Streptococcus suis type 2 is a frequent cause of diseases in pigs and humans worldwide including Diseased pigs are the cause of the spreading of the disease in food especially fresh pig blood raw or undercooked pork as well as causing infection through human contact to raw meat. In Thailand a lack of studies concerning epidemiological serotyping and genotyping in pigs and human isolates in the same time period was reported. So our study collected data from both pig and human infection during 2007 and 2010. Objective of the study is to know the serotype or genotype of diseased strains from pigs and human being. Design. Our groups gathered data by collecting of eleven diseased pig isolates from the Veterinary research and development center uppermost Northeast region and human isolates from the hospital of uppermost Northeast and North of Thailand then isolated and identified by performing biochemical test serotyping and PCR method. Results. This study found that three of S. suis serotype 2 three of serotype 9 and the less non-typical in diseased pigs from uppermost Northeast region. It showed that serotype 2 was present in all human isolates from Khon Kaen Northeast region Lumpoon and Chiang Mai in the North region of Thailand. Conclusion. Many serotypes of S. suis caused animal infection. S. suis capsular type 2 represented at least one-third of all cases isolated from diseased pigs which was also shown in our study and many previous studies. In many previous studies most S. suis serotype 2 is a causative agent of human diseased our study showed that all cases are also S. suis serotype 2 in North region found most S. suis serotype 2 and some serotype .
