目的了解急性呼吸道感染儿童流感嗜血杆菌 ( HI)感染状况。方法对急性呼吸道感染儿童 113例及健康儿童 2 19例咽拭标本进行培养鉴定、生物分型及药敏试验。结果急性呼吸道感染儿童 HI分离率 ( 5 1.33% )显著高于健康儿童 ( P<0 .0 1) ,且两者均以生物型 型和 型占优势 ,但急性呼吸道感染儿童 HI生物 型明显高于健康儿童 ( P<0 .0 5 ) ;同时急性呼吸道感染儿童对常用抗生素的耐药率均较健康儿童偏高。结论 HI与呼吸道继发感染关系密切 ,且生物型 型起着重要作用 ;HI感染与其耐药性有一定关系
Objective To understand the status of Haemophilus influenzae (HI) infection in children with acute respiratory tract infection. Methods Thirteen children with acute respiratory tract infection and 29 children with throat swabs were enrolled in this study. Results The HI isolation rate of children with acute respiratory tract infection was significantly higher than that of healthy children (5 1.33%) (P <0.01), and both of them were predominantly biotype and type, but the HI biotype of children with acute respiratory infection was significantly higher In healthy children (P <0. 05); the same time, children with acute respiratory tract infection rate of commonly used antibiotics are higher than healthy children. Conclusion HI is closely related to the secondary respiratory tract infection, and the biotype plays an important role. HI infection has some relationship with its drug resistance
