医务人员肺炎支(衣)原体感染的流行病学调查

Epidemiological Survey on Mycoplasma pneumoniae and Chlamydia pneumoniae Infection in Medical Workers

目的 了解医院医务人员肺炎支（衣）原体既往感染状况。方法 采用固相酶联免疫吸附（ELISA）方法,对健康医务人员分组抽取静脉血进行肺炎支（衣）原体特异性IgG和IgM 4项检测;以献血员血清为对照试验组。结果150名医务人员肺炎支（衣）原体特异性抗体总体检测阳性率为65.3％,献血员为52.9％,两组相比差异有显著性（P<0.05）;调查期间医务人员曾有呼吸道感染症状者,暴露组和非暴露组差异有显著性（P<0.05）;但肺炎支（衣）原体特异性抗体检测阳性率两组比较差异无显著性（P>0.05）。结论 医院医务人员肺炎支（衣）原体感染率较高,应重视肺炎支（衣）原体感染的预防、诊断和治疗。

OBJECTIVE To investigate status of infection by Mycoplasma pneumoniae (MP) and Chlamydia pneu-moniae (CP) in medical workers. METHODS The specific IgG and IgM of MP and CP were determined by the solid phase ELISA in medical workers and blood donors served as control group. RESULTS The positive rate of the specific IgG and IgM, was 65. 3% and 52. 9%, respectively in 150 medical workers and the blood donors. There was a significant difference in the positive rate between them (P<0. 05). The rate of the respiratory tract infection in the exposed group was significantly different from that in the nonexposed one, but the positive rate of the specific IgG and IgM in the exposed group was insignificantly different from that in the nonexposed one. CONCLUSIONS The infective rate of MP and CP is higher in medical workers than that in blood donors. Prevention, diagnosis and treatment of MP and CP infection should be paid a great attention to medical workers.
