Fourteen new capsular types of Streptococcus suis (types 9 to 22) are described. All reference strains are morphologically and biochemically similar to types previously described. Reference strain types 9 to 13, 15, 16, and 22 were isolated from diseased pigs, whereas types 17 to 19 and 21 came from clinically healthy pigs; type 14 was isolated from a human case of meningitis, and type 20 was isolated from a diseased calf. The group T streptococcus of de Moor has been included in the typing system as type 15. Two-way cross-reactions between types 6 and 16 and a one-way cross-reaction between types 2 and 22 have been demonstrated. In addition, several cross-reactions probably not due to capsular material were detected among different types by using the coagglutination test. This test should not be used alone; weak or multiple positive reactions must be confirmed by the capsular reaction test or the capillary precipitation test.
描述了14种猪链球菌的新荚膜型（9型至22型）。所有参考菌株在形态和生化方面均与先前描述的类型相似。参考菌株9型至13型、15型、16型和22型是从患病猪中分离出来的，而17型至19型和21型来自临床健康的猪；14型是从1例人类脑膜炎病例中分离出来的，20型是从患病小牛中分离出来的。德穆尔的T群链球菌已作为15型纳入分型系统。已证明6型和16型之间存在双向交叉反应，2型和22型之间存在单向交叉反应。此外，通过协同凝集试验在不同类型之间检测到了几种可能不是由荚膜物质引起的交叉反应。该试验不应单独使用；弱阳性或多重阳性反应必须通过荚膜反应试验或毛细管沉淀试验进行确认。
