Twenty-one (2.6%) of the specimens from five farms were <jats:italic>G. duodenalis-<\/jats:italic>positive, with a significant difference in prevalence among different farms (0\u20138.7%) (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.01). <jats:italic>Giardia duodenalis<\/jats:italic> prevalence was highest in fattening pigs (5.4%, 7\/129), followed by sows (3.2%, 7\/222), post-weaning piglets (1.8%, 5\/281), and pre-weaning piglets (1.2%, 2\/169), but there was no significant difference in prevalence among the age groups (<jats:italic>p<\/jats:italic>\u00a0&gt;\u00a00.05). Sequence analysis of the SSU rRNA gene revealed that the 21 <jats:italic>G. duodenalis<\/jats:italic> strains belonged to three assemblages: A (<jats:italic>n<\/jats:italic>\u00a0=\u00a02), B (<jats:italic>n<\/jats:italic>\u00a0=\u00a016), and E (<jats:italic>n<\/jats:italic>\u00a0=\u00a03). Assemblage B was the predominant assemblage and was widely distributed in all <jats:italic>G. duodenalis<\/jats:italic>-positive farms and age groups. All <jats:italic>G. duodenalis<\/jats:italic>-positive specimens were further assayed at the \u03b2-giardin (<jats:italic>bg<\/jats:italic>), glutamate dehydrogenase (<jats:italic>gdh<\/jats:italic>), and triosephosphate isomerase (<jats:italic>tpi<\/jats:italic>) genes, and two <jats:italic>tpi<\/jats:italic>, four <jats:italic>gdh,<\/jats:italic> and two <jats:italic>bg<\/jats:italic> sequences were identified. These data indicate that pigs may be a zoonotic risk and can potentially spread <jats:italic>G. duodenalis<\/jats:italic> infection from animals to humans.<\/jats:p>","DOI":"10.1051\/parasite\/2019056","type":"journal-article","created":{"date-parts":[[2019,8,26]],"date-time":"2019-08-26T07:57:03Z","timestamp":1566806223000},"page":"53","source":"Crossref","is-referenced-by-count":13,"title":["Detection
