Abstract

In ecology, an ecosystem refers to the combination of a community of living creatures and their environment (the biotope). Our intestine contains numerous ecosystems. The human gut microbiota is made of just over 1,000 species of bacteria. Each of us is host to more than 200, and each individual has his or her own unique microbiota. Despite a high biodiversity, they serve a very similar role from one healthy person to the next. The total sum of genes within our gut microorganisms known as metagenome has a genetic potential 100 times higher than that of human genome. They control a whole range of physiological and sometimes pathological functions i.e. balanced ecosystem that constantly regulates itself. The fragile balance may be upset if the microbiota comes under attack and the term dysbiosis was introduced and the imbalance was associated with harmful consequences for the host. After many research into gut microbiota, it becomes much easier to explain â�?�?Gut microbiota: Who are you, where are you and what are you doingâ�?.
