母猪上呼吸道感染金黄色葡萄球菌的分离鉴定
Journal of Animal Science and Veterinary Medicine（2021）
Abstract
从内蒙古呼和浩特市郊区某猪场饲养的母猪鼻腔分泌物中分离到1株病原细菌.经细菌纯化培养和生化鉴定后,结果表明该细菌为革兰氏阳性.菌体形态为成对、短链状、葡萄串状排列的球菌.进一步进行了PCR扩增产物测序分析发现该菌株与金黄色葡萄球菌的同源性达99％.药敏试验显示,该菌株对拜有利高度敏感,对庆大霉素、头孢噻污、氧氟沙星、卡那霉素、氯霉素中度敏感,对林可霉素、四环素等耐药.结果显示,该分离菌符合金黄色葡萄球菌的生物学及分子学特性.
