Thinking back to yesterday's reading, what type of ecological relationship is it? What are the bacteria doing for us? How do they avoid being killed off by our immune system? Gut Bacteria Reading

The relationship between gut bacteria and we the host is a mutualistic relationship. This is a form of relationship where both we and the bacteria benefit from the bacteria living in our gut.

They help us in our digestion process to break down some food particles into their basic units, some of which we would not be able to do without them. They also help to keep the gut’s surface intact, provide vitamins, and fight off other harmful bacteria.

Bacteria use immunity genes to neutralize toxins and protect themselves against been destroyed by our immune system by copying our immune resistance code, and using this code to make their outer membrane.
