猫源性人葡萄球菌的分离与鉴定
摘要
为诊断扬州大学动物医院接诊的一例患泌尿系统感染猫的致病原因,无菌采集了该患猫的尿液进行尿液培养、革兰染色镜检、生化试验、MALDI biotyper(全自动快速生物质谱检测系统,MBT)分析对分离菌进行鉴定;小鼠攻毒试验确定分离菌的毒性,药敏试验分析其对抗生素药物的敏感特性。结果显示,该细菌为革兰阳性球菌,可发酵果糖、蔗糖等。MBT分析结果,该菌为人葡萄球菌。小鼠攻毒试验及回归试验显示该菌有较强毒性,可致小鼠死亡。药敏试验结果显示,该菌对新霉素、卡那霉素、丁胺卡那霉素、美洛西林、庆大霉素等抗生素均极为敏感。以上结果表明,该猫患泌尿系统感染的致病菌为人葡萄球菌,选用药敏试验结果提示的药物后,该猫的疾病得到治愈。
