| muscleworms, parelaphostrongylus andersoni (nematoda: protostrongylidae), discovered in columbia white-tailed deer from oregon and washington: implications for biogeography and host associations. | parelaphostrongylus andersoni is considered a characteristic nematode infecting white-tailed deer (odocoileus virginianus). host and geographic distribution for this parasite, however, remain poorly defined in the region of western north america. fecal samples collected from columbia white-tailed deer (o. v. leucurus) in a restricted range endemic to oregon and washington, usa, were examined for dorsal-spined larvae characteristic of many protostrongylid nematodes. multilocus dna sequence data ( ... | 2008 | 18263818 |
