[The identification of Cryptococcus neoformans var. neoformans in Cuban clinical isolates]

50 strains of Cryptococcus neoformans of clinical origin were studied by using the canavanine-glycine-bromothymol blue (CGB) medium. 56% of the strains were isolated from AIDS patients, and 16% belonged to patients with kidney transplantation. 90% of the samples were obtained from the samples of cerebrospinal fluid, which corresponded to the classical form of presentation of cryptococcosis. All the strains were identified as C. neoformans var. neoformans, coinciding with previous reports made in Cuba. Knowing the varieties of C. neoformans, inferences can be drawn on the epidemiology, clinics and response to the treatment of cryptococcosis.
