| genetic variability among trichuris ovis isolates from different hosts in guangdong province, china revealed by sequences of three mitochondrial genes. | this study examined sequence variation in three mitochondrial dna (mtdna) regions, namely cytochrome c oxidase subunit 1 (cox1), nadh dehydrogenase subunit 5 (nad5) and cytochrome b (cytb), among trichuris ovis isolates from different hosts in guangdong province, china. a portion of the cox1 (pcox1), nad5 (pnad5) and cytb (pcytb) genes was amplified separately from individual whipworms by pcr, and was subjected to sequencing from both directions. the size of the sequences of pcox1, pnad5 and pcy ... | 2013 | 22928806 |
