Question
Chapter 25.3, Problem 2R
Summary Introduction
To review:
The problem from a health standpoint in case all bacteria from a human gut are eliminated.
Introduction:
The microbes are found in various kinds of surroundings. Among them, some bacteria are helpful and some are harmful. The human gut mucosa contains a huge number of bacteria, which are an important component of gut ecosystem. These form a part of the normal microbiota of the body. This normal microbiota provides various benefits to the body, such as microbial antagonism, nutritional benefits, and others.

Students have asked these similar questions
What role does the human microfauna play in protecting humans against pathogens? (At this point in the class, you should be able to provide a detailed list of activities bacteria species perform in and on our body that protect us from pathogens.)
Many pathogenic bacteria are unable to make some of the metabolic compounds needed for growth and have instead evolved enzymes that enable the bacteria to actually invade human body cells. What do these bacteria expect to accomplish by this practice?
We are outnumbered by the bacteria in our colon. Why don't they typically make us
sick?
a) They don't have enough food resources to thrive.
Ob) The pH of the colon is too acidic.
c) They do not prefer the environment of our intestine.
d) The competition between microbes limits their pathogenicity (microbial
antagonism).
