Anaerobic infections description says that the infections are rather common; they may be rather dangerous and even cause death. The scope of anaerobic bacteria diseases include such diseases as abscess formation and necrotic gangrenous tissue, black discoloration of exudates that is usually caused by Bacteroides melanimogenicus, endocarditis or bacteraemia, foul smelling discharge, pneumonia and peritonitis, free gas contained in the tissue and "sulphur granules" caused by Actinomyces spp.
Anaerobic infections description includes the following facts. Anaerobic infections are pretty common; they may be rather serious and even life-threatening. Anaerobes are considered to be the predominant part of bacterial flora characteristic for mucous membranes and normal human skin. Anaerobic infections description notes that the infections are rather difficult to isolate from the sites that are infected and they can be often forecasted. In order to isolate the infections special methods of specimen collection, cultivation and transportation are required. Anaerobic infections description tells that anaerobic infections are rather difficult to cure due to a number of reasons. First of all, the growth of the organisms is very slow. The second reason is the polymicrobial nature of the infections and at last the constant increasing of the infections resistance to the antimicrobial agents.
There are several risk factors of anaerobic infections that are singled out by anaerobic infections description. One of the most common risks is the poor tissue necrosis and blood supply that may be caused by trauma, malignancy, oedema, colitis, foreign body, surgery, shock and vascular disease. Among other risks it is possible to name diabetes mellitus, immunocompromise, previous infections with facultative or anaerobic organisms, splenectomy, collagen vascular disease.
Speaking about clinical features of anaerobic bacteria diseases, it is possible to point out to the following. There are some clinical conditions that are predisposed to anaerobic infections. Among other clinical features it is possible to single out abscess formation and necrotic gangrenous tissue, black discoloration of exudates that is usually caused by Bacteroides melanimogenicus, endocarditis or bacteraemia, foul smelling discharge, pneumonia and peritonitis, free gas caontained in the tissue and "sulphur granules" caused by Actinomyces spp.
The diagnosis of an anaerobic infection is based on symptoms, on the medical history of the patient and, of course, on the location of the infection.
As for the microbiological picture of anaerobic infections, it is possible to make the following conclusions. It is of paramount importance to be very careful while collecting, transporting, and processing specimen. This should be done to get the accurate picture of anaerobic infections.
It is worthy of note that the results can become misleading and the misinterpretations can be caused by minimal contamination of normal flora to the specimen. It can be explained by the fact that there are huge numbers of anaerobes on mucous membranes and skin. Thus the best anaerobes for culture must be obtained without any contamination. They can be obtained from such sources as blood, urine that is collected by suprapubbic bladder aspiration, deep wound aspirates, lung aspirate, transtracheal aspirate, abscess contents (pus is more preferable than a swab), and others. It is necessary that the specimen should be quickly transported to the laboratory, preferably by means of anaerobic transporter.
