Differential enrichment medium design for the isolation and preliminary identification of C. neoformans

Contains 10% sheep blood; an enrichment agar useful for the isolation of pathogenic yeast and the dimorphic fungi in yeast forms from clinical specimens

Differential medium which aids in distinguishing Cryptococcus neoformans from Cryptococcus gotti

C. gotti colonies appear cobalt blue, indicating the assimilation of glycine whereas colonies of C. neoformans grow poorly and leave medium greenish yellow

recommended for the cultivation of chlamydospore-bearing C. albicans, with chlamydospore production further enhanced by addition of 1% Tween 80

NOT recommended for the production of chlamydospores, rather this formulation favors more luxuriant growth and improves pigment production used to differentiate T. rubrum which produces red pigment from T. mentagrophytes which does not
