山羊皮下脓肿菌群结构分析及耳葡萄球菌的分离鉴定

Structure analysis of goat subcutaneous abscess bacterial flora and isolation and identification of Staphylococcus auricularis

  • 摘要: 河南省信阳山区某农户饲养山羊230只左右,其中约170只山羊相继在胸部、颈部、肩部、乳房等周围皮下发生脓肿,严重影响了山羊的生长发育和增重,给农户造成了严重的经济损失。为了了解该羊场山羊皮下脓肿菌群结构并指导临床合理用药,试验采用变性梯度凝胶电泳(DGGE)技术分析了山羊皮下脓肿内容物的菌群结构,并对脓肿内容物进行了细菌分离鉴定和药敏试验。结果表明:山羊皮下脓肿内容物的菌群结构相同,均为3种细菌,分别为葡萄球菌属(Staphylococcus sp.)、脱硫弧菌属(Desulfovibrio sp.)、丙酸杆菌属(Propionibacterium sp.)细菌;皮下脓肿内容物分离培养得到的细菌鉴定为具有β溶血环的凝固酶阴性耳葡萄球菌,该菌对庆大霉素、环丙沙星、红霉素等多种抗生素敏感。说明耳葡萄球菌是导致山羊皮下脓肿的主要病原菌之一,该菌对多种抗生素表现敏感。

     

    Abstract: A farmer in the Xinyang mountainous area of Henan Province raised about 230 goats; among them, about 170 goats developed abscesses under the skin around the chest, neck, shoulders, breasts, etc.,which seriously affected the growth and weight gain of the goats and caused serious economic losses to farmers. In order to understand the structure of the goat subcutaneous abscess bacterial flora of the farm and to guide the clinical rational use of drugs, the experiment used denaturing gradient gel electrophoresis(DGGE) technology to analyze the bacterial flora structure of the goat subcutaneous abscess content, and carried out bacterial isolation, identification and drug sensitivity test on the abscess content. The results showed that the structure of the bacterial flora of the abscess content under the goat skin was the same, all of which were 3 types of bacteria namely Staphylococcus sp.,Desulfovibrio sp.,and Propionibacterium sp.. The bacteria isolated and cultured from the contents of the subcutaneous abscess were identified as coagulase-negative Staphylococcus auricularis with β hemolytic loop, which was sensitive to gentamicin, ciprofloxacin, erythromycin and other antibiotics. The results suggested that Staphylococcus auricularis was one of the main pathogenic bacteria that caused abscesses under the skin of goats, and it was sensitive to a variety of antibiotics.
