Abstract
Little information is available on the epidemiology of Giardia duodenalis in beef cattle from Vietnam. This study was performed to determine the prevalence and genotypes/assemblages of G. duodenalis in native beef calves younger than 6 months in the region. A total of 412 calf fecal samples, randomly selected from 99 small-scale farms located in DacLac and KhanhHoa provinces, central Vietnam, were screened for the presence of G. duodenalis cysts using the zinc-sulfate flotation method followed by iodine staining. The overall prevalence on the sample and herd levels were 13.8 % (57/412) and 42.4 % (42/99), respectively. Molecular analysis in the β-giardin and triosephosphate isomerase genes demonstrated the presence of only G. duodenalis assemblage E in the animals. Since assemblage E has been rarely reported in humans, the zoonotic risk in beef calves in the region appears to be minimal.
