DNA-based culture-independent analysis detects the presence of group a streptococcus in throat samples from healthy adults in Japan.

Our results suggest that culture-independent methods should be considered for profiling GAS in the healthy hosts, with a view to obtaining better understanding of these organisms. The GAS-specific primers (16S rRNA and V-Na+-ATPase) used in this study can be used to estimate the maximum potential GAS carriage in people.
