Staphylococcus epidermal - Gram-positivebacterium, one of the 33 known species belonging to the genus Staphylococcus. It is part of the normal flora of the skin (commensal) of man. The bacterium can also be found on mucous membranes and in animals. In addition, this is probably the most common form found in laboratory studies.
Although staphylococcus epidermal, as a rule, notpathogen, in patients with a weakened immune system there is a risk of infection. This infection can be out-of-hospital, but it poses a great danger for clinic patients. These are very hardy microorganisms, which are immobile, Gram-positive cocci, located in the form of grape clusters. The microorganism forms white cohesive colonies about 1-2 millimeters in diameter after incubation overnight.
Staphylococcus epidermis causes infections,associated with intravascular devices (prosthetic heart valves, shunts, etc.), but also often found in prosthetic joints, catheters. Catheter infections can lead to serious inflammation and secretion of pus. In these cases, urination is extremely painful. Septicemia and endocarditis are also diseases that can be associated with this type of staphylococcus. Their symptoms range from fever, headache and fatigue to anorexia and dyspnea. Sepsis is especially common as a result of infection of newborns, especially with very low birth weight. Infective endocarditis develops as a result of damage to the heart valves or endocardium.
Since staphylococcus epidermis is part of thenormal microflora of a person, then he developed resistance to many antibiotics, such as "Methicillin", "Novobiotsin", "Clindamycin", and "Penicillin."
As a result, "Vancomycin" or "Rifampicin" is used to treat the infection.
The risk of infection is associated with:
- Low immunity due to cancer, chemotherapy, AIDS, serious illnesses (especially in the elderly), low birth weight (newborns);
- congenital heart disease or vascular diseases;
- internal dentures: artificial heart valves, artificial joint, shunts, etc .;
- Vascular or urinary catheters, peritoneal dialysis;
- skin diseases, injuries, burns;
- abnormalities of the gastrointestinal mucosa, as well as the intake of antibiotics that kill normal intestinal bacteria.
Note! Infection can also develop in the outer layers of the skin, usually in open wounds, where epidermal staphylococcus enters. On the face are also possible such types of infection, which, as a rule, is characterized by inflammation and purulent discharge. Talk with your doctor or health care provider if you have any suspicions that it is staphylococcus.
