儿童迁延性细菌性支气管炎病原学研究进展

Microbiology progress of protracted bacterial bronchitis in children

儿童迁延性细菌性支气管炎(PBB)是儿童慢性咳嗽的常见病因之一。PBB常见病原菌为流感嗜血杆菌、肺炎链球菌、卡他莫拉菌,病毒亦参与PBB的发生发展,也有多种病原混合感染的报道。此外,PBB的微生物组学与健康儿童不同,存在下呼吸道菌群紊乱。现就近年来有关PBB的病原学研究进展进行综述。

Protracted bacterial bronchitis(PBB)is one of the common causes of chronic cough in children.The common pathogenic bacteria of PBB include haemophilus influenzae,streptococcus pneumoniae and moraxella catabilis.Viruses are also involved in the development of PBB.In addition,the microbiome of PBB is different from that of normal children,with lower respiratory tract flora disorder.This paper summarized the recent progress in the microbiology of PBB.
