Abstract
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 T. stigmatica. A further clade contained all specimens from M. robustus and M. rufus, together with two examples of host switching by nematodes into M. fuliginosus. The latter clade was subdivided int..
