This study determined the diversity of species and antimicrobial resistance of staphylococci isolated from dogs with a presumptive diagnosis of urinary tract infection (UTI). Urine samples from 348 dogs with clinical signs of UTI, according to clinical examination and urinalysis, were processed for isolation of Staphylococcus. Colonies in pure culture were identified by biochemical reactions and tested for susceptibility to 15 antimicrobials. Seventy isolates of staphylococci were obtained (20.1%). Staphylococcus pseudintermedius was the most frequent species (32.8%), followed by S. epidermidis (18.6%), S. simulans (15.7%), S. schleiferi schleiferi (11.4%), S. aureus (11.4%), S. schleiferi coagulans (7.2%) and S. saprophyticus (2.9%). All the isolates were resistant to at least 1 drug and 77.1% were multiresistant. The study reports the alarming antimicrobial resistance of members of the Staphylococcus genus isolated from canine UTI and highlights the importance of coagulase-negative staphylococci in its etiology.
本研究确定了从疑似患有尿路感染（UTI）的犬只中分离出的葡萄球菌的物种多样性和抗菌药物耐药性。根据临床检查和尿液分析，对348只具有UTI临床症状的犬只的尿液样本进行处理，以分离葡萄球菌。通过生化反应鉴定纯培养物中的菌落，并测试其对15种抗菌药物的敏感性。共获得70株葡萄球菌分离株（20.1%）。中间型假葡萄球菌是最常见的物种（32.8%），其次是表皮葡萄球菌（18.6%）、模仿葡萄球菌（15.7%）、施氏葡萄球菌施氏亚种（11.4%）、金黄色葡萄球菌（11.4%）、施氏葡萄球菌凝聚亚种（7.2%）和腐生葡萄球菌（2.9%）。所有分离株均对至少1种药物耐药，77.1%为多重耐药。该研究报告了从犬UTI中分离出的葡萄球菌属成员令人担忧的抗菌药物耐药性，并强调了凝固酶阴性葡萄球菌在其病因学中的重要性。
