| impact of population structure on genetic diversity of a potential vaccine target in the canine hookworm (ancylostoma caninum). | ancylostoma caninum is a globally distributed canine parasitic nematode. to test whether positive selection, population structure, or both affect genetic variation at the candidate vaccine target ancylostoma secreted protein 1 (asp-1), we have quantified the genetic variation in a. caninum at asp-1 and a mitochondrial gene, cytochrome oxidase subunit 1 (cox-1), using the statistical population analysis tools found in the snap workbench. the mitochondrial gene cox-1 exhibits moderate diversity wi ... | 2007 | 17918358 |
