摘　　要：通过流感流行期观察公共场所空气中溶血性链球菌（ＨＳ）含量发现：ＨＳ检出率由非流行期的４４．２％增至７７．８％（Ｐ＜０．０５），ＨＳ＞３６ｃｆｕ／ｍ３由７．９％增至４４．２％（Ｐ＜０．０１），ＨＳ＞３６ｃｆｕ／ｍ３，最大倍数由２．２增至１１．１（Ｐ＜０．０１），以低档场所污染最严重。同时在血平皿上还发现有一种轻度溶血圈的脓绿色Ｇ氏阳性球菌落（７６．２％）。然而细菌总数（ＢＴ）无一例超标。提示：ＨＳ是一种直接反映在人群生理活动和呼吸系统传染病流行的灵敏指标。The present study had shown that the detection rates of Hemolytic streptococcus in indoor air in public places were increased form 44 2% during non epidemic period of influenza to 77 8% during influenza epidemic period,and the detection points of Hemolytic streptococcus >36cfu/m 3 were increased from 2.2 time to 11 1 times,especially the points of simly equipped places.In the meantime,some kind of gram positive bacteria with hemolytic rings was found in company with Hemolytic streptococcus.Though the above results were obvious ,the bacteria totals in those places were below its standard.The results of ours showed that Hemolytic streptococcus is an indicator which can represent the population pollution and the epidemic of respiratory system diseases,and the level of Hemolytic streptococcus no more than 36 cfu/m 3 is practicable and applicable.
