摘要
目的 探讨江苏省南通、如皋、海安、泰兴等地爆发流行猪传染病的病因 ,控制疾病流行及采取预防对策。方法 我们对分离株进行全面研究 ,并比较了不同地点、不同来源的 3个分离株的生化特性、全菌体蛋白聚丙烯酰胺凝胶电泳图谱和DNA指纹图谱。结果 分离株均为革兰阳性菌 ,3个分离株具有相同的蛋白组成和DNA指纹图谱 ,属同一克隆株 ,但分离株与标准参照株不相同。结论 经综合分析鉴定 ,病原体为猪链球菌Ⅱ型 。
Objective In the summer of 1998, a pig infection disease outbroke in Jiangsu province of China. Many pigs and some men died. This study is to illuminate the cause, control and prevention of the disease. Methods The present research compared the biochemical characters of 3 isolated strains through protein fingerprint by PAGE and DNA fingerprint.Results The results showed that 3 isolated strains belonged to one colonal strain and came from the same original strain with same protein compound and DNA fingerprint. However, the 3 isolated strains were different from standard control strains. Conclusion It asserted the conclusion of epidemic investigation that the epidemic disease caused by diseased pigs and pathogen was transmitted to men from pigs. The pathogen was streptococcus suis Ⅱ.
