Anaerobic infections are infections that are caused by bacteria called anaerobes that are not able to develop in the presence of oxygen. Anaerobic infections can occur in those places where there is little or no oxygen. The most frequent places for the development of anaerobic infections are internal organs, deep tissues and deep wounds. These infections are usually characterized by the destruction of tissues, foul-smelling pus and abscess formation. The word "anaerobic" signifies "life without air". The bacteria are often found on the skin, in the mouth, in vagina, in gastrointestinal tract. Among the most frequent diseases caused by this kind of bacteria are botulism, tetanus and gas gangrene. It is worthy of note that almost all dental conditions are caused by anaerobic bacteria as well.
As a rule, anaerobic infections cause some kind of disease when there is an injury or damage of the natural barrier, such as intestinal wall, gums and skin. In general, it is the immune system that is responsible for fighting different invading bacteria. Nevertheless, it is not always able to cope with all of them, thus letting them develop and damage the organism. One of the factors stimulating the growth of anaerobic bacteria is necrosis, that is tissue destruction, or not sufficient blood supply which is not able to provide the necessary amount of the oxygen. Among the factors causing the lack in oxygen are surgery, shock, vessel disease and injury.
Anaerobic infections causes and symptoms can be evident almost in every part of the body. For instance, anaerobic infections causes and symptoms can be found in the throat, mouth and head. The infections can easily occur in gums in the form of gingivitis, jaw, sinuses, ears, root canals and tonsils. It is also possible to discover throat infection symptoms. As for lung infection symptoms, they include the symptoms of pneumonia, empyema, lung abscesses and dilated bronchi of the lungs called bronchiectasis.
Anaerobic infections can be intraabdominal. In this case, they are characterized with abscess formation, appendicitis and peritonitis. Female genital tract is also prone to the development of anaerobic infections causes and symptoms. In this part of the body the infections show themselves in the form of pelvic abscesses, endometritis, pelvic inflammation disease and various pelvic infections that usually appear after some kind of surgery, abortion or childbirth. Soft tissue and skin are also common places for the development of anaerobic bacteria. They are a common phenomenon for gangrene, diabetic skin ulcers and destructive infection characteristic for tissues and deep skin. Anaerobic infections causes and symptoms may even occur in the central nervous system. They can become apparent in the form of spinal and brain cord abscesses. Anaerobic infections can easily develop in the bloodstream of sick patients.
It is worthy of note that there are a great number of anaerobic bacteria. Nevertheless, the most dangerous bacteria are so called "mixed infections". It signifies the mixture of various bacteria.
