云南省钩端螺旋体病健康人血清显凝试验报告

A Report of Leptospirosis Microagglutination Test on Healthy Human Sera in Yunnan

本文报道１９７０年－１９９４年在我省１７个地州市进行钩端螺旋体病健康人血清显凝试验检测结果：被检县占６６．９３％（８５／１２７）；人群自然感染率平均为２６．９３％（３９１３／１４５２９）；血清群分属１４个，其中以黄、秋、波、澳、犬、赛、流、塔等８群为主，合占８０．８８％；抗体ＧＭＴ值在不同人群间有所差异，但无显著性意义；感染率在普通农民与畜牧从业人群间有非常显著性差异（ｘ２＝４０９．４３Ｐ＜０．００５）；感染率在不同地理层次的人群间亦有非常显著性差异：高寒层与中暖层比，ｘ２＝７２．２７Ｐ＜０．００５；高寒层与低热层比，ｘ２＝１６１．６８Ｐ＜０．００５；中暖层和低热层比，ｘ２＝１１５．６１Ｐ＜０．００５。这些血清地理流行病学特征，与我省钩体病流行严重、分布面广、菌群复杂以及地势呈梯层垂直分布的特点是相一致的。

This paper reported the results of leptospirosis microagglutination test on healthy human sera obtained from 17 districts in yunnan from 1970 to 1974. 85 counties were detected(66. 93%);the average human infection rate was 26.93% (3913/14529). The variation of infection rate between average farmers and professional veterinarians was very significant (x2=409.43, P<0. 005); the variation of infection rate of human groups in different geographic altitudes was also significant.
