Week 15 Vocab Definitions

Pathogen A gene or infectious agent that causes disease or illness to its host Passive immunity Short term immunity that develops after the organism is exposed to a pathogen Active immunity Longer lasting immunity that body develops in response to an infection.

Antigen Part of a pathogen that stimulates an immune response in the body Antibody Proteins produced by B Cells that react with and disable antigens Vector An organism that transmits disease (virus, bacteria, ticks)

Antiviral A drug that destroys or prevents a virus from reproducing. Antibiotics An agent that stops the growth of bacteria Virus An infectious agent that must reproduce inside a host cell. Vaccine Dead or inactivated pathogens which cause the development of antibodies
