n. pl. bac·te·ri·a (-tîr′ē-ə)
1. Any of various prokaryotic microorganisms of the domain Bacteria that may be free-living, saprophytic, commensal, or pathogenic and that vary widely in terms of morphology, oxygen tolerance, nutritional and temperature requirements, and motility. Also called eubacterium.
2. Any of the prokaryotic organisms, such as an archaeon. Not in scientific use.

bac·te·ri·um

(băk-tîr′ē-əm)
Plural bacteria
Any of a large group of one-celled organisms that lack a cell nucleus, reproduce by fission or by forming spores, and in some cases cause disease. They are found in all living things and in all of the Earth's environments, and usually live off other organisms. Bacteria make up most of the kingdom of prokaryotes.

bacterial adjective
Usage It is important to remember that bacteria is the plural of bacterium, and that saying a bacteria is incorrect. It is correct to say The soil sample contains millions of bacteria, and Tetanus is caused by a bacterium.

bacterium

(pl. bacteria) A very small, single-celled, prokaryotic organism.
