The present invention relates to a novel antimicrobial absorbent dressing incorporating a silver ion source which exhibits excellent antimicrobial activity against biofilm-organized bacteria. According to the invention, this dressing comprises: a- an absorbent nonwoven pad formed of two-component superabsorbent fibers bonded to each other by needling, and one of the components gels in contact with the exudates while the other component does not gel on contact with the exudates, or a mixture of two-component superabsorbent fibers, one component of which gels on contact with the exudates while the other component does not gel on contact with exudates and non-absorbent thermoling fibers, all the fibers being thermolated, b-one layer contact with the wound covering the face of the compress facing the wound； said contact layer comprising openings allowing the passage of wound exudates and having a grammage of between 100 and 350 g / m2 and being formed of an elastomeric composition containing hydrocolloids, in a proportion of between 2 and 20% by weight weight of said composition； said dressing comprising a quantity of silver ions greater than or equal to 0.6% and less than or equal to 1.2%, expressed by weight relative to the total weight of the dressing； La présente invention est relative à un nouveau pansement absorbant antimicrobien, incorporant une source d'ions argent, qui présente une excellente activité antimicrobienne contre les bactéries organisées en biofilm. Selon invention, ce pansement comprend : a- une compresse non tissée absorbante formée soit de fibres superabsorbantes bicomposants liées entre elles par aiguilletage, et dont un des composants gélifie au contact des exsudats tandis que l'autre composant ne gélifie pas au contact des exsudats, soit d'un mélange de fibres superabsorbantes bicomposants dont un des composants gélifie au contact des exsudats tandis que l'autre composant ne gélifie pas au contact des exsudats et de f
