Simultaneous detection of 33 Streptococcus suis serotypes using the luminex xTAG® assay™
2015
Abstract We report the development and evaluation of a serotype-specific xTAG luminex assay (SSA) that allows detection of the 33 serotypes of Streptococcus suis ( S. suis ). This assay is based on wzy gene targets directly involved in the cps biosynthesis and can be completed 40 min post-PCR amplification. The assay correctly and specifically identified the serotype of all 209 isolates tested, in comparison with two serotyping multiplex PCR methods previously developed. The sensitivity was higher than that of the previously described methods. The SSA system described here provides an easy-to-use, high-throughput system for rapid detection of S. suis serotypes.
