چکیده انگلیسی
Present study was performed to identify the species of ascarids from macaw parrot, Ara chloroptera, in China. Total 6 ascarids (3 males and 3 females) were collected in the feces of 3 macaws at Guangzhou Zoo in Guangdong Province, China. Their morphological characteristics with dimensions were observed under a light microscope, and their genetic characters were analyzed with the partial 18S rDNA, ITS rDNA and nad4 gene sequences, respectively. Results showed that all worms have no interlabia but male worms have two alate spicules, well-developed precloacal sucker and a tail with ventrolateral caudal alae and 11 pairs of papillae. The partial 18S rDNA, ITS rDNA and nad4 sequences were 831Â bp, 1015Â bp and 394Â bp in length, respectively. They showed the highest similarity of 99.8% (18S rDNA) with Ascaridia nymphii, 93.8% identities (ITS rDNA) with A. columbae and 98.5% to 99.5% identities (nad4) with Ascaridia sp. from infected parrot. All Ascaridia nematodes from the macaws were clustered into one clade and formed monophyletic group of Ascaridia with A. columbae and A. galli in two phylogenetic trees. It is observed that the combining morphological and sequencing data from three loci, the present Ascaridia species was identified as Ascaridia nymphii, which is the first record of A. nymphii from macaw parrot in China.
