The and species are widespread and frequent diarrhea-related parasites affecting humans and other mammalian species. The prevalence of these parasites in Mongolia is currently unknown. Therefore, we performed molecular analyses of and in stool samples from 138 patients hospitalized with diarrhea in Mongolia using nested polymerase chain reaction (PCR). A total of 5 (3.62%) and 7 (5.07%) fecal samples were positive for and , respectively. and infections were prevalent in children < 9 years of age. The assemblage-specific fragment patterns for the β-giardin gene of revealed that all five samples testing positive belonged to Assemblage A by the PCR-restriction fragment polymorphism method. For sequencing and phylogenetic analysis of the 18S rDNA and HSP70 genes of all seven patients testing positive the genes were further identified to be of the bovine genotype. This study is the first to report the prevalence of and and its molecular characterization of fecal samples from individuals with diarrhea in Mongolia.
