BACILLUS
Bacteria in the genus Bacillus are large Gram-positive rods. They are shown here in a Gram stain at 1000 X magnification. When Bacillus replicates, the two daughter cells often stay close together forming chains. Pathogenic species in the genus Bacillus include Bacillus anthracis, the cause of anthrax, and Bacillus cereus , a cause of food poisoning. It is not possible to distinguish different genera of Bacillus from one another by a Gram stain. Biochemical tests must be run for complete identification. Note that the genus name Bacillus is capitalized and in italics (or underlined). Members of this genus are always Gram-positive and must have other specific characteristics (aerobic, spore formers, etc.) to be in this genus. In contrast, the word "bacillus", spelled with a lower case "b" and not in italics, is used to indicate any rod-shaped bacteria, no matter what its other characteristics might be.
