摘　　要：猪链球菌广泛存在于自然界,可引起猪链球菌病,以发烧、败血症、脑膜炎、肺炎、关节炎等为主要特征;猪链球菌病是一种重要的人畜共患传染病,共有35种血清型,其中以2型流行最广,危害最大。荚膜多糖抗原作为链球菌重要毒力因子,在引起猪链球菌病的过程中起到了关键性的作用,以此作为目的基因的PCR检测方法的报道也不在少数,现就近年来国内外猪链球菌2型荚膜多糖抗原基因(CPS2J)PCR检测技术进行综合论述,以期为实验室检测人员提供有关的资料。Streptococcus suis, which widely exists in natural environment, is an important medical pathogenic bacterium of swine streptococosis that causes symptoms of fever, septicemia meningitis, pneumonia and arthritis etc. Streptococosis is an important zoonosis which has severely harmed the swine industry since, it was found. There are 35 serotypes and type 2 is the most severe one. As one of the most important virulence factors of S, suis type 2,capsular polysaccharide（cps） plays an essential role in leading to streptococosis. Also there are many reports of detecting＇S, suis type 2 by PCR assays targeting at this gene. A cornprehensive introduction of this gene by PCR both at in the hope of providing some beneficial information home and abroad recently was reviewed in this article for others.
