Globocephaloides trifidospicularis

Macropus rufogriseus; M. giganteus (host numbers not given)

24 isozymes (see Table 1)

Two host-specific species, with 4 fixed differences. ITS1 and ITS2 sequencing later failed to detect these species [26]

[190]

Hypodontus macropi

3 Macropus agilis; 4 M. dorsalis; 1 M. rufogriseus rufogriseus; 1 M. rufogriseus banksianus; 2 M. robustus robustus; 1 M. robustus erubescens; 2 M. rufus; 3 M. fuliginosus; 2 Wallabia bicolor; 2 Thylogale billardierii

28 isozymes

Six species detected, with fixed differences at 20–50% of loci. One in M. r. erubescens, M. r. robustus, M. rufus and M. fuliginosus, one in M. r. banksianus and M. r. rufogriseus, and one in each other host. Species status of nematodes in M. r. robustus, T. billardierii and M. bicolor later supported in [191]

[27]

23 isozymes

R. omega from each host species had fixed differences at 10 loci. R. omega from T. stigmatica named Rugopharynx sigma

[192]

Paramacropostrongylus typicus

4 Macropus fuliginosus; 2 M. giganteus

37 isozymes

P. typicus from each host species had fixed differences at 10 loci. P. typicus from M. giganteus named Paramacropostrongylus iugalis. Hybridisation later detected [193]

[194]

Macropostrongylus baylisi

2 Macropus giganteus; 15 M. robustus robustus; 4 M. r. erubescens; 15 M. parryi

27 isozymes
