小儿肺炎无荚膜流感嗜血杆菌和卡他布兰汉球菌的检测及分析

A study on non capsulated haemophilus influenzae and branhamella catarrhalis in children with pneumonia

目的 了解无荚膜流感嗜血杆菌 (NHi)和卡他布兰汉球菌 (B Cat)在小儿肺炎感染中的地位。方法 采用酶免疫分析法 (EIA) ,以 10株无荚膜的流感嗜血杆菌和 10株卡他布兰汉球菌为抗原 ,对 5 3例肺炎患儿的双份血清中无荚膜流感嗜血杆菌抗体 (NHi-Ab)和卡他布兰汉球菌抗体 (B Cat -Ab)进行检测。结果 有 2例NHi-Ab和 5例B .Cat-Ab阳性 ,分别占 5 3例肺炎患儿的 3 78%和 9 43% ;占其中 32例细菌性肺炎患儿的 6 2 5 %和 15 6 3%。结论 NHi和B .Cat感染在小儿肺炎中不可忽视。

Objective To study the role of Non capsulsted haemophilus influenzae(NHi)and Branhamella catarrhalis(B.Car) in children with pneumonia.Methods The Enzyme immunoassay(ELISA)was used to detect NHi antibody (NHi-Ab)and B.Cat antibody (B.Cat-Ab)from paired sera of inpatients with pneumonia.Blood cultures were done in these cases by standard methods.Results NHi and B.Cat infection was fonnd in 2(3.78%)and 5(9.43%)cases of pneumonia children respectively.And both HNi and B.cat were coinfected with other becteria in these patients.Conclusion NHi and B.Cat are the common pathogens of childhood pneumonia.
