bakteerissa

Bakteerissa is the inessive singular form of the Finnish noun bakteeri, meaning “in a bacterium” or “inside a bacterium.” It is used to describe location or state within bacterial cells and is common in biology, microbiology, and related fields.

In practice, bakteerissa is used to discuss processes or features that occur inside a single bacterial cell. For example, sentences such as proteiinisynteesi tapahtuu bakteerissa (protein synthesis takes place inside a bacterium) or bakteerissa on kromosomi (a chromosome is inside a bacterium) illustrate its typical usage. When referring to more than one bacterium, the plural form bakteereissa is used. The inessive form helps distinguish intracellular contexts from extracellular ones, such as bakteerista (from a bacterium) or bakteeriin (into a bacterium).

Etymology and forms: The word bakteeri originates from the German Bakterie, which in turn derives from the Greek bakterion meaning “little staff” or “wand.” The inessive suffix -ssa/-ssä is attached to the stem bakteeri to form bakteerissa in the singular, and the plural form bakteereissa is used for multiple bacteria. Other related forms include bakteerin (genitive) and bakteeria (partitive).

Overall, bakteerissa is a standard factual term in Finnish for describing anything located inside a bacterial cell, with its plural bakteereissa used when referring to multiple bacteria.
