phylogenetic analysis of the genus cylicocyclus (nematoda: strongylidae) based on nuclear ribosomal sequence species of cylicocyclus ihle, 1922 (nematoda: strongylidae) were collected from donkeys from henan province, china. five samples of each species were selected for sequencing. sixteen different internal transcribed spacer (its) sequences representing the seven species of cylicocyclus were obtained. sequence differences in the first internal transcribed spacer (its-1) among species was lower than that of the second internal transcribed spacer (its-2). phylogenetic analyses were conducted usi ...201323666651
common occurrence of cryptosporidium hominis in horses and donkeys.extensive genetic variation is observed within the genus cryptosporidium and the distribution of cryptosporidium species/genotypes in humans and animals appears to vary by geography and host species. to better understand the genetic diversity of cryptosporidium spp. in horses and donkeys, we characterized five horse-derived and 82 donkey-derived cryptosporidium isolates from five provinces or autonomous regions (sichuan, gansu, henan, inner mongolia and shandong) in china at the species/genotype ...201627264727
