空气中溶血性链球菌含量和流感流行关系

The Relationship between Hemolytic Streptococcus Density in Indoor Air and Influenza Epidemic

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，HS≤36cfu/m³有可操作性和实用性。

Abstract: The present study had shown that the detection rate sof Hemoly ticstreptoc occus in indoor air in public places were increased form 44. 2% during non-epidemic period of influen zato 77. 8% during influenza epidemic period, and the detection points of Hemolytic streptoc occus> 36cfu /m³ were in creased 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 Hemolyticstrep tococcus. Though the above results were obvious, the bacteria totals in those places were below its standard.The results of ours showed that Hemoly ticstrep tococcusisan indicator which can represent the population pollutionand the epidemic of respiratory system diseases, and the level of Hemolytics treptococcus no more than 36 cfu/m³ is practicableand applicable.
