Pulsed-field gel electrophoresis (PFGE) patterns of SfiI restriction endonuclease analysis of genomic DNA (REAG-S) with dendrogram for Candida albicans isolates. A genetic similarity percentage is shown above the dendrogram. Patient identification (Pt ID), sample site (Source), and number of days after admission to the intensive care unit that the strain was isolated (Day) are included along each PFGE lane. Saccharomyces cerevisiae DNA concatemers and λ DNA ladder were used as size markers. Sizes are measured in kilobases (Kb). C. albicans strain SC5314 (ATCC MYA-2876) was used as the control strain. Abbreviations: SG, supragingival dental plaque; TS, tracheal secretion; BL, bronchoalveolar lavage.
