Anaerobic Bacteria Open Access Journals
Anaerobic bacteria are a part of normal flora of human skin and mucosal membranes. The site of anaerobic
infection is usually the location of normal colonization. The spectrum of infections ranges from local abscesses to life-threatening infections. Anaerobic bacteria differ from aerobic bacteria in their oxygen requirement. Oxygen is toxic to anaerobes which can be explained by the absence of enzymes in the anaerobes of catalase, superoxide dismutase, and peroxidase enzymes. Anaerobes are fastidious organisms and are difficult to grow if proper collection and culture methods are not used. The diagnosis requires clinical suspicion and proper microbiological identification. The obligate anaerobes can further be subdivided into 2 types based on a percentage of oxygen that can prove toxic. Strict obligate anaerobes which will not survive if there is more than half a percent oxygen in the environment, while moderate obligate anaerobes can still grow in a 2% to 8% oxygen environment.
Anaerobic microorganisms don't reproduce within the sight of oxygen; be that as it may, they display generous contrasts in deadly impact of oxygen. When all is said in done, anaerobic living beings discovered only as expected vegetation are severe anaerobes (i.e., kick the bucket inside minutes in <0.5% oxygen), while those of clinical criticalness are to some degree aerotolerant (i.e., endure 2% to 8% oxygen). Severe anaerobes don't develop in 10% CO2 in air; microaerophilic microbes can develop in 10% CO2 in air or under oxygen consuming or anaerobic conditions, and facultative creatures can develop in the nearness or nonappearance of air.
