anaerobic bacteria organisms that can survive and grow in an atmosphere of almost no oxygen. Anaerobic bacteria can be divided based on their relation to oxygen: obligate, facultative anaerobic or aerotolerant. They can be found in various environments ranging from soil and water in the body of humans and other animals. Many anaerobic bacteria are usually in the body, indeed, the human gut, anaerobic bacteria than aerobic bacteria 1000 1. Clostridium species almost exclusively anaerobic, spore-forming Gram-positive bacteria. Clostridia spores can withstand a long time in adverse environmental conditions. When conditions are favorable, spores germinate and then are bacteria that can grow and multiply. Many clostridia are capable of producing very powerful toxins when they multiply. They are responsible for some of the most serious human infections: tetanus, gas gangrene and botulism. Clostridium species are found in soil, water and in the intestines of humans and animals. Actinomyces species straight or slightly curved gram-positive bacteria, which can range from strattera short rods in length, branching rods. These anaerobic bacteria are usually found in the mouth, upper respiratory tract and to a lesser extent, the gastrointestinal tract. They are not particularly dangerous types of bacteria and usually cause infection when there is a breach on the surface of the mouth and upper respiratory tract infections (opportunistic infections). Bacteroides species are spore-forming Gram-negative bacillus and is considered one of the most important anaerobic bacteria because they are involved in many infectious processes and their resistance to antibiotics. Bacteroides most common types of anaerobic bacteria isolated from soft tissues and bacteremia. The bacteria produce many virulence factors such as capsule, endotoxin and various enzymes that cause tissue destruction. Bacteroides species are among the most common bacteria found in human excrement. Propionibacterium species pleomorfnye gram-positive bacteria, which may appear oval, bacillary or bulavopodibni. Some may be branching or forked also. This group of aerotolerant anaerobic bacteria that can grow and multiply in the presence of oxygen. These anaerobic bacteria are usually found on the skin and are associated with the inflammatory process in acne (acne Propionibacterium). They can also cause endocarditis and bacteremia, but is generally considered pollutants and non-pathogen. "Color Koneman in Atlas and textbook of diagnostic microbiology," Elmer Koneman, MD, 2006
