　　Background: Giardia duodenalis is one of the most common enteric parasites in humans and animals,including companion animals,livestock and wildlife.To date,the information about the prevalence and molecular characterization of G.duodenalis infection in white yaks was limited.Results: In the present study,a total of 208 white yak fecal samples were collected from Tianzhu Tibetan Autonomous County(TTAC)between September 2013 and March 2014.Of 208 white yak fecal samples,four samples(1.92%,all collected in March 2014)were tested G.duodenalis-positive by PCR amplification of triosephosphate isomerase(TPI)gene.Neighbor-Joining(N J)analysis was carried out to identify the G.duodenalis assemblages in Mega 5.0 software,then only assemblage E was determined in the present study.Conclusions: The present study not only revealed the presence and genotype of G.duodenalis in white yaks for the first time,but also extended the host range of G.duodenalis.The results will provide useful information for further prevention and the control of the G.duodenalis infection.
