Abstract

Sequential multiplex PCR was evaluated for detection of multiple serotypes directly from nasopharyngeal secretions. A total of 279 nasopharyngeal swab samples were tested blindly. When limited to the 29 serotypes identifiable by the molecular method, the mean number of serotypes identified by the conventional latex/Quellung method was 0.85, which was significantly lower than that by the molecular method ( <0.0001). The multiplex PCR method identified significantly more serotypes than the latex/Quellung method if limited to the 29 serotypes (=0.001 and =0.014, respectively).
