Toxin: any poisonous substance from plants, animals, microbes, or made in a lab, including engineered products and closely related chemical forms. Delivery system: any device, equipment, or other means made to spread or release a biological agent, toxin, or a vector. Vector: a living organism or molecule, including lab-made ones, that can carry a biological agent or toxin to a host.
