| sequence variation in two mitochondrial dna regions and internal transcribed spacer among isolates of the nematode oesophagostomum asperum originating from goats in hunan province, china. | the present study examined sequence variability in two mitochondrial dna (mtdna) regions, namely cytochrome c oxidase subunit 1 (cox1) and nadh dehydrogenase subunit 1 (nad1), and internal transcribed spacer (its) of nuclear ribosomal dna (rdna) among oesophagostomum asperum isolates from goats in hunan province, china. a portion of the cox1 (pcox1), nad1 (pnad1) genes and the its (its1+5.8s rdna+its2) rdna were amplified by polymerase chain reaction (pcr) separately from adult o. asperum indivi ... | 2016 | 25226270 |
| genetic variability in the three mitochondrial genes among oesophagostomum asperum isolates from different regions in shaanxi and hunan provinces, china. | the present study examined sequence variations in three mitochondrial dna (mtdna) regions, namely, nadh dehydrogenase subunit 5 (nad5), adenosine triphosphate subunit 6 (atp6) and cytochrome c oxidase subunit 3 (cox3), among oesophagostomum asperum isolates from different regions in shaanxi and hunan provinces, china. the lengths for partial sequences of nad5 (pnad5), atp6 (patp6) and cox3 (pcox3) were 427 bp, 381 bp and 337 bp, respectively. the intra-specific sequence variations among all o. a ... | 2014 | 23795833 |
