Mm. Nishikawa et al., USE OF D-PROLINE ASSIMILATION AND CGB MEDIUM FOR SCREENING BRAZILIAN CRYPTOCOCCUS-NEOFORMANS ISOLATES, Journal of medical and veterinary mycology, 34(5), 1996, pp. 365-366
D-proline assimilation and CCB tests were performed on 233 Cryptococcu
s neoformans isolates from Brazil. The results disclosed a high sensit
ivity, D-proline 99.13% and CGB 99.57%, for screening of the varieties
. D-proline assimilation test revealed two false negative results for
5.1% of 39 strains of var. gattii, and no false positive results were
observed in 194 strains of var. neoformans. No false results and only
one doubtful result were found on the CGB medium.
