This photograph depicts the colonial morphology displayed by Gram-positive Bacillus megaterium bacteria, which was grown on a medium of sheep's blood agar (SBA), for a 24 hour time period, at a temperature of 37�C. The overall colonial morphology displayed by B. megaterium is very similar to that displayed by B. anthracis. See PHIL 12382, and 12383, for other views of this culture plate, and these bacterial colonies.
