Biological Agents
Biological agents are living organisms or toxins that have the potential to cause harm to humans, animals, or plants. These agents can include bacteria, viruses, fungi, parasites, and toxins produced by living organisms. They can be used for both beneficial purposes, such as in medicine or agriculture, or for harmful purposes, such as in bioterrorism. Biological agents can spread through various means, including inhalation, ingestion, or contact with contaminated surfaces.
