流感流行期社区门诊部细菌含量变化

THE CHANGE OF THE BACTERIA IN FLU EPIDEMIC AT CLINIC REGION.

目的:观察流感流行期与非流行期空气细菌总数(BT)与溶血性链球菌(HS)在社区门诊部的变化。方法:用撞击法测定细菌总数(BT)和溶血性链球菌(HS)。结果:HS检出率由非流行期的2 8. 1 %增至流行期的73 . 3 %(P <0 . 0 1 ) ,HS >3 6cfu/m3,由1 3. 3 %增至4 4 . 0 % ,而BT均未见超标。结论:定量测定社区门诊部的HS ,可作为直接反映呼吸系统传染病流行的灵敏指标;

Objective:To observe the change of the flu BT and HS in the epidemic or non-epidemic period.Method:The BT and HS were measured in dashing.Result:We found that the HS has increased from 28.1% in epidemic to 73.3% in non-epidemic(P<0.01),HS>36 cfu/m 3,increasing from 13.3% to 44.0%.But the BT did not excess the standard.Conclusion:Observing the HS in clinic region,we can get the epidemic sensitive index directly of the respiratory infectious disease which can easily disseminate in clinic region in the airtight.
