a survey of domestic animals to detect serological responses against legionella spp. by indirect fluorescent hundred ninety-six (196) animal sera were examined for antibodies against heat-killed antigens of legionella pneumophila serogroups 1 to 5, l. bozemanii, l. dumoffii, l. gormanii and l. micdadei by the indirect fluorescent antibody technique. only two animals (1%), both sheep, reacted against l. pneumophila serogroups at a titer of 256. however, 29% of the horses and 24% of the sheep tested were reactive to at least one non-l. pneumophila legionella spp. antigen at a titer of 256. at a titer ...19836357411
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
