[Morphogenesis of Candida albicans in human serum. Mycelial and pseudomycelial tubes observed in 250 strains].

The morphogenesis of Candida albicans, more peculiarly the mycelial and pseudomycelial tubes production, was investigated during 24 hours in human serum: on 250 strains at 37 degrees C, and on 24 strains at 25 degrees C. The characteristic of the tubes, their first apparition and maximum production time are reported. The yeast influence (origin, saprophytic or parasitic state, serotype, maximum temperature for growth of the strain) on the tubes production is discussed.
