Conversation

Did you hear about the water quality tests they did around here?

Yeah, I heard they found some coliform bacteria in a few places.

That's kind of alarming; we should probably avoid drinking tap water for now.

Definitely, it's better to stick with bottled water until they sort it out.

Root Explanation

Coliform is formed from "coli" (from Latin "colis", meaning of the colon) and "form" (from Latin "forma", meaning shape or form). The term refers to bacteria that are found in the colon, thus indicating their origin and shape.

Memory Tip

Think of 'coli' relating to the colon, and 'form' meaning shape — coliform bacteria are those that have a shape associated with the colon.
