A total of 58 Streptococcus suis strains were isolated from deceased pigs submitted to the National Veterinary Institute, Regional Laboratory in Kuopio, Finland, over a 3 1/2 year period, most frequently from cases of pneumonia. The bacteria were isolated from cases of meningitis, sepsis, rhinitis, endocarditis and abortion. S. suis was also isolated from nasal cavity, lung and brain of some sick piglets without signs of inflammation. Further S. suis was detected in 12 out of 107 tonsils of healthy fatteners tested. S. suis strains were identified by biochemical methods followed by typing. The most common capsular types were 7, 3 and 2, respectively. Only one type 1 strain and no types 6 and 9 strains were found. All S. suis strains tested were sensitive to penicillin and ampicillin. S. suis is not uncommon in Finnish pig herds. S. suis may be regarded as a potentially pathogenic organism which under certain predisposing conditions may cause serious disease.
在三年半的时间里，芬兰国家兽医研究所库奥皮奥地区实验室从提交的病死猪中总共分离出58株猪链球菌，其中大部分来自肺炎病例。这些细菌还从脑膜炎、败血症、鼻炎、心内膜炎和流产病例中分离得到。猪链球菌也从一些没有炎症迹象的患病仔猪的鼻腔、肺部和大脑中分离得到。此外，在107头接受检测的健康育肥猪的扁桃体中，有12头检测出猪链球菌。猪链球菌菌株通过生化方法鉴定，随后进行分型。最常见的荚膜类型分别为7型、3型和2型。仅发现1株1型菌株，未发现6型和9型菌株。所有检测的猪链球菌菌株对青霉素和氨苄青霉素敏感。猪链球菌在芬兰猪群中并不罕见。猪链球菌可被视为一种潜在的致病生物，在某些诱发条件下可能导致严重疾病。
