目的了解入伍新兵人群肺炎支原体(MP)IgG抗体的流行分布情况,为今后预防MP感染及其引发的相关疾病提供科学依据。方法采用血清流行病学调查方法,利用酶联免疫吸附试验(ELISA)技术,对北京军区空军近8年来自16个省市的364名入伍新兵血清进行了MP IgG抗体检测并进行统计分析。结果来自16个省市8年间入伍的364名新兵,发现历年间和地区间抗体阳性率差异无统计学意义;河北省、陕西省和黑龙江省阳性率较高,均为100.00%,甘肃省(73.71%)、福建省(81.82%)和山西省(82.61%)相对较低,阳性率73.71%~100.00%,平均阳性率为91.21%。入伍前工作与否,抗体阳性检出率差异无统计学意义。结论健康新兵人群高抗体水平,MP不易在新兵人群中流行。
Objective To understand the epidemiological distribution of Mycoplasma pneumoniae (MP) IgG antibody in service recruits and to provide a scientific basis for future prevention of MP infection and its related diseases. Methods Serum epidemiological investigation method was used to detect MP IgG of 364 recruit serogroups from 16 provinces and cities in Beijing Military Region Air Force in the past 8 years by enzyme-linked immunosorbent assay (ELISA) and statistical analysis was performed. The results came from 364 recruits recruited from 16 provinces and cities in 8 years. There was no significant difference in antibody positive rate between years and regions. The positive rate was 100.00% in Hebei Province, Shaanxi Province and Heilongjiang Province, 73.71%). Fujian Province (81.82%) and Shanxi Province (82.61%) were relatively low with a positive rate of 73.71% -100.00%. The average positive rate was 91.21%. There was no significant difference in the detection rate of positive antibody before work or not. Conclusion The level of high antibody in healthy recruits is not easy to popularize in new recruits.
