A study was made of the level of carrier-state, serological characteristics, virulence and toxigenicity of beta-hemolytic streptococci isolated from children in two towns with a different incidence of scarlet fever located in the contrast climatic zones. It was found that the level of carrier-state of beta-hemolytic streptococci and biological properties of the circulating strains were important factors associated with the incidence of scarlet fever.
对从位于不同气候区、猩红热发病率不同的两个城镇的儿童中分离出的β-溶血性链球菌的带菌状态水平、血清学特征、毒力和产毒性进行了研究。结果发现，β-溶血性链球菌的带菌状态水平和流行菌株的生物学特性是与猩红热发病率相关的重要因素。
