Abstract

The present invention relates to a system for detecting microbial contamination of a liquid specimen comprising a device for concentrating micro-organisms from a liquid specimen, having (i) a hyperbaric chamber, (ii) a filter housing comprising a liquid-permeable bed of an adsorbent material and adapted for being fluidly connected to said hyperbaric chamber, and (iii) a means for pressurizing said hyperbaric chamber, said system further comprising a kit for detection of micro-organisms adsorbed to said adsorbent material, wherein said kit is based on enzymatic detection using chromogenic and/or fluorescent substrate analogues.
