Quimiotipagem do Cryptococcus neoformans. Revisão da literatura. Novos dados epidemiológicos sobre a criptococose. Nossa experiência com o emprego do meio de C.G.B. no estudo daquela levedura

Abstract: O presente trabalho, além da revisão da literatura sobre quimiotipagem do C. neoformans, com novos dados sobre a epidemiologia da criptococose, teve por finalidade principal a caracterização das duas variedades desta levedura em pacientes com neurocriptococose, HIV + e HIV -. As variedades neoformans e gattii estão hoje bem definidas bioquimicamente, com o emprego do meio C.G.B., proposto por KWON-CHUNG et al. (1982) 24. O isolamento do C. neoformans var. gattii das flores e folhas do Eucalyptus camaldulensis … Show more

“…FRANZOT et al 30 proposed the reclassification of A-serotype into a new species: grubii. Several epidemiological inquiries show the heterogeneous distribution of these subtypes of cryptococcosis agents in several countries, verifying, consequently, the hypothesis of a correlation between etiologic agent variety and geographic regions according to MELO et al 49 . In Brazil, the pioneer study of LACAZ & RODRIGUES 40 showed that the majority (64%) of 25 biological samples belonged to the neoformans variety with the A-serotype prevailing followed by B and D. Predominance of this serotype into our clinical setting was therefore, confirmed by other authors both with biological and environmental samples 10,11,12,32,52,53 .…”

“…In this study, the species characterization of isolates from HIV-infected patients living in the city of Ribeirão Preto , state of São Paulo , Brazil, was performed by analyses of fungal growth in CGB-Agar and molecular characterization. There was a 100% agreement between these two methods for the species identification, showing that the CGB biochemical test is reliable and offers advantages because it is not expensive, is little laborious and provides fast results 17 , 21 , 35 , 36 .…”
