This image depicts a view of a Petri dish culture plate, which contained a growth medium of sheep blood agar (SBA), and which had been inoculated with Bacillus anthracis, and B. cereus bacteria. Note the differing colonial morphology produced by the two different bacteria. B. cereus bacteria on the left, produced larger, smoother, more mucoid colonies, which were surrounded by a zone of hemolysis, while colonies on the right, produced by B. anthracis, were rougher, smaller, and not surrounded by an hemolytic activity.
