Susceptibility of melanized and nonmelanized Cryptococcus neoformans to nitrogen- and oxygen-derived oxidants.

Y Wang1, A Casadevall.   

Abstract

Melanized Cryptococcus neoformans cells were less susceptible than nonmelanized cells to the fungicidal effects of nitrogen- and oxygen-derived oxidants. The results support the hypothesis that the phenoloxidase enzyme system contributes to virulence by protecting C. neoformans against nitrogen- and oxygen-derived oxidative antimicrobial molecules produced by immune effector cells.
