湛江地区小儿肺炎支原体感染调查分析

An Investigation and Analysis of Mycoplasma Pneumonia in Pediatric Patients in Zhanjiang Area

目的:探讨湛江地区小儿肺炎支原体(MP)感染情况。方法:采用日本富士瑞必欧株式会社肺炎支原体抗体检测试剂(SERODI-A-MYCOII),对2005年1月至2008年12月在本院就诊的肺炎患儿进行血清MP抗体检测,对不同年度、不同季节、不同年龄及性别MP肺炎的发病情况进行统计。结果:受检人数2825例,MP抗体阳性率为40.2%。阳性率的多少与不同的年龄段、不同性别有明显区别。0～1岁婴儿期MP感染率为9.5%;1～3岁组幼儿MP感染率为40.4%;4～6岁学龄前期MP感染发病率为45.4%;7～14学龄期MP感染率为48.3%。0～1岁组MP阳性率明显低于其他年龄组,差异有统计学意义(x2=110.5523,P<0.01)。男、女性肺炎患儿阳性率分别为36%、49.4%,两者比较差异有统计学意义(x2=44.9891,P<0.01)。一年四季均可发病。结论MP肺炎的发病与年龄、性别、季节和年度有密切关系。

Objective：To investigate the infection of pediatric mycoplasma pneumonia in Zhanjiang area.Method：Children with pneumonia were detected by using MP antibody reagents provided by Fujirebio lnc from January 2005 to December 2008..And the incidences of mycoplasma pneumonia in different years,different seasons,different age and sex were analyzed.Results：A total of 2825 blood specimens were detected and the MP-positive rate was 40.2%.With differences existed between age groups and gender.Positive rates of different ages：9.5% in group of less 1 year old, 40.4% in group from 1 to 3 years old, 45.4% in group from 4 to 6 years old and 48.3% in group from 7 to 14 years old respectively.The differences of positive rate between different ages were significant （x2=110.5523, P0.01）.Positive rate （49.4%） of MP antibody in female was higher than that （36%） in male, and the difference between them was significant （x2=44.9891, P0.01）.Throughout the year will be the incidence.Conclusion：The incidence of MP was closely related to age, sex, season and year.
