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 Mycoplasma pneumoniae (MP) in children in Zhanjiang area. Methods: Serum MP antibody was detected in children with pneumonia who were treated in our hospital from January 2005 to December 2008 by SERAPI-A-MYCOII, , Different seasons, different age and gender of MP pneumonia incidence statistics. Results: The number of subjects was 2825 and the positive rate of MP antibody was 40.2%. The positive rate of the number of different age groups, different genders have significant differences. The prevalence of MP infection in infants aged 0 ~ 1 years was 9.5%. The incidence of MP infection in infants aged 1 ~ 3 years was 40.4%. The incidence of MP infection in pre-school children aged 4 ~ 6 years was 45.4%. The prevalence of MP infection in 7 ~ 14 school years was 48.3% %. The positive rate of MP in 0-1 year old group was significantly lower than that in other age groups (x2 = 110.5523, P <0.01). The positive rates of pneumonia in boys and girls were 36% and 49.4%, respectively, with significant difference (x2 = 44.9891, P <0.01). Disease can occur throughout the year. Conclusion The incidence of MP pneumonia is closely related to age, gender, season and year.
