A sampling of Bacillus anthracis—Anthrax

A biological agent is a bacterium, virus, prion, fungus, or biological toxin that can be used in bioterrorism or biological warfare. More than 1200 different kinds of biological agents have been described and studied to date. Applying a slightly broader definition, some eukaryotes (for example parasites) and their associated toxins can be considered as biological agents.

Biological agents have the ability to adversely affect human health in a variety of ways, ranging from relatively mild allergic reactions to serious medical conditions, even death. These organisms are ubiquitous in the natural environment; they are found in water, soil, plants, and animals. Because many biological agents reproduce rapidly and require minimal resources for preservation, they are a potential danger in a wide variety of occupational settings.
