本文报告了1988年秋季四川省成、渝等四市、县年龄在4～6岁、17～65岁之间的502名健康人群用微量凝集试验检测的嗜肺性军团菌(Lp)Ⅱ～Ⅶ型的抗体水平。此次的检测结果,Lp抗体阳性率(≥1∶16)合计为35.21％,其中LpⅢ型的抗体阳性率为26.29％,LpⅢ型在各型中最高,其他型较低,从而说明四川省广泛存在着LpⅡ～Ⅷ型的感染,而且在多型性感染中,LpⅢ型为明显的优势菌型,其流行病学意义有待进一步地研究。此次出现高的抗体阳性率提示这与嗜肺性军团菌在人群中广泛传播有关,应予以高度的重视。
This article reports the results of the detection of L. pneumophila Ⅱ (Lp) by 502 micro-agglutination test in 502 healthy people aged 4 ~ 6 years and 17 ~ 65 years old in four cities and counties of Sichuan Province, Chengdu and Chongqing in autumn of 1988, Ⅶ type antibody levels. In this test, the positive rate of Lp antibody (≥1:16) was 35.21%, of which the positive rate of LpⅢ antibody was 26.29%. The LpⅢtype was the highest in all genotypes and the others were lower, There is Lp Ⅱ ~ Ⅷ type infection, and in polytype infection, Lp Ⅲ type is obvious dominant bacteria, its epidemiological significance needs further study. The high antibody positive rate suggests that it is related to the wide spread of Legionella pneumophila in the human population and deserves a high degree of attention.
