Using techniques developed to study melanization in other fungi, we demonstrate that Coccidioides posadasii arthroconidia, spherules, and endospores produce melanin or melanin-like compounds in vitro and tissue forms synthesize pigment in vivo. Since melanin is an important virulence factor in other pathogenic fungi, it may affect the pathogenesis of coccidioidomycosis.
