广州市某大学学生肺炎支原体感染的血清流行病学研究

Sero-epidemiological Study of Mycoylasma Pneumoniae Infections among University Students in Guangzhou

本文报道广州市某大学86年级新生自入学开始至1年半期间内,从先后三次健康检采集血清标本共1064份,应用微量补体结合试验测检其肺炎支原体(MP)抗体,阳性率第一次(1986.9)为者225名,血清的MP补结抗体阳性率(阳转率)分别为0.89%(2/225)、22.42%(50/223)和20.0%(35/175)。第二、三次血清MP补结抗体阳转率较第一次的阳性北有非常显著差异(P值<0.01)。提示该批大学生在入学一年半期间内,可能发生过MP感染的流行。

Mycoplasma pneumoniae antibodies using micro- complement- fixation technic were tested with 1,064 serum samples collected from students of the class of 1935 in a Guangzhou university during three times of physical examination within one and half year after their entering the university. The result showed that [the antibody positive rates of the serum samples collected in September 1986, March 1987 and March 1988 were 1.01%, 19.33% and 18.66% respectively. The antibody positive rates of the 225 students from whom uthree consecutive serum specimens had been collected for antibody testing were 0.89%, 22.42% and 20% respectively. Very significant statistical difference was shown between the antibody positive rate of the serum samples collected from the first time and the antibody positive rate of the serum samples collected from the second and third time. The result suggests that spread of Mycoplasma pneumoniae infections had occurred among the university students within the one and half year period after their university life began.
