2. Morphology and Staining of Escherichia Coli: E. coli is Gram-negative straight rod, 1-3 µ x 0.4-0.7 µ, arranged singly or in pairs (Fig. 28.1). It is motile by peritrichous flagellae, though some strains are non-motile. Spores are not formed. Capsules and fimbriae are found in some strains.

Grow an E. coli quality control strain for 18-24 hours on a MacConkey agar at 35-37°C with ~5% CO2 (or in a candle-jar). Observe the MacConkey for specific colony morphology. As a sterility test, incubate an uninoculated plate for 48 hours at 35-37°C with ~5% CO2 (or in a candle-jar). Passing result: E. coli should appear as pink to red colonies. Describe features of colonies. See variations in colonial morphology among various species of bacteria. Bacteria grow on solid media as colonies.
