Microbiology Review

A branch of biology dealing especially with microscopic forms of life (as bacteria, protozoans, viruses, and fungi).

Any microscopic organism. Mainly viruses, bacteria, protists, some fungi, and even some tiny multi-cellular organisms.

Diseases that are caused by infecting organisms; they can be passed from person to person

Microbes that cause disease

single-celled spherical or spiral or rod-shaped prokaryotic organisms lacking chlorophyll that reproduce asexually by fission

Non living particles composed of nucleic acid (DNA or RNA) and a protein coat. They reproduce by invading healthy cells and using the enzymes and organelles of the healthy cell. This usually results in the death of the host cell.

A kingdom made up of non photosynthetic, eukaryotic organisms that have no means of movement, reproduce by using spores, and get food by breaking down substances in their surroundings and absorbing the nutrients. Most are multicellular and reproduce both sexually and asexually.

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

Plant like protists that grow in soil, on trees and on the bodies of turtles and frogs; smallest of all green plants

Drugs that block the growth and reproduction of bacteria

helps fight viruses

injection of a weakened or mild form of a pathogen to produce immunity

the communication of disease by direct or indirect contact

Animal that transports a pathogen to a human

animal-like protists that are single-celled consumers
