，1 株为猪葡萄球菌。在 14 株凝固酶阴性分离株中，5 株被鉴定为表皮沙门氏菌，5 株为木糖沙门氏菌，3 株为模拟沙门氏菌，1 株为人沙门氏菌。使用标准纸片扩散法对所有葡萄球菌分离株进行抗菌药物敏感性测试。中间葡萄球菌分离株对头孢噻吩、甲氧西林和庆大霉素敏感。对氨苄青霉素、青霉素 G 和四环素的耐药性很常见。抗生素耐药性与皮肤感染的深度无关。对氨苄西林、青霉素、四环素和甲氧苄氨嘧啶-磺胺甲恶唑的耐药性与之前使用抗生素无关。对氯霉素、克林霉素和红霉素的耐药性增加与之前的抗生素治疗有关。已报告了分离的其他葡萄球菌物种的抗菌敏感性，但这些物种的数量较少，无法与中间葡萄球菌进行有意义的比较。
Specimens obtained from pyogenic skin lesions of 210 dogs were culturally examined for staphylococci. A total of 215 isolates of staphylococci were biotyped, using the biochemical tests contained in a commercial staphylococcal identification system. Of 201 coagulase-positive isolates, 197 were identified as Staphylococcus intermedius, 3 as S aureus, and 1 as S hyicus. Of 14 coagulase-negative isolates, 5 were identified as S epidermidis, 5 as S xylosus, 3 as S simulans, and 1 as S hominis. Antimicrobial susceptibility tests were done on all staphylococcal isolates, using the standard disk-diffusion method. Staphylococcus intermedius isolates were susceptible to cephalothin, methicillin, and gentamicin. Resistance to ampicillin, penicillin G, and tetracycline was frequent. Antibiotic resistance was not associated with the depth of skin infection. Resistance to ampicillin, penicillin, tetracycline, and trimethoprim-sulfamethoxazole was not associated with previous antibiotic use. Increased resistance to chloramphenicol, clindamycin, and erythromycin was associated with previous antibiotic therapy. Antimicrobial susceptibilities of the other Staphylococcus species isolated are reported, but the small numbers of these species precluded making meaningful comparison with S intermedius.
