Albicans strains with fluconazole. Method: A series of 16 strains C. albicans from the same body were induced to form pseudo-hyphae in RPMI 1640 medium and DMEM medium at 37 癈 for twenty-four hours respectively. The pseudo-hyphae and yeast were counted and the ratio between pseudo-hypha and total cells was calculated. C. albicans strains were induced to form pseudo-hyphae in RPMI 1640 medium for seven days by transferring twelve times. The genome DNAs of the hyphal-form of C. albicans was cleaved by two restriction enzymes EcoR I and Bgl II, the products were electrophored and photoed.
