Cellulite infection: what is it?

The cellulitis is an infection by bacteria that spread in and under the skin, it attacks the tissues "soft" as the skin itself, the subcutaneous tissue and underlying fat. It also relates to cellular spaces between the organs in the body: for example the mediastinum (between the skin, lungs and heart). It often occurs from a wound or a button badly treated, and especially medical and surgical interventions dental poorly managed. The names we give vary depending on the locations of the infection.

What are the risks and health issues of skin infection?

Risks are uncontrollable extension of infection: locally in the skin tissue (gangrene) and organs (meningitis), or throughout the body via the bloodstream (septicemia). The death is not uncommon despite advances in intensive care: a patient in seven septicemia (investment figures published in 2005).

The reasons for this high mortality are manifold. Bacteria have a specific toxicity (such as meningitis) and more resistant to antibiotics (such as staph). Then, the frail or temporarily weakened many are elderly, children, chronically ill patients already infected (AIDS, malaria) ...

The cellulitis is not contagious distance since it is an infection trapped in the body under the skin, but when the skin deteriorates bacteria show in the open air, ready to infect the unwary. L hygiene and antibacterial protection therefore apply with rigor: handwashing and everything that comes into contact, wear gloves and a mask, clothing and personal items reserved and treated separately.

What are the mechanisms of cutaneous cellulitis?

Bacteria proliferate everywhere in our environment, as well as on and in our bodies. This parasitism more or less advantageous to the host that we are fits to the nose, ears, throat, umbilicus, beard and hair all in general. This is the reason for the wide and careful shaving of the skin during surgery.

There is a risk of cellulitis infection when the barrier between the outside world and ourselves is broken (skin and mucous membranes, but also trachea and intestine). This occurs during a cut, wound, works dentistry, surgery or an animal bite. The inoculated differ depending on the circumstances leading to various forms of cellulite.

Streptococci and staphylococci are the most frequently involved. The introduction of a streptococcus pyogenes causes erysipelas said: the most common cutaneous cellulitis. Staphylococci cause malignant staphylococcal face very serious. A very aggressive strain of group A streptococcus necrotizing cellulitis causes (or necrotizing fasciitis) with tissue destruction.

The agent of tetanus (Clostridium tetani) enjoys a simple skin lesion to cause a fatal disease in the absence of rapid resuscitation. Other clostridia cause gangrene.

In many parts of the world (among the neighboring countries, especially those of the Maghreb, and more rarely), the germ of anthrax (Bacillus anthracis) is always present as spores in the soil. Used as a biological weapon, this organism causes a characteristic skin lesion (an anthrax anthrax) and / or highly fatal systemic infection.
