A small, nonliving particle that invades and then reproduces inside a living cell

Single-celled organisms that lack a nucleus, prokaryotes

Eukaryotic organisms that have cell walls, use spores to reproduce, and are heterotrophs that feed by absorbing foo

An organism that lives on or in a host and causes harm to the host

a disorder of structure or function in a human, animal, or plant, especially one that produces specific signs or symptoms or that affects a specific location and is not simply a direct result of physical injury

A chemical that can kill bacteria without harming a person’s cells. These only work on bacteria

Short for microorganism. A tiny living thing (like bacteria, fungi, or protists) or a virus that is too small to be seen without a microscope. While some are helpful, others cause disease

An organism (like a human, animal, or plant) that provides a home and a source of energy for a parasite or a virus

A substance introduced into the body to stimulate the production of chemicals that destroy specific viruses, bacteria, or other disease-causing organisms

An organism that transmits a disease. The organism does not cause the disease itself, but spreads infection by conveying pathogens from one host to another

An organism that is infected with a pathogen and can spread it to other organisms but does not show any outward signs of the infection

An organism that causes disease Infectious Disease

Noninfectious Disease

A disease that is not caused by a pathogen

An outbreak of a disease that affects many people in an area

An epidemic that spreads over a large area, or throughout the world

A sudden increase in the occurrences of a specific disease in a particular time and place (like a single town or a school)

Your body's complex defense network. It uses specialized white blood cells to identify, attack, and destroy pathogens (germs) that enter the body

A "marker" or protein found on the surface of a pathogen. It acts like a nametag that tells your immune system, "I don't belong here!" Antibody

Antibiotic Resistance

This happens when bacteria change or mutate so that the drugs (antibiotics) designed to kill them no longer work. It is a major problem caused by overusing or misusing medicine

A type of medication used specifically to treat viral infections (like the flu). Unlike antibiotics, which kill bacteria, antivirals usually work by stopping the virus from copying itself inside your cells
