Anaerobes are bacteria that are capable of growth or the absence of oxygen (referred to as facultative anaerobes) or that require absolutely no oxygen (they are called obligate anaerobes). Among the oxygen-free environment in which these bacteria can grow deep wounds and tissues in the body. Growth in these niches can produce infections. Examples of gas gangrene infection (which is caused by Streptococcus pyogenes) and botulism (Clostridium botulinum due). Other anaerobic bacteria that often causes clinical infections are representatives of the genus
Peptostreptococcus and Bacteroides fragile. There are a number of different types of anaerobic bacteria. Two basic means of differentiation of these types is their reaction to Gram and in form. Reid
Clostridium consists of gram-positive bacillary bacteria that form spores. Gram-positive rods, which do not form spores includes delivery
Actinomyces, Bifidobacterium
,
Eubacterium, Propionibacterium
and
Lactobacillus. Gram-positive bacteria with a spherical shape includes delivery
Peptostreptococcus, Streptococcus
and staphylococcus. Bacilliform bacteria that stain gram include
Bacteroides, Campylobacter
and
Fusobacterium. Finally, gram-negative bacteria presented a spherical genus Veillonella >>. << Word anaerobic means "life without air." In the human body, regions that may be deprived of oxygen includes interior >> << dental board, which grows on the surface of the teeth and gums, gastrointestinal tract, and even buy strattera on the skin surface. Typically, anaerobic bacteria that grow in these conditions are benign and can even help the body work. Most bacteria in the body anaerobes. However, if access to the main fabric is provided by trauma or surgery, bacteria can penetrate into new territory and establish infection. These bacteria are described as opportunistic microorganisms. That is, given the opportunity and appropriate conditions, they can cause infection. Typically, anaerobic bacteria cause 5 to 10% of clinical infections. Anaerobic infections typically have several common features. The infection is usually accompanied by fetid gas or manure. Infections are usually located near the membranes, especially the mucous membranes, as the infection usually begins with the invasion of the region bounded by a membrane. Anaerobic infections are usually associated with destruction of tissue, or because of bacterial digestion or destructive >> << enzymes produced by bacteria. This type of tissue damage called necrosis of tissues. Tissue damage and often includes a gas or liquid. There are several sites in the body that are prone to infection of anaerobic bacteria. Infections in the abdomen can cause inflammation
process, known as appendicitis. Mild infections may cause pneumonia
, infection of the mucous membrane lung (pleura) or narrowing of small air pipe, known as the bronchi (bronchiectasis). In women, pelvic infection can inflame the mucous membrane of the uterus (endometritis). Mouth infections can include root canals or gums (gingivitis). Infections of the central nervous system can lead to brain and spinal cord infection. Infections of the skin through bites and other pathways, causing open sores on the skin and tissue destruction. Example is that massive and potentially lethal tissue degradation, known as necrotizing fascitis, and which caused the group B-hemolytic
Streptococcus. Finally, blood poisoning (bacteremia) may be a prelude to infection of the heart (endocarditis). Diagnosis of anaerobic infection is usually based on symptoms, site of infection and if infection is seen as the appearance and odor of the infected area. Most of the bacteria responsible for infections susceptible to one or more antibiotics
. Treatment may be continued, however, because bacteria often grow slowly and with antibiotics rely on
growth of bacteria to their deadly effect. In the case of infections that pose tissue destruction, removal of diseased tissue is an option to prevent the spread of infection. Amputation of limbs is a common defense against necrotizing fascitis, an infection that is inside the tissue (and thus protected from antibiotics and host immune response) and is exceptional in that it can quickly spread.
