摘要:

猪链球菌(Streptococcus suis,SS)影响养猪业的重要病原菌之一。本文基于多酶恒温快速扩增(multienzyme isothermal rapid amplification,MIRA)技术建立快速检测SS及其血清2、7、9型3种主要临床血清型的新方法,该方法可在20~41 ℃温度下5~30 min内完成扩增,具有良好的特异性和敏感性;应用MIRA方法能够快速检测临床分离菌株中相应血清型,且与PCR方法的符合率为100%。上述结果表明,本研究所建立的MIRA方法可为临床诊断猪链球菌感染提供简便快捷的方法。

Abstract:

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.

Key words: Streptococcus suis, serovars, MIRA, rapid detection
