The epidemiological studies of S. suis infections in Japan were carried out between 1987 to 1991. A total of 380 S. suis strains isolated from pigs, cattle and a horse were serotyped by using antisera against S. suis types 1 to 22. A total of 318 (83.7%) of S. suis isolates were serologically typable. Serotype 2 was the most prevalent with 28.2%, followed by type 7 (10.8%), 1/2 (8.4%), 3 (7.4%) and 4 (5.5%). Of twenty S. suis strains isolated from cattle, eight were type 9, one was type 10, five were type 18, one was type 20 and five were untypable. One out of all the strains was also isolated from a racing horse with pneumonia. The majority of the isolates were originated from meningitis (38.2%), followed by from pneumonia (33.4%) and endocarditis (9.2%). Of all of the S. suis isolates, 333 isolates (87.6%) were identified correctly by API STREP 20 system.
1987年至1991年间在日本开展了猪链球菌感染的流行病学研究。使用针对猪链球菌1型至22型的抗血清，对从猪、牛和一匹马身上分离出的总共380株猪链球菌菌株进行了血清分型。总共318株（83.7%）猪链球菌分离株可通过血清学方法分型。2型最为常见，占28.2%，其次是7型（10.8%）、1/2型（8.4%）、3型（7.4%）和4型（5.5%）。从牛身上分离出的20株猪链球菌菌株中，8株为9型，1株为10型，5株为18型，1株为20型，5株无法分型。所有菌株中有1株还从一匹患有肺炎的赛马身上分离得到。大多数分离株源自脑膜炎（38.2%），其次是肺炎（33.4%）和心内膜炎（9.2%）。在所有猪链球菌分离株中，333株（87.6%）通过API STREP 20系统得到了正确鉴定。
