Pseudomonas aerugiosa is as impretant causative pathogen of most of nosocomical infection in intensive care units (ICUs). It is the second most frequently isolated organism which causes ventilator associated pneumonia. It also happens to be the fourth most frequent pathogen causing septicemia, urinary tract infections and surgical wound infections. There has been a change in the pattern of transmission of P. aeruginosa in the past dacade. Stdies demonstrate that approximately 50-92% of nosocomical P. aeruginosa acquisitions may result from transmission theough tap water. The recent studies have confirmed the transmission of P. aeruginosa theough tap water. The studies sduggest that the infection rates can be significantly lowered by eliminating colonized tap water or by intereupting teansmission chains feom water sites.
