    Infectious diseases are contributing to the decline of endangered amphibians. We identified myxosporean parasites, Myxidium spp. (Myxosporea: Myxozoa), in the brain and liver of declining native frogs, the Green and Golden Bell frog (Litoria aurea) and the Southern Bell frog (Litoria raniformis). We unequivocally identified two Myxidium spp. affecting Australian native frogs and the invasive Cane toad (Bufo marinus, syn. Rhinella marina; brought to Australia in 1935, via Hawaii) and demonstrated their association with disease. We showed that the Australian brain and liver Myxidium spp. differed 9%, 7%, 34% and 37% at the small subunit rDNA, large subunit rDNA, internal transcribed spacers 1 and 2, but were distinct from Myxidium cf. immersum from Cane toads in Brazil. It is unlikely that the Cane toad brought the myxosporean parasites to Australia. This work emphasizes the importance of accurate species identification of pathogens relevant to wildlife management and disease control.
