摘 要：Blastocystis is a common intestinal protozoan in humans and various animals worldwide.A few studies have reported the genetic characterization of Blastocystis in pigs in China,but no epidemiological data are available from the Xinjiang Uygur Autonomous *** this study,801 fecal samples were collected from seven scale pig farms in Xinjiang and tested by polymerase chain reaction and sequence analysis of the partial SSU rRNA *** average infection rate of Blastocystis was 21.7%（174/801）;with 7.1 % in pre-weaning piglets,10.0% in post-weaning piglets,31.8% in fattening pigs,and 41.9% in sows（χ=104.89;P 0.01）.Blastocystis subtypes ST1（7/174）,ST3（2/174）,and ST5（165/174） were identified,with subtype ST5 being predominant in each of the pig farms and in each of the age ***3 and ST5 were identified in pre-weaning piglets,and ST1,ST3,and ST5 in post-weaning *** contrast,only the subtype ST5 was observed in fattening pigs and *** polymorphisms were observed at the intra-subtype level,including two variations of ST1（ST1 A,ST1 B）,and seven of ST5（ST5 A to ST5 G）,by sequence alignment analysis and phylogenetic *** studies are needed to elucidate the transmission and public health significance of Blastocystis in pigs in various areas.
