Document Summary
Mutualism: a relationship between individuals (usually from different species) where both individuals benefit (e. g. : clownfish and anemone) Microbiome: the totality of microbes in an environment; environment could be human body. Close to 200 different species of bacteria per person. Why is this mutualism and not parasitism? maturation of the immune system, energy balance, susceptibility to disease, and behaviour individuals need to consume 30% more food in order to get sufficient calories. Babies begin acquiring bacteria in utero, continue to gain bacteria over the first few years. In addition, the gut can be repopulated (for example, after an illness) by the appendix. Studies on mice indicate that in a sterile environment (ie in the absence of bacteria), Bacteria are incredibly useful; influence host metabolism, physiology and function, An enterotype is a classification of organisms based on the bacteriological. While there are overall similarities in the proportion of different bacterial species. Individuals lived in low density social groups.
