Anaerobic infections diagnosis is based on a number of factors. Primarily anaerobic infections diagnosis is based on the symptoms of the patient, on his medical history and of course on the infection location. One of the common features for anaerobic infections diagnosis is abscess drainage and foul-smelling infection. The foul smell is produced by anaerobic bacteria and is usually common for the latest stages of the disease. Other defining factors of the anaerobic infection are gas production and tissue necrosis on the infected place. In order to determine the kind of bacteria that cause the infection, it is possible to take a sample from the infected place with the help of a swab, a syringe or a needle. It is worthy of note that anaerobic infections rarely develop in laboratory cultures of pus or tissue samples. This can be explained by the fact that this kind of bacteria is easily destroyed by the oxygen. The medical history of the patient is of paramount importance for the accurate anaerobic infections diagnosis. The most susceptible group of people who can get an anaerobic infection is those who recently had dental work, blood vessel disease, injury, surgery or tumors. One of the ways to prove that the infection is caused by anaerobes is the failure of treatment with the help of antibiotics. The diagnosis can also be stated according to the type and location of the infection. In order to put the accurate anaerobic infections diagnosis it is possible to make blood tests and x rays. The former is done in order to see whether anaerobic bacteria are present in the blood of the patient, while the latter is made to define internal infections. Some anaerobic infections treatment may include hospitalization. It is necessary to apply the immediate antibiotic treatment. Thanks to the laboratory testing, it is possible to determine the bacteria that cause the current infection and the kind of antibiotics that can be the most efficient for curing the disease. There is no such an antibiotic which would be able to fight all kinds of anaerobic bacteria. Nevertheless, almost all anaerobes can be killed by such antibiotics as metronidazole, imipenem and chloramphenicol. It is also possible to use such antibiotics as clindamycin and cefoxitin. Almost every kind of abscess requires drainage or surgical removal. In order to remove the pus from the skin abscess, a syringe or needle can be used. This procedure is called "aspiration". It is necessary to numb the infected zone before the procedure. Another way to hold drainage for internal abscesses is ultrasound. This device applies sound waves in order to visualize the internal organs. This kind of the drainage can be performed in the doctor’s office. Doctors say that the best anaerobic infections prevention is maintaining general health and good hygiene. Nevertheless, anaerobic infections can occur in everyone. In order to achieve the complete recovery from anaerobic infections, it is necessary to combine appropriate antibiotic and surgery treatment. Bone destruction and severe tissue can be the result of uncontrolled and untreated infections. In order to repair them, plastic surgery is required. Serious cases can even be life-threatening.
