Abstract |
In Nepal, gastrointestinal infections due to parasites including Entamoeba species are common. The main aim of this study was to identify species of Entamoeba using genotypic analysis. The prevalence of Entamoeba infections was examined by PCR in fecal samples from 143 inhabitants living close to wild rhesus macaques in Kathmandu, Nepal. The numbers of positive cases were one (0.7%) for E. histolytica, eight (5.6%) for E. dispar, seven (4.9%) for E. coli, and two (1.4%) for E. chattoni (E. polecki ST2). No infections with E. nuttalli, E. moshkovskii, and E. polecki ST1 were found. In E. dispar, at least seven different genotypes were detected from the eight samples by sequence analysis of tRNA-linked short tandem repeats. Different genotypes were found even in a couple from the same family. This is the first report demonstrating that E. dispar with high genotypic diversity is prevalent, rather than E. histolytica, in Kathmandu, and that zoonotic transmission of E. chattoni from rhesus macaques might occur in the inhabitants. |
