候诊室空气中溶血性链球菌含量与流感流行关系

THE RELATIONSHIP BETWEEN HEMOLYTICS STREPTOCOCCUS AND INFLUENEZ IN WAITING ROOM OF HOSPITAL

目的 :观察流感流行期与非流行期医院候诊室空气中溶血性链球菌 (HS)的变化。方法 :通过现场微生物采样与实验室培养 ,调查候诊室溶血性链球菌污染水平。结果 :HS检出率由非流行期的 2 3.3%增至 6 2 .5 % (P<0 .0 1) ,HS>36 cfu/ m3,由 11.3%增至 15 .9% ,在培养皿上发现一种轻度溶血圈的脓绿色 G氏阳性球菌落 (6 5 .4 % )。结论 :HS是一种直接反映在人群活动场所和呼吸系统传染病流行的灵敏指标。

Objective:To explore the changes of hemolytics streptococcus(HS) in epidemic and un-epidemic of influenza(Flu) in air of waiting room of hospital.Methods:HS level was investigated in waiting room by microorganism sampling and incubation.Results:Positive rate of HS was 62.5 percent( P <0.01) in influenza epidemic.Mildly Hemolysis ring of Gram's positive coccus bacteria was be observed in petridish,which positive rate was 65.4 percent.Conclusion:HS was a kind of sensitive index in public site for respiratory system infectious disease.
