 Infection control of MFW. All chronic wounds contain bacteria. Kingsley2003 state that the change in numbers of bacteria and the bodys response as a continuum, rating from contamination to infectionKingsley, 2003. Contamination is mean that the bacteria present on the wound surface but are not proliferating and have no clinic effect; colonised imply bacteria have proliferated, but there is no host reaction; critical colonisation occurs where the bodys local host response starts to be initiated, but there are no systemic sign of infection; Infection is point in time when the bacteria have multiplying and invaded deeper tissues, healing is impaired and produced a systemic host reactionJacqui.
