| 摘 要： | 对１９９８年江苏分离的３株猪源链球菌进行了鉴定，其形态、染色均符合链球菌的特点，具α或β溶血，生化试验结果不稳定。用国际通用的链球菌乳胶分型诊断液检测上述分离株，均不在其检测范围，即不属于链球菌兰氏分群的Ａ～Ｇ群。但它们凝集猪链球菌２型抗血清，人工接种兔有致病性。表明此次流行的猪败血症的病原不同于以往的Ｃ群链球菌，不是马腺疫链球菌兽疫亚种，而是属于Ｒ群的猪链球菌２型。

| Abstract: | Three isolates were obtained from diseased pigs with septicemia in Jiangsu Province in summer 1998.The morphological,cultural and biochemistry characters indicated that the isolated bacteria belonged to genus Streptococcus.In addition,the API20 Strep system was reconfirmed the above result.Furthermore,the isolates could be agglutinated by the antiserum of Strep.suis type 2,but not by the Lancefild group AG latex diagnostic kit.The isolates demonstrated pathogenecity to rabbit but not to mouse.It concluded that Strep.suis type 2 was the pathogen of the pig disease occurred in Jiangsu during 1998. |
