The purpose

Leg ulcers are defined as wounds lasting for more than a month. They would receive 0.2% of the population of Western countries. In Europe, the cost per episode of leg ulcers is estimated at 6650 euros (10 000 euros for a foot ulcer). The cost of treatment of wounds would be 2 to 4% of the health budget. Infection is the most common complication of chronic wounds: in most cases, it results in delayed healing, at most, it can result in amputation or serious general complications Bacterial contamination of ulcers is constant. Over time for over 25 years, various studies have shown about relatively identical results. The bacteria are present in over 90% of the etiology of venous leg ulcers. These bacteria are divided into four most common classes: Staphylococcus aureus, Enterococcus, Streptococcus, Pseudomonas. The bacterial ecology changes over time. Indeed Staphylococcus aureus appears first, while the Pseudomonas is associated with ulcers lasting for several months. Anaerobic more difficult to find, are found in 30% of cases Cohabitation between leg ulcers and bacteria often without clinical consequence: These are the stages of infection and colonization. The infection is related to the proliferation of bacteria and their invasion into the skin, by increasing their virulence (virulence genes acquisition). The increase in the number of bacteria and the multiplicity of bacterial genera are one reason for the increased virulence of bacteria. When bacteria proliferate, because the host defenses are inadequate, or because there is a vascular disease which promotes the proliferation, clinical signs appear
