Bacteria are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a domain of prokaryotic microorganisms. Bacteria were among the first life forms to appear on Earth and are present in most habitats. They are vital in many stages of the nutrient cycle by recycling nutrients. The study of bacteria is known as bacteriology, a branch of microbiology. Humans and most other animals carry millions of bacteria; most bacteria in and on the body are harmless or rendered so by the immune system, and many are beneficial. Several species are pathogenic and cause infectious diseases. Antibiotics are used to treat bacterial infections and also in farming, making antibiotic resistance a growing problem. Bacterial cells do not contain a nucleus and rarely harbour membrane-bound organelles. Their scientific classification changed after the 1990s discovery that prokaryotes consist of two groups of organisms that evolved from a common ancestor. (Full article...)
