Efficient communication with the environment is critical for all living organisms. Fungi utilize
complex signalling systems to sense their environments and control proliferation …

Cryptococcus neoformans is a pathogenic fungus that causes meningitis worldwide,
particularly in human immunodeficiency virus (HIV)–infected individuals. Although …

Melanins are implicated in the pathogenesis of several human diseases, including some
microbial infections. In this study, we analyzed whether the conidia and the yeasts of the …

Natural brown–black eumelanin pigments confer structural coloration in animals and
potently block ionizing radiation and antifungal drugs. These functions also make them …

Melanin is made by several important pathogenic fungi and has been implicated in the
pathogenesis of a number of fungal infections. This study investigated whether the thermally …

Cryptococcus neoformans is a human pathogenic fungus which is unusual in two respects: it
has a polysaccharide capsule similar to that found in encapsulated bacteria and it can …

A naturally occurring Mel-variant of Cryptococcus neoformans was isolated from the wild
type. The effect of phenoloxidase activity on virulence was analyzed on genetically …

Melanins are complex biological pigments formed by the oxidative polymerization of
phenolic and/or indolic compounds. These pigments have been implicated in the …

Sporothrix schenckii is a human pathogen that causes sporotrichosis, an important
cutaneous mycosis with a worldwide distribution. It produces dark-brown conidia, which …

Using techniques developed to study melanization in other fungi, we demonstrate that
Coccidioides posadasii arthroconidia, spherules, and endospores produce melanin or …
