Streptococcus suis (SS) is one of the important pathogens causing serious economic losses in the pig farming industry. Here, we developed a novel rapid detection method for detecting SS and serovars 2, 7 and 9 based on multienzyme isothermal rapid amplification (MIRA) technology. The MIRA assays were validated for detection of SS and it serovars within 5 to 30 min at 20-41 ℃, with relative higher specificity and sensitivity. There are 100% agreement between our MIRA and PCR methods in the detection of clinical samples. Our results showed that the MIRA was a useful diagnostic method for rapid diagnosis of SS infection.
