An epidemiological survey of group A, B, C & G hemolytic streptococci isolated from the Throat of Diabetic Children Streptococcicosis Study Group

Abstract

The incidence of group A, B, C & G hemolytic streptococci residing in the throat of children with diabetes was surveyed. The survey was carried out in August, 1982 and August, 1983. Included in the surveys were 136 diabetic children. The survey was also carried out with healthy school children at the same term as the contrast. The detection rate of the streptococci among the diabetic children was significantly higher than the healthy school children. A great portion of streptococci detected from these diabetic children was classified into group B, on the other hand, from the healthy school children, group A. Although from healthy school children, BIII, BIa and several other types were isolated, from diabetic children only BIa and BIII were isolated. The detection rate of the streptococci among the diabetic children was significantly higher in the early days in camp for improvement of diabetes than in the last day. In the latter case the detection rate was similar to that among healthy children. In the other words following antidiabetic therapy as diabetes improved the detection rate were also improved. Among these 136 diabetic children examined 31 gave positive cultures at both surveys each year. Serogroups or serotypes in each year examinations, isolates, were identical in 26 cases. Most of these groups were group B and the types were Ia and III.
