title: A rapid pigmentation test for identification of Cryptococcus neoformans.
abstract: A rapid pigmentation test for identification of Cryptococcus neoformans is described. The method is based on the formation of a characteristic, mouse-grey to violaceous-black pigment when shake cultures of C. neoformans in a phosphate-buffered, l-DOPA - ferric citrate medium are incubated at 37 C for one hour.
