title: Molecular typing of clinical Candida strains using random amplified polymorphic DNA and contour-clamped homogenous electric fields electrophoresis.
abstract: OBJECTIVE
  This report describes an investigation into the genetic profiles of 38 Candida albicans and 19 Candida glabrata strains collected from a dental hospital of Monastir (Tunisia) and the Laboratory of Parasitology, Farhat Hached Hospital of Sousse (Tunisia), using two typing methods: random amplified polymorphic DNA (RAPD) and contour-clamped homogenous electric fields (CHEF).
  
  
  RESULTS
  The two methods (RAPD and CHEF electrophoresis) were able to identify clonal-related isolates from different patients. RAPD method using two primers (CA1 and CA2) exhibited the highest discriminatory power by discriminating 22 genotypes for C. albicans with CA1 oligonucleotides and 19 genotypes with CA2 primer. For C. glabrata, 17 genotypes were obtained when both primers CA1 and CA2 were combined. The CHEF karyotyping of C. albicans has discriminated only 17 different karyotypes.
  
  
  CONCLUSIONS
  The genotype of each isolate and genotypic difference among C. albicans and C. glabrata isolates were patient specific and not associated with the site of infection, geographic origin or date of isolation.
  
  
  CONCLUSIONS
  Identification of relatedness between Candida species using molecular approaches with high discriminatory power is important in determining adequate measures for interruption of transmission of this yeast.
