Question

QUESTION 25 Why might be of an advantage for a bacterium trying to colonize the bladder or the intestines to be motile? Flagella function as adhesions enabling bacteria to resist flushing and colonize the host mucosal epithellum. Flagella enable bacteria to swim away from phagocytes and resist enhanced attachment (opsonization) Flagella enable bacteria to stay in an area with plenty of nutrients and swim away from harmful chemicals like antibiotics Flagella enable bacteria to swim through the protective mucus so they can make contact with the host mucosal epithelium and subsequently attach and colonize the epithelium

Answer 1

Correct answer is option d

Explanation: Flagella in the bacteria which invades and resides in the intestine use flagella to thrive the mucous layers of the intestine. It also helps them to protect themselves and when they reach the epithelial cells, they attach themselves to the epithelial layer of mucous membrane and colonize there. So flagella is an important structure in the bacteria who colonize the small intestines and bladder.
