A survey of parasites from 39 stool specimens taken from 36 Indochinese refugees who are now living in Utah County, Utah, indicated representative intestinal helminths (worms), and protozoans upon clinical examination. Approximately 75% of the stools contained nematodes, and 55.5% had protozoans. Parasites found were Entamoeba coli, Chilomastix mesnili, Endolimax nana, Giardia lamblia, lodamoeba buetschlii, Clonorchis sinensis, Trichuris trichiura, Ascaris lumbricoides, and Plasinodium vivax. The most common protozoan observed was Entamoeba coli (1979 and 1980) while the most common helminths were Ascaris lumbricoides) (1979) and Clonorchis sinensis (1980). These data were comparable to studies of refugees at two other laboratories in Utah and one at Washington, D.C.
