Cryptococcus gattii was diagnosed in two female indoor-housed rhesus macaques. Gross and histopathologic findings included an isolated pulmonary cryptococcoma in a non-SIV-infected macaque and disseminated disease centered on the lungs of an SIV-infected macaque. Fungal yeast were positive with special stains, and the diagnoses were confirmed with a lateral flow assay and PCR.

Thirteen new meroterpenoids, acremorins A-M (1, 2, 4, 6, 7 and 9-16), together with three known analogues (3, 5 and 8) were isolated from the deep-sea-derived fungus Acremonium sclerotigenum LW14 guided by the genomic and OSMAC strategy. Their structures and absolute configurations were established by extensive spectroscopic analysis, electronic circular dichroism (ECD) calculations, Rh(OCOCF)-induced ECD experiments, and a single-crystal X-ray diffraction experiment. Compounds 2, 4, 6 and 9 represent the rare brominated ascochlorins.

Cryptococcosis is a fungal disease in humans and animals, caused by the and species complexes. Clinical cryptococcosis primarily manifests as upper respiratory tract disease; however, dissemination to other organs, particularly the brain, can occur. Nasal colonisation and subclinical cryptococcosis are common in koalas () due to their shared environmental niche with : trees.

Cryptococcus gattii is a saprophytic basidiomycete that grows in the environment and can cause systemic cryptococcosis. Ocular cryptococcosis causes blindness and is commonly associated with central nervous system (CNS) infection. Toll-like receptor 9 (TLR9) can control cryptococcosis and another mycosis.

Background: Infection by Cryptococcus gattii can lead to pulmonary or central nervous system (CNS) disease, or both. Whether site of infection and disease severity are associated with C. gattii species and lineages or with certain underlying medical conditions, or both is unclear.
