Partial molecular characterization of the mitochondrial genome of Baylisascaris columnaris and prevalence of infection in a wild population of Striped skunks

Members of the genus utilize omnivores or carnivores as their definitive hosts. The best known member of this genus is which is an intestinal parasite of raccoons. The closest relative of is which utilizes the common skunk as its definitive host. Although has been extensively studied, relatively little is known of . For example, the mitochondrial genome of has been sequenced in its entirety. Conversely, the mitochondrial genome of remains largely unexplored. Likewise, the prevalence of this parasite in its wild host has not been documented. In this study, we collected parasites from a wild population of skunks in the state of Utah, United States. The cytochrome c oxidase subunit 1 and 2 genes, NADH dehydrogenase 2 and several tRNA genes were sequenced from the mitochondrial genome of these parasites. We also determined the prevalence of in a wild population of skunks. In this work we identify several novel polymorphic genetic loci between and . These findings provide additional molecular targets for the differentiation of species through clarification of genetic differences between and .
