Bacteria are microbes found on the skin, in the nose, mouth, and especially in the gut. We acquire these bacteria during birth and the first years of life, and they live with us throughout our lives. The human microbiota is involved in healthy growth, in protecting the body from invaders, in helping digestion, and in regulating moods Bacteria that live within the human body are called Normal flora. They are helpful bacteria. Where they are present? What are the different types of bacteria.. The human microbiome is the aggregate of all microbiota that reside on or within human tissues and biofluids along with the corresponding anatomical sites in which they reside, including the skin, mammary glands, seminal fluid, uterus, ovarian follicles, lung, saliva, oral mucosa, conjunctiva, biliary tract, and gastrointestinal tract.Types of human microbiota include bacteria, archaea, fungi. The human body contains trillions of microorganisms — outnumbering human cells by 10 to 1. Because of their small size, however, microorganisms make up only about 1 to 3 percent of the body's mass (in a 200-pound adult, that's 2 to 6 pounds of bacteria), but play a vital role in human health Overall mass of bacteria in the body. ~0.2 (~0.3% of overall body weight) kg.

Bacteria and other microorganisms in the body make up the human microbiota. The majority is located in the gastrointestinal tract, but all surfaces in contact with the environment are colonized, that is, the skin, upper respiratory tract and genital tract. The microbiota co-exist with the human host and have many important functions, as. Within the human gastrointestinal microbiota exists a complex ecosystem of approximately 300 to 500 bacterial species, comprising nearly 2 million genes (the microbiome). 1 Indeed, the number of bacteria within the gut is approximately 10 times that of all of the cells in the human body, and the collective bacterial genome is vastly greater. Probiotics-- often called friendly or good bacteria-- are live, lactic-acid producing microorganisms that are similar to those found in the human digestive tract. These beneficial bacteria are associated with numerous health benefits. They are also widely used in clinical nutrition and complementary alternative medicine Per the updated estimates, the human body contains ~4×10 13 bacteria. Our bodies contain ~3×10 13 human cells. However, per the Weizmann Institute paper, about 90% of those cells are enucleated blood cells. Thus the vast majority of cells in an adult do not contain nuclear or mitochondrial DNA. Ergo, the total number of human cells that.
