Pseudomonas aeruginosa, a ubiquitous Gram-negative bacillus characterized by its greenish color and sweetish smell, is at the origin of potentially severe forms of dermatosis, such as ecthyma gangrenosum which marks immunosuppression or reveals blood-poisoning, especially in children. It frequently colonizes chronic wounds and serious burns, and spongiotic or acantholytic dermatosis, especially when severe or localized in skinfolds. It requires special care because of its high resistance to antibiotics and antiseptics. It can also involve folliculitis favored by water sports or a nail disorder (chloronychia).
