| parasites and associated pathology of the swamp wallaby, wallabia bicolor (marsupialia). | thirty-five swamp wallabies from victoria, new south wales and queensland, australia were examined for parasites. thirty-nine species of nematodes, five species of cestodes and eight species of arthropods were found. wallabies from queensland and northern new south wales had a less diverse helminth fauna (23 species) than did wallabies from southern new south wales and victoria (32 species). rugopharynx spp. and cloacina spp. occurred in large numbers in the stomach but provoked no pathological ... | 1985 | 4078972 |
| phylogenetic relationships of australian strongyloid nematodes inferred from ribosomal dna sequence data. | the sequence of the second internal transcribed spacer of the ribosomal dna was determined for the following strongyloid nematodes: cylicocyclus insignis, chabertia ovina, oesophagostomum venulosum, cloacina communis, cloacina hydriformis, labiostrongylus labiostrongylus, parazoniolaimus collaris, macropostrongylus macropostrongylus, macropostrongylus yorkei, rugopharynx australis, rugopharynx rosemariae, macropostrongyloides baylisi, oesophagostomoides longispicularis and paramacropostrongylus ... | 1997 | 9467733 |
| detection by allozyme electrophoresis of cryptic species of hypodontus macropi (nematoda: strongyloidea) from macropodid marsupials. | allozyme electrophoresis of 98 hypodontus macropi from eight different species of hosts using 24 enzymes revealed a complex of at least six sibling species, with 15-50% fixed genetic differences between taxa. except for the taxon parasitizing macropus rufus/m. robustus, pairs of parasite taxa were, in each case, sympatric at each locality examined, thus supporting the conclusion that they represent valid species. the existence of a series of host-specific nematode taxa explains many of the incon ... | 1992 | 1639562 |
| hypodontus macropi, mönnig, 1929 from a bennetts' wallaby macropus rufogrisea. | hypodontus macropi was found in macropus rufogrisea. males measured 12.73--13.93 mm in length; one female was 19.07 mm in length. the buccal capsule was funnel-shaped. the mouth opening was directed antero-ventrally. there was a pair of large cutting plates on the dorsal margin of the buccal capsule. the brusal rays were well-developed. spicules were equal and each bore a cuticular wing. a gubernaculum and a telamon were present. the vulva was situated near the anus. the female tail, 0.163 mm in ... | 1976 | 1036125 |
| differences in a ribosomal dna sequence of morphologically indistinguishable species within the hypodontus macropi complex (nematoda: strongyloidea). | the nucleotide sequence of the second internal transcribed spacer (its-2) from ribosomal dna has been determined for 3 members of the hypodontus macropi species complex. sequences were compared from nematodes collected from 3 species of australian macropodid marsupial, petrogale persephone, macropus robustus robustus and thylogale billardierii. the its-2 of each operational taxonomic unit ranged from 287 to 292 bases in length, and had a gc content of 36.6-40.1%. differences in nucleotide sequen ... | 1995 | 7635644 |
| hypodontus macropi mönnig, 1929, a hookworm-like parasite of macropodid marsupials. | hypodontus macropi mönnig, 1929, is redescribed and its taxonomic affinities discussed. h. macropi is recorded for the first time from wallabia bicolor, macropus robustus, m. fuliginosus, m. dorsalis, m. agilis and thylogale billardierii. the method of attachment of the parasite and gross and histopathological changes associated with it are described. free living larval stages are described. experimental infestations were attempted but were not successful. hypodontus thetidis johnston and mawson ... | 1979 | 575542 |
| genetic variation within the hypodontus macropi (nematoda: strongyloidea) complex from macropodid marsupial hosts in australia. | genetic variation was investigated in the strongylid nematode hypodontus macropi from macropodid marsupials using the second internal transcribed spacer of ribosomal dna. a total of 547 specimens from ten species of hosts, representing all of the known hosts of the parasite, from across the australian continent was examined. phylogenetic analyses revealed distinct genetic clades in each of macropus agilis, m. dorsalis, m. rufogriseus, m. bicolor, petrogale persephone, thylogale billardierii and ... | 2012 | 23161349 |
| analyses of mitochondrial amino acid sequence datasets support the proposal that specimens of hypodontus macropi from three species of macropodid hosts represent distinct species. | hypodontus macropi is a common intestinal nematode of a range of kangaroos and wallabies (macropodid marsupials). based on previous multilocus enzyme electrophoresis (mee) and nuclear ribosomal dna sequence data sets, h. macropi has been proposed to be complex of species. to test this proposal using independent molecular data, we sequenced the whole mitochondrial (mt) genomes of individuals of h. macropi from three different species of hosts (macropus robustus robustus, thylogale billardierii an ... | 2013 | 24261823 |
| mutation scanning analysis of sequence heterogeneity in the second internal transcribed spacer (rdna) within some members of the hypodontus macropi (nematoda: strongyloidea) complex. | single-strand conformation polymorphism analysis was employed to investigate sequence variation in the second internal transcribed spacer (its-2) of nuclear ribosomal dna within and among individuals representing three operational taxonomic units (otus) of hypodontus macropi from different species of australian macropodid marsupials. of the 96 nematodes analysed, totals of 3 (otu1 from petrogale persephone), 10 (otu2 from macropus robustus) and 7 (otu9 from macropus rufus) representative individ ... | 2001 | 11358128 |
