Gut bacteria have a number of important functions such as breaking down food, manufacturing vitamins and training our immune system. Two of the most important roles have to do with immune system protection and metabolism. Understanding how specific bacteria produce disease has been tied to knowledge of virulence properties, which allow the bacteria to function as monoetiological agents. If capsule is too thick it is known as slime. The primary function of most endospores is to ensure the survival of a bacterium through periods of environmental stress. The makeup of the normal flora may be influenced by various factors, including genetics, age, sex, stress, nutrition and diet of the individual.
