||Electron micrographs prepared by Prof. James Cronshaw suggest that for S. aureus grown in similar conditions the cell wall thickness is about 18 nm and the average cell radius is about 440 nm. Salton ("The bacterial cell wall" Elsevier, Amsterdam, 1964) quotes a range of 10-20nm as typical for the cell wall thickness of S. aureus deduced from electron micrographs.
