Isolation and purification of chiamydospores of Candida albicans.
Two methods were investigated for their efficiency in isolating and purifying chlamydospores of Candida albicans. Chlamydospores were disconnected from pseudomycelial cells either enzymatically using beta-glucuronidase or mechanically by ultrasonic treatment. Free chlamydospores were separated from other cell material by sucrose gradient centrifugation. The resulting preparations were inspected by light-microscopy and electron-microscopy. Both methods yielded preparations with a level of over 90% chlamydospore cells. Ultrasonic treatment caused little change to the ultrastructure of the chlamydospores, whereas the enzyme treatment profoundly affected the cell wall. It is concluded that ultrasonic treatment is an efficient method for obtaining pure preparations of chlamydospores.
