Abstract:This study aimed to obtain Streptococcus suis (S.suis) detection rate in healthy pigs and evaluate possibility of S.suis infection risk in China. A total of 337 throat swabs were collected from healthy pigs and enriched in selective culture medium. The S. suis specific 16S rRNA, gapdh, cps1j, cps2j, cps7h, cps9h, mrp, ef and sly genes were detected in DNA extracted from samples by polymerase chain reaction (PCR). showed that the detection rate of S.suis was the 93.8% (316/337). Within 316 positive samples, the detection rates of virulent genes were high and serotype 2 was the dominant serotype 61.4%(194/316). It’s suggested that the detection rate of highly virulent S.suis in healthy pigs was high. The possibility of S.suis infection risk in China cannot be ignored.
