Depiction of the human body and bacteria that predominate. A microbiota is the ecological community of commensal, symbiotic and pathogenic microorganisms that literally share our body space.Joshua Lederberg coined the term, emphasising the importance of microorganisms inhabiting the human body in health and disease.he symbiotic relationship between animal host and microbiota has a significant impact on shaping the immune system. The immune system is able to recognize the types of bacteria that are harmful to the host and combats them, while allowing the helpful bacteria to carry out their functions.
Gut microbiota (formerly called gut flora) is the name given today to the microbe population living in our intestine. Our gut microbiota contains tens of trillions of microorganisms, including at least 1000 different species of known bacteria with more than 3 million genes (150 times more than human genes). Microbiota can, in total, weigh up to 2 kg.
