| characterization of baylisascaris schroederi from qinling subspecies of giant panda in china by the first internal transcribed spacer (its-1) of nuclear ribosomal dna. | in the present study, a total of 20 nematode isolates, (including 10 male and 10 female worms) representing baylisascaris schroederi from 5 qinling subspecies of giant pandas (ailuropoda melanoleuca) in shaanxi province of china, were characterized and grouped genetically by the first internal transcribed spacer (its-1) of nuclear ribosomal dna (rdna). the rdna fragment spanning 3' end of 18s rdna, complete its-1 rdna, and 5' end of 5.8s rdna were amplified and sequenced. the sequence variabilit ... | 2011 | 21870244 |
| genetic variability of baylisascaris schroederi from the qinling subspecies of the giant panda in china revealed by sequences of three mitochondrial genes. | the present study examined the variations in three mitochondrial (mt) dna sequences, namely cytochrome b (cytb), cytochrome c oxidase subunit 3 (cox3) and nadh dehydrogenase subunit 5 (nad5), among baylisascaris schroederi isolates from the qinling subspecies of the giant panda in shaanxi province, northwestern china. no differences in length were detected in the three mt fragments from different isolates. the intra-specific sequence variations within all b. schroederi samples were 0-2.6% for pc ... | 2014 | 23656289 |
| phylogenetic study of baylisascaris schroederi isolated from qinling subspecies of giant panda in china based on combined nuclear 5.8s and the second internal transcribed spacer (its-2) ribosomal dna sequences. | the nuclear ribosomal dna (rdna) region spanning 5.8s rdna and the second internal transcribed spacer (its-2) of baylisascaris schroederi isolated from the qinling subspecies of giant panda in shaanxi province, china were amplified and sequenced. sequence variations in the two rdna regions within b. schroederi and among species in the family ascarididae were examined. the lengths of b. schroederi 5.8s and its-2 rdna sequences were 156 bp and 327 bp, respectively, and no nucleotide variation was ... | 2012 | 22402105 |
