[Characterization of Cryptococcus neoformans strains isolated from patients with acquired immunodeficiency syndrome (AIDS)].
Rev Latinoam Microbiol. 1995 Jul-Sep; 37(3):273-9.RL

Abstract

In Mexico cryptococosis ranks third in frequency among the mycoses ocurring as complications in AIDS patients. Neither the prevalence of the two varieties of C. neoformans in these patients nor the morphological and physiological changes suffered by these strains in AIDS patients are known. A total of 60 isolates were obtained from patients with AIDS from the Hospital de Infectología, Centro Médico "La Raza" IMSS. The identity of each isolate was established by: growth at 37 degrees C, colony and microscopic characteristics, urease and phenoloxidase activity, carbon sources assimilation. The canavanine glycine-bromothymol blue agar was used to distinguish C. neoformans var. neoformans and C. neoformans var. gattii. Pathogenicity in mice was also tested. Fifty one isolates of C. neoformans var. neoformans and nine of C. neoformans var. gattii were identified. All strains grew well at 37 degrees C, urease and phenoloxidase were positive, the morphology and the auxanographic profile were variable. C. neoformans var. neoformans was more virulent in mouse than C. neoformans var. gattii. This study has confirmed the presence of the two varieties of C. neoformans in Mexico with 85% prevalence of var. neoformans and 15% of var. gattii in AIDS patients. This frequency was higher than in reports from other countries.
