福州地区腹泻病人与肠道原虫感染的关系

The Relationship between Diarrhea and the Infection of Intestinal Protozoa in Fuzhou District

[目的 ]了解福州地区腹泻病人与肠道原虫感染的关系。 [方法 ]通过生理盐水直接涂片法、卢戈氏碘液染色涂片法或改良抗酸染色法对 3 1 1 6名腹泻病人的新鲜粪便进行镜检。 [结果 ]在 3 1 1 6名腹泻病人中 ,肠道原虫感染率为2 1 .6 6 %;弃除 6 3例结肠内阿米巴致病性未获证实外 ,肠道致病原虫的感染率为 1 9.6 4 %。其中以溶组织内阿米巴感染率1 7.6 5 %为最高 ,其次隐孢子虫为 0 .6 4 %,人毛滴虫 0 .6 1 %,人芽囊原虫 0 .4 2 %,蓝贾第鞭毛虫 0 .32 %。 [结论 ]福州地区腹泻病人有 1 9.6 4 %是由肠道致病原虫所引起 ,其中主要是溶组织内阿米巴 ,在儿童中主要是由隐孢子虫、人毛滴虫、人芽囊原虫和蓝贾第鞭毛虫。

To survey the relationship between diarrhea and the infection of intestinal protozoa in Fuzhou district. Microscope examination was carried out for fresh feces derived from 3 116 diarrhea patients by the methods of direct smear with saline, Lugol's solution staining smear or modified acid fast staining, respectively. The infection rate of protocoa was 21.66%.Except 63 cases(Entamoeba coli,the pathogenicity hadn't been proved),the rate of pathogenic intestinal protozoa was 19 64%. Among them the highest rate of Entamoeba histolytic was 17 65%, followed by the rate of Cryptosporidium (0 64%), Trichomonas hominis(0 61%), Blastocystis hominis (0 42%) and Giardia lamblia (0 32%). [Conclusion] The diarrhea was mainly caused by pathogenic intestinal protozoa (19 64%) and the most important was Entamoeba histolytica. For the children, the main organisms of diarrhea ware Cryptosporidium, Trichomonas hominis, Blastocystis hominisand and Giardia lamblia.
