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
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?
If coliform bacteria are native to human colons, why the big concern over coliform contamination?
Why has it been so difficult to associate human disease, orhealth, with changes in the gut microbial community?
