Epidemiology of Candida infection. I. Use of killer system for typing of Candida albicans strains.

A killer system was used for epidemiological differentiating of 350 Candida albicans strains isolated from human sources of different anatomical and geographical origin. By using 9 killer strains from genera: Hansenula, Pichia, Torulopsis, Saccharomyces it was possible to differentiate 87 killer types. Our findings showed differences in the occurrence of the types according to the origin of the strains. The killer system proves to be valid for the differentiation of strains within the Candida species for epidemiological purposes.
