RESUMO
Polyglucosan bodies (Lafora bodies) were identified in a juvenile gray-headed flying fox (Pteropus poliocephalus) with neurological signs. The structures were only noted in the brain stem, and no associated degenerative changes were present. These structures have not been previously identified in any species in the order Chiroptera.

An alpaca (Llama pacos), born and raised in Australia, was presented with multiple subcutaneous abscesses. Histological findings indicated a severe necrotizing and histiocytic myositis and cellulitis associated with central caseation and multiple sarcocysts. Ultrastructural examination supported the diagnosis; however, cyst wall characteristics were not consistent with the 2 known species found in alpacas. While seroconversion in camelids is reported to be near ubiquitous, myositis is rare, and this is the first case reported outside of the Americas.

Two outbreaks of mortality in juvenile barramundi (Lates calcarifer) with a high prevalence of gastrointestinal cryptosporidiosis are described. Juvenile barramundi at a separate hatchery and grow-out facility were demonstrating markedly increased mortality rates. Histological examination in all cases indicated a heavy infection of Cryptosporidium-like organisms within the distal stomach and proximal small intestine. Electron microscopy confirmed a diagnosis of cryptosporidiosis; however, speciation was not possible.
