Abstract
In this present study, the serotype of 40 Streptococcus suis isolates from submaxillary glands of pig carcasses sold in wet markets in Chiang Mai Province, northern Thailand, was investigated. Eleven serotypes, including types 2, 3, 4, 5, 7, 8, 9, 17, 21, 22 and 31, were found in the isolates by a Multiplex PCR combined with serum agglutination. Of the eleven serotypes present, type 3 was the most prevalent, while types 2, 4, 5 and 21 were of primary interest due to their human isolate serotype. The mrp+/epf - /sly - genotype was found to be the most prevalent genotype. This study indicates the importance of effective control of human S. suis infection due to raw pork or pig carcass handling in northern Thailand.
摘要
在本研究中，对泰国北部清迈府湿货市场销售的猪胴体颌下腺中分离出的40株猪链球菌血清型进行了调查。通过多重聚合酶链反应（Multiplex PCR）结合血清凝集试验，在分离株中发现了11种血清型，包括2型、3型、4型、5型、7型、8型、9型、17型、21型、22型和31型。在所发现的11种血清型中，3型最为常见，而2型、4型、5型和21型因其与人类分离株血清型相关而备受关注。发现mrp+/epf - /sly - 基因型是最常见的基因型。本研究表明，在泰国北部，有效控制因处理生猪肉或猪胴体而导致的人类猪链球菌感染具有重要意义。
