| Various organisms have been characterized by molecular methods, including fungi of the genus Cryptococcus. The purposes of this study were: to determine the discriminatory potential of the RAPD (Random Amplified Polymorphic DNA) primers, the pattern of similarity of the Cryptococcus species, and discuss their useful application in epidemiological studies. We analyzed 10 isolates of each specie/group: C. albidus, C. laurentii complex, C. neoformans var. grubii, all from environmental source, and two ATCC strains, C. neoformans var. grubii ATCC 90112, and C. neoformans var. neoformans ATCC 28957 by RAPD-PCR using the primers CAV1, CAV2, ZAP19, ZAP20, OPB11 and SEQ6. The primers showed a good discriminatory power, revealing important differences between them... |
