Anywhere in the world

Bacteria live anywhere, even in the most extreme environments where no other form of life could survive. They can be found in the ocean depths, in the desert, in the hot waters of volcanic springs, inside rocks, in the frosty soil of the permafrost and even in environments so acidic they could destroy any other form of life. Many bacterial species live inside or on other organisms as symbionts or parasites. Symbiosis is an association between two or more species, which benefits each component; conversely, in parasitism only one of the members benefits from the association (the parasite), while the other (the host) is damaged by it.
Our body too is inhabited by very many species of bacteria. Every square centimetre of our skin is populated by thousands of bacterial cells that reproduce endlessly. Our gastrointestinal apparatus contains up to 500 different bacterial species, mostly living in the colon.
