Identification of Less-Common Streptococcus pneumoniae Serotypes by a Multiplex PCR-Based Reverse Line Blot Hybridization Assay

摘要

We developed a multiplex PCR-based reverse line blot (mPCR/RLB) assay to identify 50 uncommon pneumococcal serotypes. In combination with a previously described mPCR/RLB assay (3), all 90 pneumococcal serotypes can be identified individually (32 serotypes) or, because of predictable cross-reactions, to within small groups of two to five related serotypes (58 serotypes), which can be distinguished using serotype-specific antisera.
