This study utilizes the high-performance liquid chromatography technique in combination with the new micropreparative solution isoelectric focusing fractionation on non-woven fabric strip for the characterization and differentiation of biofilm-positive and biofilm-negative forms of Candida parapsilosis sensu stricto on the basis of the changes in the composition of their cell-surface. Treatment of yeasts by boiling in distilled water relased surface substances from yeasts cells. Consequently, the optimized procedure has been used for fast identification of the highly pathogenic biofilm-positive Candida parapsilosis group in real clinical material - sonicate from vascular catheters. Moreover, the capillary isoelectric focusing was used as supporting and control technique. Obtained results suggest that this new method can be used to distinguish between biofilm-positive and negative forms of Candida parapsilosis sensu stricto.
