近20年来,世界许多地方阿米巴病的粪检阳性率都有下降的趋势,我国下降尤为明显。但血清学调查表明,溶组织内阿米巴(简称阿米巴)抗体阳性率远较虫体阳性率高得多。郭增柱等(1984)用粪检法结合酶联免疫吸附试验(ELISA)检查北京丰台区和甘肃张掖县的人群,发现血清阳性率较粪检阳性率高出3～6倍。我国南方各地尚缺这方面的报道。我们在江西省信丰县大塘乡樟塘村作了这方面的调查,现报告如下。
In the past 20 years, the positive rates of stool tests for amebiasis in many parts of the world have been declining, especially in China. However, serological investigations showed that the positive rate of antibody in Entamoeba histolytica (amoeba) was far higher than that in parasites. Guo Zengzhu et al. (1984) examined the population of Fengtai District of Beijing and Zhangye County of Gansu Province by fecal examination and enzyme-linked immunosorbent assay (ELISA), and found that the positive rate of seropositivity was 3-6 times higher than that of fecal examination. There is still a lack of coverage in southern China. We have made a survey in this area in Zhangtang Village, Datang Township, Xinfeng County, Jiangxi Province. The report is as follows.
