parasite
An organism that lives on or in a host and causes harm to the host.
virus
A microorganism smaller than the smallest bacterium that has no cellular structure and can cause infectious disease
eukaroyote
A cell that has a nucleus and organelles.
prokaryote
A single‐celled organism that lacks a membrane‐bound nucleus and specialized organelles.
microbiology
The study of extremely small organisms
anerobic
Lacking oxygen; referring to an organism, environment, or cellular process that lacks oxygen and may be poisoned by it.
aerobic
Containing oxygen; referring to an organism, environment, or cellular process that requires oxygen.
pathogen
A disease causing agent (usually bacteria or viruses).
toxin
Any substance said to accumulate in the body that is considered to be harmful or poisonous to the system.
heterotrophs
Organisms that are unable to construct their own food from inorganic sources, and therefore must consume other organisms or organic molecules from the outside environment. Function as consumers or decomposers in food chains.
autotrophs
An organism capable of synthesizing its own food from inorganic substances, using light or chemical energy. Green plants, algae, and certain bacteria are included in this classification.

Objects that can only be seen under magnification.

quorum sensing
A system of cell to cell communication that enables prokaryotes to sense and respond to density.
extremophile
A prokaryote, usually from the archea kingdom, which lives in an extreme environment. Extremophiles include methanogens, extreme halophiles, and extreme thermophiles.
asympotomatic
An organism which shows no outward signs of a pathogenic disease (but has been shown to have it in their blood, feces, or other secretions).
intermittent
Not continuous; happening at intervals.
nosocomial
hospital-acquired infection
ubiquitous

retrovirus
A virus that contains RNA as its genetic information, and uses reverse transcriptase to turn the RNA into DNA.
