This photomicrograph depicted a number of Gram-positive, endospore-forming Bacillus anthracis bacteria. B. anthracis is the pathologic microorganism responsible for the disease 'anthrax', an acute infectious disease, which most commonly occurs in wild and domestic vertebrates (cattle, sheep, goats, camels, antelopes, and other herbivores), but it can also occur in humans when they are exposed to infected animals, or tissue from infected animals.
