急性喘息性支气管肺炎患儿病原学分析

Etiologic analysis of acute asthmatic bronchial pneumonia in children

目的探讨急性喘息性支气管肺炎患儿的病原学特点。方法选择急性喘息性支气管肺炎患儿95例,分别采集血、尿及痰标本,进行细菌培养、呼吸道病毒抗原检测、肺炎支原体(MP)培养及血清肺炎衣原体(CP)抗体IgM检测。分析阳性病例的临床资料。结果 95例中,检出1种或1种以上病原81例(85.3%)。其中,细菌、病毒、MP和CP检出率分别为27.3%、17.7%、48.3%和17.0%。细菌病原中以肺炎链球菌最多见,病毒中以呼吸道合胞病毒最常见。病原混合感染率为18.95%,以MP与细菌混合感染最常见。结论 MP是儿童急性喘息性支气管肺炎最常见的病原,也是混合感染的常见病原。

Objective To investigate the etiology of acute asthmatic bronchial pneumonia in children.Methods The examinations were performed in 95children with acute asthmatic bronchial pneumonia,which included sputum bacterial culture,respiratory virus antigen detection,Mycoplasma pneumonia（MP）culture and Chlamydia pneumonia antibody test.The etiologic characteristics of positive cases were analyzed.Results The positive specimens of one or more pathogens detected were 81（85.3%）of 95cases.Bacterial detection rate was 27.3%.Virus detection rate was 17.7%.Mycoplasma pneumonia detection rate was 48.3%.Chlamydia pneumonia detection rate was 17.0%.Streptococcus pneumoniae was the most common in bacteria.Syncytial virus was the most common in virus.Pathogen mixed infection rate was 18.95%.MP mixed with bacteria infection was the most common.Conclusion MP is the most common pathogen of acute asthmatic bronchial pneumonia in children,which is also the most common pathogen in mixed infections.
