Infections due to Cryptococcus neoformans/C. gattii complex have been reported to afflict, not only humans but also other mammals including seabirds and cetaceans, proving that the actual animal exposure to these fungi in nature could be underestimated. In this study, antifungal activity of ethanolic extracts obtained from red alga Asparagopsis taxiformis was evaluated against eight major genotypes of the C. neoformans/C. gattii complex, using both disk diffusion and microdilution broth methods.

Abstract

Infections due to Cryptococcus neoformans/C. gattii complex have been reported to afflict, not only humans but also other mammals including seabirds and cetaceans, proving that the actual animal exposure to these fungi in nature could be underestimated. In this study, antifungal activity of ethanolic extracts obtained from red alga Asparagopsis taxiformis was evaluated against eight major genotypes of the C. neoformans/C. gattii complex, using both disk diffusion and microdilution broth methods. The algal extracts were active against all fungal strains tested and were not cytotoxic to human red blood cells. This study suggests that Asparagopsis taxiformis extracts possess attractive antifungal properties which should encourage the search for new drugs derived from marine algae
