| genetic variability among dicrocoelium dendriticum isolates from different regions in shaanxi province, china revealed by sequences of three mitochondrial genes. | the genetic variations in three mitochondrial dna (mtdna) regions, namely portion of cytochrome c oxidase subunit 1 (pcox1), nadh dehydrogenase subunit 1 (pnad1) and cytochrome b (pcytb), were examined for dicrocoelium dendriticum samples isolated from different origins in shaanxi province, northwestern china. the intra-specific sequence differences within d. dendriticum samples were 0-0.52% for pcox1, 0-0.73% for pnad1 and 0-0.58% for pcytb. phylogenetic analyses based on combined sequences of ... | 2013 | 23521316 |
