ABSTRACT
We studied the factors influencing the colonization of Streptococcus in school age children aged 6-11 years from 2 low socioeconomic schools of the Bangkok Metropolitan area. 4,055 throat swab cultures were performed. Beta hemolytic Streptococcus (BHS) and beta hemolytic Streptococcus group A (BHSA) were isolated in 1,747 (43%) and 744 (18%) respectively. 1,547 questionnaires were returned from the children. Of these, 750 and 570 were found to have BHS and BHSA in the throat, respectively. Among the risk factors, considered, teeth brushing of one time or none per day was significant for BHS positive in the throat as compared with the BHS negative group, while personal hygiene such as sharing glass with other, playing in dirty water, poor housing sanitation and low family income was significantly associated with the BHSA positive group. With the combination of certain clinical manifestations, these factors may increase the accuracy of predicting streptococcal infection.

We studied the occurrence of Streptococcus group G in throat cultures obtained from school children of poor socioeconomic status and in sick children brought to our hospital. The results revealed a high occurrence of group G Streptococci (44% and 91.5% respectively) in cases positive for beta-hemolytic Streptococci.
