bacteria
/bækˈtɪəɹ.ɪ.ə/
This term carries a dual connotation, oscillating between the clinical sterility of a laboratory and the visceral fear of infection. While it often evokes images of illness or contamination in a medical context, it is equally used in biological and environmental contexts to describe essential life-sustaining processes, such as nitrogen fixation in soil or digestion in the gut. Grammatically, this word is the plural form of bacterium. In common usage, it is frequently treated as a collective mass noun, but in formal scientific writing, it remains strictly plural. Because it is the plural form, it requires a plural verb (e.g., bacteria are) rather than a singular one, though this distinction is often blurred in casual speech.
Technically the plural form of 'bacterium', though in common usage it is often treated as a collective mass noun when referring to an unspecified amount of germs.
