This image depicted numbers of Bacillus anthracis bacterial colonies, which had been allowed to grow on sheeps blood agar (SBA) for a 24 hour period. In this particular view youll note the appearance of what is termed a "plaque" (arrowhead), which represents an area where the bacteria had been lysed, or destroyed by the application of a localized amount of gamma phage-containing solution. Highly specific to B. anthracis, these gamma phage viruses, i.e., bacteriophages, attacked the B. anthracis bacteria, subsequently leaving this circular plaque devoid of bacterial organisms. The specificity of these gamma phages to B. anthracis makes this a positive test for the presence of this bacterium.Created: 2009

This image depicted numbers of Bacillus anthracis bacterial colonies, which had been allowed to grow on sheeps blood agar (SBA) for a 24 hour period. Note the classical appearance exhibited in the colonial morphology including a ground-glass, non-pigmented texture with accompanying comma projections from some of the individual rough-edged colonies. In this particular view, youll note that a tenacity test had been performed using an iinoculating loop, which proved positive for B. anthracis, causing the colony to stand up like beaten egg white.Created: 2009

Anthrax most commonly occurs in wild and domestic mammalian species (cattle, sheep, goats, camels, antelopes, and other herbivores), but it can also occur in humans when they are exposed to infected animals or to tissue from infected animals or when anthrax spores are used as a bioterrorist weapon.Created: 2009
