Ultrastructural identification of extracellular material and appressoria in Candida albicans.
Ultrastructural studies of Candida albicans in its invasive form, obtained from oral lesions of patients with acute or chronic candidosis and of organisms grown on chorio-allantoic membrane of chick embryo have demonstrated a dense exudate-like material over the fungal cell wall surface. Such material appears to be involved in the digestion of the host cell wall and cell membrane, thereby assisting the organism to invade the host cell. During this invasion the apical tips of hyphae have a bulging appearance, resembling the appressoria of some plant pathogens.
