Abstract

VALERIO, Henrique Maia; WEIKERT-OLIVEIRA, Rita de Cássia Botelho  and  RESENDE, Maria Aparecida de. Differentiation of Candida species obtained from nosocomial candidemia using RAPD-PCR technique. Rev. Soc. Bras. Med. Trop. [online]. 2006, vol.39, n.2, pp. 174-178. ISSN 0037-8682.  http://dx.doi.org/10.1590/S0037-86822006000200008.

Thirteen strains of the genus Candida were isolated from catheter, urine and surgical wounds from individual patients of the Santa Casa de Misericórdia, Belo Horizonte, MG, Brazil. Ten strains were characterized as Candida albicans, two as Candida glabrata, and one as Candida parapsilosis. Isolates were evaluated for molecular relatedness by random amplified polymorphic DNA technique using 15 primers. The analysis of the genomic DNA obtained revealed a low intraspecific polymorphism and did not allow for the differentiation between strains of the same species obtained from distinct clinical sources (catheter, urine and surgical wounds). The RAPD profiles generated were able to differentiate among the species of Candida albicans, Candida parapsilosis and Candida glabrata strains isolated in this study.

Keywords : Candida spp; Random amplified polymorphic DNA; Polymorphism; Nosocomial infection.
