Backgrounds:
@EN The carrier rates of beta-hemolytic streptococci (BHS) and Streptococcus pyogenes of the children in Seoul were investigated epidemiologically and compared with those of Kangwon and Chungnam Province previously reported.
@ES Methods:
@EN Throat cultures were taken from the healthy 590 elementary school children who had no symptoms or signs of upper respiratory tract infection, and the beta-hemolytic colonies were identified with bacitracin disk and latex agglutination test.
@ES Results:
@EN Of those chidren, 103 (17.5%) yielded BHS and 76 (12.9%) did S. pyogenes. Eighteen strains (6.0%) of BHS were identified as group G, 4 ones (1.3%) as group C, 2 ones (0.8%) as group B, and the other three (1.0%) were classified as non-group
A,B,C,G.
@ES Conclusion:
@EN Including the results of Kangwon and Chungnam Province, BHS from the throats of healthy elementary school children in winter were similarly isolated from about 15% and S. pyogenes from about 10% respectively regardless of geographical
differences.
