The image below shows Escherichia coli on Gram staining. This site needs JavaScript to work properly. Most E coli strains are nonpigmented. MacConkey agar is selective for Gram-negative organisms and helps to differentiate lactose fermenting gram-negative rods from non-lactose fermenting gram-negative rods. Fastidious organisms, such as streptococci, do not grow well on ordinary growth media. Both microorganisms grow on this selective media because they are gram-negative non-fastidious rods.
