TL;DR: It is indicated that the Myxozoa are closely related to Cnidaria, and marine taxa at the genus level branch separately from genera that usually infect freshwater fishes; taxa cluster more by development and tissue location than by spore morphology.

TL;DR: Through morphological and molecular analyses, the presence of both K. thyrsites and K. amamiensis are confirmed in eastern Australian waters and a novel Kudoa species was identified, having stellate spores, with one polar capsule larger than the other three.

TL;DR: A new protozoan of the genus Perkinsus is described from the muscle and hemolymph of the blacklip abalone, Haliotis ruber, from South Australia, and appears to be uninfective to oysters.

TL;DR: Severe branchitis associated with Paramoeba infection has emerged as the major infectious disease of sea-caged salmonids in Australia and affected fish suffer from anorexia and respiratory distress.

TL;DR: The morphology and cytopathology of GAV closely resemble that observed for lymphoid organ virus (LOV) from Australia and yellow-head virus (YHV) from Thailand, and molecular data are required to determine the phylogenetic relationships and appropriate taxonomic classification of these 3 prawn viruses.
