目的:了解本地区肺炎支原体(MP)感染状况。方法:用被动凝集法检测呼吸道感染患者血清中肺炎支原体抗体(MP-Ab),并对6795例检测结果进行分析。结果:检测结果总阳性率为46.4%;男、女性患者阳性率分别为41.7%、51.9%,差异有统计学意义(P<0.05);各年龄组差异有统计学意义(P<0.05),8岁～14岁阳性率最高;季节发病率差异有统计学意义,秋季阳性率最高。结论:本地区MP感染率较高;3岁～14岁儿童为高危人群;女性感染机会高于男性;秋冬季高发;被动凝集法可作为支原体肺炎实验室诊断的常规检测方法。
Objective: To understand the status of Mycoplasma pneumoniae (MP) infection in this area. Methods: Serum Mycoplasma pneumoniae antibody (MP-Ab) was detected by passive agglutination in 67 patients with respiratory tract infection. The results of 6795 tests were analyzed. Results: The positive rate of the test results was 46.4%. The positive rates of male and female patients were 41.7% and 51.9% respectively, with significant difference (P <0.05). There was significant difference among all age groups (P <0.05) 8-year-old to 14-year-old highest positive rate; the seasonal difference was statistically significant, the highest positive rate in autumn. CONCLUSIONS: The rate of MP infection in this area is high; the children aged 3-14 years are at high risk; the infection rate of women is higher than that of men; the incidence of infection in autumn and winter is high; passive agglutination can be used as a routine method for laboratory diagnosis of mycoplasma pneumonia.
