Although previous epidemiological surveys in Ecuador indicate the presence of Entamoeba histolytica, prevalence data of this parasite remain scarce. Most of the studies were based on microscopic examination, which does not allow a morphological differentiation from the non-pathogenic Ent. dispar and Ent. moshkovskii. In the present study, 674 stool samples from a South Ecuadorian rural community were screened for Entamoeba spp. Subsequently, molecular identification was performed on 101 samples containing Ent. histolytica/Ent. dispar/Ent. moshkovskii cysts. The study indicated the absence of Ent. histolytica in this South Ecuadorian community and confirmed the difficulty of differentiating Entamoeba spp. based on morphological features.
尽管厄瓜多尔之前的流行病学调查表明存在溶组织内阿米巴，但这种寄生虫的流行数据仍然很少。大多数研究都是基于显微镜检查，这不能将其与非致病性的迪斯帕内阿米巴和莫氏内阿米巴区分开来。在本研究中，对厄瓜多尔南部一个农村社区的 674 份粪便样本进行了溶组织内阿米巴属的筛查。随后，对含有溶组织内阿米巴/迪斯帕内阿米巴/莫氏内阿米巴包囊的 101 份样本进行了分子鉴定。研究表明，在这个厄瓜多尔南部社区中不存在溶组织内阿米巴，这也证实了基于形态特征区分内阿米巴属的困难。
