Anaerobic bacteria can be divided into strict anaerobes that can not grow in the presence of more than 0.5% oxygen and moderate anaerobic bacteria that are able of growing between 2 and 8% oxygen. [1] Anaerobic bacteria usually do not possess catalase, but some can generate superoxide dismutase which protects them from oxygen.
Eikenella corrodens is a Gram-negative facultative anaerobic bacillus that can cause severe invasive disease in humans. [1] It was first identified by M. Eiken in 1958, who called it Bacteroides corrodens. [2]
Bacteroides fragilis is an anaerobic, Gram-negative, pleomorphic to rod-shaped bacterium. It is part of the normal microbiota of the human colon and is generally commensal, [1] [2] but can cause infection if displaced into the bloodstream or surrounding tissue following surgery, disease, or trauma.

Pseudomonas aeruginosa in Petri dish. Pseudomonas aeruginosa is a common encapsulated, Gram-negative, aerobic–facultatively anaerobic, rod-shaped bacterium that can cause disease in plants and animals, including humans.
Fusobacterium is a genus of obligate anaerobic, Gram-negative, [2] non-sporeforming bacteria [3] belonging to Gracilicutes. Individual cells are slender, rod-shaped bacilli with pointed ends. [4] [5] Fusobacterium was discovered in 1900 by Courmont and Cade and is common in the flora of humans. [6] [7]
Anaerobic gram-positive cocci are frequently isolated from anaerobically infected bones and joints., they accounted for 40% of anaerobic isolates of osteomyelitis caused by anaerobic bacteria and 20% of anaerobic isolates of arthritis caused by anaerobic bacteria. P magnus and P prevotii are the predominant bone and joint isolates.
Other symptoms of tetanus may include fever, sweating, headache, trouble swallowing, high blood pressure, and a fast heart rate. The onset of symptoms is typically 3 to 21 days following infection. Recovery may take months; about 10% of cases prove to be fatal. [1] C. tetani is commonly found in soil, saliva, dust, and manure. The bacteria ...
Little is known about the natural factors that control phage infection and replication within the bacteria. [ 43 ] The spores require warm temperatures, a protein source, an anaerobic environment, and moisture in order to become active and produce toxin.
