反复呼吸道感染患儿的微生态研究

Microecological Study on Children with Recurrent Respiratory Infections

反复呼吸道感染（ＲＲＩ）在幼儿中较为常见。本文对４０例ＲＲＩ患儿口咽部菌群进行了定性、定量、定位检测。结果表明，需氧菌细菌群密度为２．１６３５±０．５０４７。３２例分离出两种以上需氧菌、以奈瑟氏菌和肺炎链球菌为多见，共检出９种需氧菌，７０株，６种厌氧菌，３９株。药敏试验表明，几种致病菌对青霉素等抗生素较敏感，而对红霉素、庆大霉素敏感率较低。

children with recurrent respiratory infection(RRI)were examined for theoral flora by qualitative,quantitative and locational analysis. The results showed that thedensity of aerobes was 2.1635±0.5047.More than two kinds of aerobes were isolatedin 32 cases and Neisseria and strep。 Pneumoniae were the most common. The testedbacterla were composed of 9 kinds and 70 strains of aerobes and 6 kinds and 39 strainsof anaerobes。 Drug sensitive test revealed that some pathogenic bacteria wre sensitive topenicillin but insensitive to erythromycin and gentamycin.
