目的：分析肺炎支原体（M P ）在儿童呼吸道疾病中的感染状况以及与患儿性别、年龄、季节和临床特征等的相关性。方法回顾性分析2013年1～12月因呼吸道感染住院的655例儿童的临床资料。结果 M P抗体检测阳性率为48．09％；女童多于男童，3岁以上儿童易感染，冬春季为MP感染高发季节；年龄越大，MP抗体阳性率越高，肺炎支原体肺炎（MPP）及大叶性肺炎的比例也越高，差异有统计学意义（P＜0．05）；年龄越小，白细胞计数越高，C反应蛋白（CRP）及中性粒细胞升高的比例也越高，差异有统计学意义（P＜0．05）。结论 MP是3岁以上儿童呼吸道感染中的常见病原菌，冬春季高发。感染MP后，年龄越大M P抗体阳性率越高，且易罹患肺炎；年龄越小，白细胞计数越高，CRP及中性粒细胞升高的比例也越高。

Objective To analyze the MP infection status in children with respiratory tract disease and the correlation with gen‐der ,age ,season and clinical conditions .Methods To investigate the clinical data retrospectively of 655 children with respiratory tract infection from January to December 2013 .Results The positive rate of MP antibody was 48 .09% with a higher incidence in girls than boys ,and those above 3 were more susceptible to it .Winter and spring were the peak seasons .The older group had a higher positive rate of MP antibody ,together with high morbidity of MPP and LP ,the differences were statistically significant (P<0 .05) ,while the younger group was inclined to get higher WBC count and percentage of increasing CRP and neutrophils ,the differ‐ences were statistically significant(P<0 .05) .Conclusion MP is a common pathogenic bacteria causes respiratory tract infection in children above 3 years ,especially in winter and spring .The antibody positive rate rise with age and the infected children are more likely to have pneumonia meanwhile the younger group has higher WBC count ,in which more cases get higher level of CRP and neutrophils .
