Transmission electron micrographs of ultrathin sections of Candida
albicans fixed with DMSO:
A: A whole yeast cell grown at 37°C, showing long, regularly radiating fibrils;
B: Section of a yeast cell grown at 25°C, showing details of cell envelope ultrastructure;
C: Schematic diagram of a typical cell wall derived from Shepherd showing the various
layers:
plasma membrane (PM), zone of mannoprotein (M1), glucan-chitin (GC), glucan (G),
mannoprotein (M2) and outer fibrillar layer (F).

Transmission electron micrographs of ultrathin sections of Candida
albicans fixed with DMSO:
A: An image of a 25°C-grown cell revealing intracellular organelles;
B: Brush-like fibrillar structure on the outermost surface of a C. albicans cell
grown at 37°C.
Note the interconnections of the long fibrils between two cells (arrow);
C: A cell grown at 37°C showing distinct, long individual fibrils.

Transmission electron micrographs of ultrathin sections of Candida albicans
cells
fixed with DMSO, showing the effect of different growth temperatures and DTT treatment
on cell wall ultrastructure:
A: A cell of C. albicans grown at 25°C showing short, blunt fibrils;
B: A cell of C. albicans grown at 37°C showing long, tightly packed and
distinct fibrils;
C: A C. albicans cell grown at 45°C with short, aggregated fibrils;
D: A C. albicans cell grown at 37°C and treated with DTT showing fibril
loss.

Candida albicans display surface variations consistent with observed intergeneric
coaggregation.
