a nearctic parasite in a palearctic host: parelaphostrongylus andersoni (nematoda; protostrongylidae) infecting semi-domesticated reindeer in alaska. | parelaphostrongylus andersoni is a muscle-dwelling protostrongylid nematode that infects caribou and white-tailed deer across north america, and can cause significant muscular and pulmonary pathology in these species. we collected 44 fecal samples from semi-domesticated reindeer (rangifer tarandus tarandus) from the kakarak herd of western seward peninsula, alaska, usa. this herd has no record of historical contact and extremely limited possibility of contemporary contact with native grant's car ... | 2013 | 24533324 |
experimental studies of elaphostrongylus rangiferi in reindeer (rangifer tarandus tarandus): life cycle, pathogenesis, and pathology. | a total of 12 reindeer calves (rangifer tarandus tarandus) were given 200-1,000 infective larvae of elaphostrongylus rangiferi and autopsied 2 1/2-196 days post inoculation (p.i.). the larvae penetrated venules of the abomasal wall and followed the bloodstream via the liver to the lungs. in the lungs the larvae entered pulmonary venules and spread to all tissues via the general circulation. many larvae that lodged in arterial vessels outside the spinal cord migrated into the cord along the spina ... | 1994 | 7839758 |
humoral immunity and output of first-stage larvae of elaphostrongylus rangiferi (nematoda, metastrongyloidea) by infected reindeer, rangifer tarandus tarandus. | the use of an indirect immunofluorescence technique demonstrated that serum from reindeer, rangifer tarandus tarandus, infected with elaphostrongylus rangiferi (nematoda, metastrongyloidea) contained antibodies directed against antigen(s) on the cuticle of the parasites first-stage larvae (l1). output of l1 from the male reindeer was low in the period june to august, but increased to a higher level during the rutting season (september to october). the titre of specific antibody showed an inverse ... | 1984 | 6371122 |
cerebrospinal elaphostrongylosis in sheep in northern norway. | pathologic examination of four sheep from northern norway exhibiting neurologic signs of paresis, paralysis and vestibular system disease revealed nematodes in the central nervous system (cns). the worms were identified as elaphostrongylus rangiferi mitskevich, 1960, the elaphostrongylid nematode of reindeer (rangifer tarandus tarandus). microscopic lesions found in the cns were focal traumatic encephalomyelomalacia caused by migrating worms, eosinophilic meningitis and choroiditis, lymphohistio ... | 1991 | 1796689 |
cerebrospinal elaphostrongylosis in dairy goats in northern norway. | ten carcasses and three vertebral columns from north norwegian dairy goats, which had been killed due to clinical signs of severe neurologic disease, were received for necropsy. pathological examination revealed nematodes and nematode ova in the central nervous system (cns) of nine goats. worms found by gross examination were identified as elaphostrongylus rangiferi mitskevich, 1960. focal traumatic encephalomyelomalacia, apparently caused by migrating worms, perivascular cuffing, eosinophilic l ... | 1991 | 1796688 |
