Infectious Agents (for Humans, Plants, and Animals)
Infectious agent means a living organism (such as a bacteria, fungi, virus), too small to be seen with the naked eye but visible under a microscope and capable of causing a disease. This includes agents that are potentially infectious to humans, animals, and plants, or potentially disruptive to the environment. The safe handling of any infectious agents depends on the individual characteristics of the agent itself and the biosafety level of containment at which the organism can be safely manipulated.
