A sampling of ''Bacillus anthracis''—Anthrax
A 'biological agent' is an
infectious disease or
toxin that can be used in
bioterrorism or
biological warfare. There are more than 1200 different kinds of biological agents.
Biological agents include
prions,
microorganisms (
viruses,
bacteria and
fungi) and some unicellular and multicellular
eukaryotes (for example
parasites) and their associated
toxins. They have the ability to adversely affect human
health in a variety of ways, ranging from
allergic reactions that are usually relatively mild, 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.
Examples of biological agents are
anthrax,
avian influenza,
botulism,
foodborne illness,
hantavirus,
Legionnaires' disease,
molds and
fungi,
pneumonic plague,
smallpox,
tularemia, and
viral hemorrhagic fevers (VHFs).
