title: Molecular characterization of Giardia duodenalis from white yaks in China.
abstract: Giardia duodenalis is one of the most common enteric parasites of 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. 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 the 208 white yak fecal samples, four samples (1.92%, all collected in March 2014) tested G. duodenalis-positive by PCR amplification of triosephosphate isomerase (tpi) gene. Sequence analysis confirmed the presence of G. duodenalis assemblage E. The present study revealed the presence and genotype of G. duodenalis in white yaks for the first time, and extended the host range of G. duodenalis. These results provided useful information for further genotyping or subtyping studies of G. duodenalis in white yaks.
