1株猪源性链球菌的分离鉴定及药敏试验

Isolation and identification of a strain of Streptococcus suis and its drug sensitivity test

摘要

摘要:
目的报告2005年春季吉林省某猪场Ⅱ型猪链球菌感染猪群的徽生钧学检查和药物敏感试验结果。
方法从病、死猪中分离猪链球菌疑似菌株, 采用革兰染色镜检、生化反应和特异性诊断血清玻片凝集等方法, 鉴定菌株并进行药物敏感试验。
结果分离的疑似菌株经鉴定为Ⅱ型猪链球菌; 分离株对氨苄西林、利福平、万古霉素、头孢拉定、罗红霉素等5种抗生素敏感, 对庆大霉素等6种抗生素耐药。
结论采取饲养环境和饲料消毒、发病猪隔离、氨苄西林和利福平配合治疗等措施, 有效地控制了疫情, 未发生人的感染。

Abstract:
Objective To report the results of microbiological examinat ion and drug sensitivity test of Streptococcus suis type Ⅱ fulminant infection in swine in Jilin province in spring of 2005.
Methods Fromill or dead pigs, suspicious strains of Streptococcus suis were isolated.These strains were identified as Streptococcus suis type Ⅱbated on the results of Gram staining and microscopy, and slide agglutination test with specific diagnostic antiserum.
Results The isotates of Streptococus suis type Ⅱ were sensitive to five of the tested antibiotics such as Ampicillin and were resistant to six of the tested antibiotics such as gentamycin.
Conclusion By disinfection of breeding environment and feed, iso lation of the ill pigs, Ampicillin and Rifampicin used as their apeutic drugs, the fulminant epidemic of Streptococcus suis type Ⅱ was successfully controlled and non of the persons was infected with the microbe.
