[Use of a method of lipid extraction from Candida albicans cell walls blastospores. Ultrastructural implications concerning their localization and parietal microfibril organization].
A chemical method for lipid extraction has been applied to Candida albicans blastospores previously to their examination by transmission electron microscopy. The results led to the concept of a superficial location of lipids bounded to the peptidopolysaccharidic matrix of the cell wall. This lipid extraction also allowed us to describe cell wall microfibrillar structures. Two types of microfibrills have been particularly identified: microfibrils of approximately 50 A in diameter, involved in a network of the cell wall intermediate layers and supposed to correspond to beta 1-3 glucans; fibrillar structures of 120 A in diameter, similar to chitin microfibrils, observed in the bud scar septum.
