Abstract
This case is reported with the intention of highlighting the presentation of cutaneous myxosporidiasis in Australian tree frog (Litoria caerulea) caused by genus Myxobolus. The morphology and morphometric characteristic of the spores were determined using light microscopy and differential interference contrast microscopy. Spores were pyriform in shape in frontal view and oval in lateral view, and the average size was respectively 11.4 × 6.0 × 4.5 μm (12.1 - 9.5 × 6.3 - 5.4 × 5.0 - 4.1 μm). To the best of our knowledge, this is the second case of skin invasion caused by myxosporeans in amphibians.
