Thymidine-dependent small-colony variants (SCV) of Staphylococcus aureus exhibited unusual colony morphology with “fried-egg” or pinpoint white colonies on agar plates and pleomorphic cocci as determined by Gram staining. Electron microscopy revealed enlarged cocci with incomplete or multiple cross walls consistent with impaired cell separation.

Potassium tellurite is reduced to form grey-black shiny colonies. Typical colonies of S.aureus on this medium are 1-1.5mm diameter, with an opaque halo surrounded by a 2-5 mm zone of clearing. The halo is a result of lipase activity and the clearing zone is due to proteolytic action (1,3,6,7,9,10,12).

However, the small size of staphylococcal cells has impaired analysis of changes in morphology during the cell cycle. Here we use super-resolution microscopy and determine that S. aureus cells are not.

Cultural Characteristics of Escherichia Coli: It is an aerobe and a facultative anaerobe. The optimum growth temperature is 37°C. On Nutrient agar, colonies are large, thick, greyish white, moist, smooth, opaque or translucent discs. The smooth (s) form seen in fresh isolation is easily emulsified in saline, whereas the rough (R) form often auto agglutinates in saline.
