Sоme pаthоgens mаke fimbriаe tо attach to cells lining the gut of their host. However, it would be a waste of resources to make fimbriae when not in the gut. In some bacteria, fimbrial gene transcription is initiated when the cell detects leucine, which would likely be abundant in a nutrient‐rich environment like a gut.
