Two hundred and twenty four hospitalized children in Baghdad aged between 1 month and 10 years were examined for Streptococcal infections. Thirty-four percent of the throat and saliva specimens were positive for beta-hemolytic streptococci. Males were more susceptible to infection with group A streptococci than females. Streptococcus of group A was isolated from 39.5% of the positive cases while group G was 47.4%. The etiological significance of the latter group in tonsillitis and otitis media is to be further investigated. Ninety six percent of the isolated streptococci were T typable and 13.3% of the strains were M typable. A high frequency of type T-11 was found in streptococcal infections. T type 3875 was found to be a new provisional type. All isolates were M untypable, and antiopacity factor negative except for two isolates of T type 4 which were positive in both typings.
对巴格达224名年龄在1个月至10岁之间的住院儿童进行了链球菌感染检查。34%的咽喉和唾液标本β-溶血性链球菌呈阳性。男性比女性更容易感染A组链球菌。A组链球菌从39.5%的阳性病例中分离出来,而G组为47.4%。后一组在扁桃体炎和中耳炎中的病因学意义有待进一步研究。96%的分离链球菌可进行T分型,13.3%的菌株可进行M分型。在链球菌感染中发现T-11型的频率很高。发现3875型是一种新的暂定型。除两株T型4分离株在两种分型中均为阳性外,所有分离株均无法进行M分型且抗混浊因子呈阴性。
