Abstract

To examine whether Ostertagia mossi and Ostertagia dikmansi from white-tailed deer (Odocoileus virginianus) are separate species, we obtained DNA sequences for the cytochrome C oxidase subunit I and internal transcribed spacer 2 gene targets for phylogenetic analyses. Neither target revealed separation between morphotypes, confirming they are the same species and providing new data on Ostertagia morphotypes.
