慢性咽炎患者咽部细菌调查分析

Microbiological Analysis of Bacterial Population of Patients with Chronic Pharyngitis

目的分析慢性咽炎患者咽部细菌学特征。方法对136例慢性咽炎患者的咽分泌物进行细菌培养、分离和鉴定。结果共检测出细菌385株,分布最多的为α-溶血性链球菌、副流感嗜血菌和卡他莫拉菌,构成比分别为18.44%、9.87%和9.09%;病原菌315株,占81.82%;3种咽炎病类型中检测到最多的均是α-溶血性链球菌。结论咽部菌群紊乱是慢性咽炎病发作的主要原因,治疗前应进行细菌学检查,避免因滥用抗菌药物造成无效或菌群失调。

OBJECTIVE To analyze the bacteriological characteristics of chronic pharyngitis.METHODS Retropharyngeal abscess taken from 136 patients with chronic pharyngitis were cultivated for bacterial culture and identification.RESULTS A total of 385 strains were isolated.3 dominant bacterial species identified were α-Hemolytic Streptococcus accounting for 18.44%,Haemophilus parainfluenzae accounting for 9.87%,and Moraxella catarrhalis accounting for 9.09%.315 pathogeus of bacteria were isolated,accounted for 81.82% were isolated with the major 3.α-Hemolytic Streptococcus was the major pathogenic bacteria detected from all the 3 types of chronic pharyngitis.CONCLUSION Pharyngeal flora disturbance is the main reason for the disease of chronic pharyngitis,and bacteriological examination should be carried out before treatment to avoid the invalidation or flora disturbance caused by misuse of antibiotics.
