The diversity of species of the genus Staphylococcus sp. and the antimicrobial resistance of isolates from 151 unmedicated dogs of both sexes with a clinical diagnosis of otitis were recorded. Ninety-one isolates of Staphylococcus spp. were identified by biochemical reactions and tested for susceptibility to 15 antimicrobials. Coagulase-positive species were most common; S. pseudintermedius (38.4%), S. schleiferi schleiferi (15.4%), S. aureus (14.3%), S. epidermidis (11%), S. simulans (11%), S. schleiferi coagulans (8.8%) and S. saprophyticus (1.1%). All the isolates showed resistance to at least one drug and 89% were multiresistant. Amoxicillin combined with clavulanic acid and oxacillin were the most effective, while resistance was widely observed for neomycin and erythromycin. The results highlight the recognition and the potential need for bacterial culture with species identification and antimicrobial susceptibility tests for appropriate antimicrobial therapy.
记录了151只临床诊断为中耳炎的未用药雌雄犬葡萄球菌属物种的多样性及分离株的抗菌耐药性。通过生化反应鉴定出91株葡萄球菌属菌株，并对其进行了15种抗菌药物的敏感性测试。凝固酶阳性菌株最为常见；假中间葡萄球菌（38.4%）、施氏葡萄球菌施氏亚种（15.4%）、金黄色葡萄球菌（14.3%）、表皮葡萄球菌（11%）、模仿葡萄球菌（11%）、施氏葡萄球菌凝聚亚种（8.8%）和腐生葡萄球菌（1.1%）。所有分离株均对至少一种药物耐药，89%为多重耐药。阿莫西林联合克拉维酸和苯唑西林最为有效，而新霉素和红霉素耐药情况普遍。结果强调了进行细菌培养及物种鉴定和抗菌药物敏感性测试以进行适当抗菌治疗的必要性。
