Primary and secondary school children in Ryukyu Islands were subjected to throat culture for hemolytic streptococci (HS) to study the incidence of HS as a whole, group and type distribution, and the prevalence of rheumatic heart disease. The results were compared with those obtained in school children in Fuchu City of Tokyo Metropolis by the similar procedure.
The incidence of HS as a whole was much higher in Hateruma, Ishigaki and Koza of Ryukyu Islands than in Fuchu City. In typing of group A streptococci by T-agglutination it was interesting to see that the dominant type in Hateruma and Ishigaki was T-11, while in Koza it was T-12, which was similar to the dominat type in Tokyo and other part of Japan. The incidence of rheumatic heart disease in Koza, Ryukyu, was 10 times as high as Fuchu, Tokyo Metropolis, as expected. The discrepancy of types of streptococci in Ryukyu Islands is worth mentioning, and further investigation is continued by us.
