Abstract
An electron microscopic comparison was made of five species ofCandida, namely:C. guilliermondii, C. krusei, C. parapsilosis, C. stellatoidea andC. tropicalis. The cell wall, plasma membrane and the cytoplasm with its organelles were described. The cell wall ofC. tropicalis was twice as thick as the cell wall in the other species.C. krusei appeared with distinct, rather elaborate wall sculpturing, a feature not pronounced in the other four species. A single nucleus with nucleolus appeared only in micrographs ofC. guilliermondii andC. krusei. At the same time, large central electron-luscent area (vacuole) appeared in the cells ofC. guilliermondii, C. parapsilosis andC. stellatoidea. The cytoplasm ofC. tropicalis was characterized by a granular appearance. Budding cells and pseudohyphae appeared similar to single cells in their general organelles. Such organelles in species studied were similar to these reported for other yeasts. These include: mitochondria, lipid granules, endoplasmic reticulum, ribosomes and vacuoles.
