目的：对呼吸道感染患者进行肺炎支原体（M P ）‐Ig M 抗体检测，分析其年龄、季节、性别感染规律，为临床诊治提供依据。方法采用德国欧蒙公司（EUROIMMUN）MP‐IgM抗体诊断试剂盒对2014年1～12月送检的7098例呼吸道感染患者（来自山东省各市县医院）血清进行检测。结果在7098例患者中检出M P‐Ig M抗体阳性898例，阳性率为12．65％。各年龄组阳性率分别为婴儿期（＜1岁）15．24％、幼儿期（1～＜3岁）18．30％、学龄前期（3～＜6岁）24．21％、学龄期（6～＜15岁）25．44％、青年期（15～＜28岁）9．72％、成年期（28～60岁）4．60％、老年期（＞60岁）2．62％。每年不同季节均有患者感染M P ，其中秋冬季MP感染率高于夏季，以冬季感染率最高。结论呼吸道感染患者中MP感染率较高，儿童感染率明显高于成人，学龄期儿童为好发年龄，易发季节为秋冬季。对呼吸道感染患者应进行M P‐Ig M抗体测定，可为临床诊治提供依据。%Objective To analyze the IgM antibody of Mycoplasma pneumoniae in patients with respiratory tract infection ,and to provide evidence for clinical diagnosis and treatment by analyzing their age ,season ,and gender .Methods Detected the IgM antibod‐y of Mycoplasma pneumoniae in 7 098 patients with respiratory tract infection in the company from January 2014 to December 2014 .The test kits were from the EUROIMMUN company in German .The samples came from the hospitals in Shandong province . Results Among the 7 098 patients ,898 patients were positive for MP-IgM ,and the positive rate was 12 .65% .The positive rates of each age were as follows .Infants(0 -1 years old):15 .24% ;early childhood(1 -3 years old):18 .30% ;school age(3 -6 years old):24 .21% ;school age(6-15 years old):25 .44% ;youth(15-28 years old):9 .72% ;adult stage(28-60 years old):4 .60% ;old age(>60 years old):2 .62% .Patients infected with MP in different seasons ,and the infection rate was higher in autumn and winter than in summer ,and the infection rate was the highest in winter .Conclusion MP infection rate was higher in patients with respira‐tory tract infection ,and the infection rate of children was significantly higher than that of adults .The school age is a age group of high incidence of the disease .Autumn and winter are the season with high morbidity .MP-IgM antibody was measured in patients with respiratory tract infection ,which can provide the basis for clinical diagnosis and treatment .
