[Pathogenicity and saprophytism of the "Candida" (author's transl)]

Many cases of bacterial turnover saprophyatism and pathogenicity are known in infectious clinic; these are variously explained on mutational basis or wandering conditions of the rapports host-agent. Transformation of Candida from saprophpyte to pathogenic organism seems, up to date, to be hardly explainable, and would represent an interesting research field.
