This photograph depicts the colonial morphology displayed by Gram-positive Bacillus cereus 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. Worthy of note, is the hemolytic reaction caused by these bacteria, as evidenced by the faded, hazy coloration surrounding these colonies. It is within this region of faded red color, that the red blood cells in the SBA medium had been lysed, or destroyed by chemical by-products produced by these organisms, thereby, liberating their intracellular hemoglobin.
