| 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 |
