摘  要:
湖南省长沙市某黑豚养殖场发生疫情,通过对发病黑豚临床和病理学检查,从病料中分离到成链状的革兰氏阳性细菌,通过鲜血琼脂平板培养菌落具β溶血,PCR扩增和测序结果显示与C群兽疫链球菌有很高同源性,在小鼠致病性试验中,发病致死的小鼠组织内可再次分离到该菌。临床与实验室检测结果表明:该黑豚确系C群兽疫链球菌感染。

摘  要:
To diagnose the disease of guinea pig from a farm in Changsha Hunan province,one of the pathogenic bacteria had been isolated from died animal. According to clinical observation,laboratory detection and animal pathogenicity test,a case of Streptococcus equi subsp. Zooepidemicus infection was confirmed. The morphological observation showed that the bacteria was Gram-positive streptococcus and β hemolysis in blood agar culture,its 16 S rRNA gene shared highly homologous with Streptococcus equi subsp. zooepidemicus. The same bacteria could be isolated from mice challenged by the bacteria in the pathogenicity test.
