目的分析十堰地区下呼吸道感染患儿肺炎支原体(MP)感染状况。方法对当地就诊的493例下呼吸道感染患儿采用间接免疫荧光法检测MP-Ig M,分析MP-lg M阳性率及其与性别、季节及年龄的关系。结果493例下呼吸道感染患儿的MP-Ig M阳性率为40.16%,其中男童为37.11%,女童为45.71%;性别间差异无统计学意义(P>0.05)。第四季度MP-Ig M阳性率为52.24%,分别高于其他3个季度(P<0.05)。MP-Ig M阳性率随年龄增长逐渐上升,7~14岁学龄儿童高达74.58%,明显高于其他年龄段(P<0.05)。结论十堰地区下呼吸道感染患儿MP阳性率较高,与季节、年龄的关系密切,应引起重视。
Objective To analyze the infection status of Mycoplasma pneumoniae (MP) in children with lower respiratory tract infection in Shiyan. Methods 493 cases of local lower respiratory tract infection in children with indirect immunofluorescence detection of MP-IgM, MP-lg M positive rate and its relationship with gender, season and age. Results The positive rate of MP-Ig M in 493 children with lower respiratory tract infection was 40.16%, of which 37.11% for boys and 45.71% for girls. There was no significant difference between the sexes (P> 0.05). The positive rate of MP-Ig M in the fourth quarter was 52.24%, higher than the other three quarters (P <0.05). The positive rate of MP-Ig M gradually increased with age, while the percentage of children aged 7 ~ 14 was 74.58%, significantly higher than that of other age groups (P <0.05). Conclusion The positive rate of MP in children with lower respiratory tract infection in Shiyan area is high, which is closely related to the season and age, and should be taken seriously.
