I took it to mean a bacterial colony that was part of a human, which would be true. But I suppose that way of meaning would also be true because the first way is true. 🤔

Well, there are plenty of bacteria who form colonies, though I’m not sure if any do it as part of a stage of life. I’m not aware of any bacteria that have stages of life at all, like how insects have larval, pupal, etc. But bacteria do experience stages as a colony: https://en.wikipedia.org/wiki/Bacterial_growth
