Abstract
- The extraordinary ability of Cryptococcus species to cause disease has focused the attention of scientists on finding ways to improve their identification methods. In this study, PCR-REA, manual methods (morphological and biochemical characteristics), API 20C and VITEK 2 were used to test identify a total of 30 Cryptococcus spp. from human and veterinary sources. PCR-REA was performed using the capsular region as amplification target followed by restriction with the enzymes AgeI, BsmFI and HpaII. PCR-REA identified the strains as C. neoformans var. grubii (n=19) and C. gattii (n=8). There was no significant difference between the API 20C AUX and VITEK 2 when compared to manual methods for the identification of Cryptococcus spp. However, none of these non-manual methods were able to detect C. gattii samples. PCR-REA showed a greater level of concordance with the manual method, besides being faster and more sensitive than the other methods. Therefore, it is indicated for routine identification of Cryptococcus spp. strains.<br /> (Copyright © 2011 Elsevier B.V. All rights reserved.)
