BACKGROUND: A number of epidemiological studies have demonstrated Giardia as prevalent in both humans and dogs worldwide and have postulated the occurrence of anthroponotic, zoonotic and animal-specific cycles of transmission, which may be geographically and regionally unique in its epidemiology. The aim of this study was to utilise molecular tools to determine the prevalence and compare genotypes of Giardia duodenalis infecting humans and dogs living in a previously identified Giardia-endemic village in rural Cambodia in order to ascertain zoonotic transmission risk. FINDINGS: The prevalence of G. duodenalis in humans and dogs was 18.3% (40/218) and 10.6% (10/94) by PCR, respectively. Molec..View full abstract
