健康青年沙眼衣原体感染血清流行病学调查

目的了解入伍新兵人群沙眼衣原体（CT）IgG抗体的流行分布情况，为今后预防CT感染提供科学依据。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，对北京军区近8年来自16个省市的364名入伍新兵血清进行CT—IgG抗体检测并进行统计分析。结果2001--2008年入伍新兵CT—IgG阳性率为4．35％～15．56％，平均为10．71％，8年间抗体阳性率差异无统计学意义（P〉0．05）；来自16个省市的新兵，其中江苏省（26．09％）、陕西省（26．09％）、天津市（21．74％）抗体阳性率较高，其余省市相对较低，阳性率4．35％～26．09％，平均阳性率为10．71％。入伍前工作与否，抗体阳性检出率无显著性差别。结论健康青年人群CT抗体水平较低，人群易感性高，应加强健康教育，提高防病知识水平。

Serological investigation on CT infection among healthy young adults

Objective ] To investigate the distribution of chlamydia trachomatics（ CT ） antibody IgG in recruits, and provide scientific evidence for further prevention. Methods ] A serological study was conducted by using Enzyme-Linked Immuno Sorbent Assay （ ELISA） ,serum samples of 364 recruits , who came from 16 provinces during the past 8 years, were tested to detect CT antibody IgG and the overall positive rate was analyzed statistically. Results] The positive rate of CT-IgG was 4.35% -15.56% among re- cruits from 2001-2008, with 10.71% in average, and the positive rate was not significantly different between 8 years （P 〉 0.05）. The higher level found in recruits from Jiangsu（26.09% ）, Shanxi（26.09%） and Tianjin（ 21.74% ）, and the recruiters from oth- er regions were at a lower level. The positive rates ranged from 4.35%-26.09%, with 10.71% in average. There was no signifi- cant difference of the antibody positive rate between the recruiters with occupation background or not before their recruitment. Conclusion] CT antibody level is relatively low among healthy young adults, CT susceptibility is high among them. It is necessary to enhance healthy education to improve the level of knowledge of disease control.
