Fig. 4From: DNA-based culture-independent analysis detects the presence of group a streptococcus in throat samples from healthy adults in JapanGAS detection from throat swab samples of healthy adults. a By the culture-dependent method, GAS was isolated from 5 of 148 swab samples. b By the culture-independent method, the presence of GAS DNA was PCR-confirmed for each sample by PCR with 16S rRNA and V-Na+-ATPase primers. emm sequence information was acquired from 25 samples. Additional emm type (detected in this study) information is shown in Additional file 1: Table S4Back to article page
