muellerius capillaris (mueller, 1889) (nematoda: protostrongylidae): an unusual finding in rocky mountain bighorn sheep (ovis canadensis canadensis shaw) in south dakota.lungs and fecal samples from nine hunter-killed rocky mountain bighorn sheep were examined for lungworms. all samples contained adults and/or larvae of muellerius capillaris (mueller, 1889). protostrongylus spp., the lungworms commonly reported from bighorn sheep, were not present in any samples. larvae of m. capillaris bear a spine on the dorsal side of the posterior end and are shorter than dorsal-spined larvae of other lungworms recorded from north american ungulates. larvae similar in shape ...19846530714
bighorn sheep, a new host record for parelaphostrongylus odocoilei (nematoda: protostrongylidae).larval nematodes with a dorsal spine on the tail were recovered from fecal samples of california bighorn sheep (ovis canadensis californiana) in northeastern washington state, usa. the identity of these dorsal-spined larvae (dsl) was established by single-strand conformation polymorphism (sscp) analyses of a partial fragment of the first internal transcribed spacer of the ribosomal dna. the sscp profiles of individual dsl from bighorn sheep were compared with those of dsl of five protostrongylid ...200617255460
