A study was made of patients investigated by general practitioners. Over a three-year period Streptococcus pyogenes (group A) was isolated most commonly from vaginal and vulval swabs collected in the winter. The serotypes of strains indicate that some had probably been derived from the skin and others from the respiratory tract. The two sources are thought to have masked a consistent, but not obvious, seasonal variation in streptococcal vulvo-vaginitis acquired usually from streptococcal infections of the respiratory tract in winter and from those of the skin in summer.
对全科医生所调查的患者进行了一项研究。在三年期间,化脓性链球菌(A组)最常从冬季采集的阴道和外阴拭子中分离出来。菌株的血清型表明,一些可能来自皮肤,另一些来自呼吸道。这两种来源被认为掩盖了通常由冬季呼吸道链球菌感染和夏季皮肤链球菌感染引起的链球菌性外阴阴道炎中一种持续但不明显的季节性变化。
