Medizone International, Inc. (OTC Bulletin Board: MZEI) announced today that every full scale test run completed thus far in its hospital room mock up facility has resulted in the total elimination of all bacteria present in the room. In this current phase of development, Medizone's scientific team will attempt to confirm, in a more realistic hospital setting, recent laboratory findings indicating extremely high antibacterial efficacy for its novel technology (6-7.2 log reductions) against the primary causative agents of hospital acquired infections (HAIs), sometimes referred to as "Super Bugs". Dr. Michael Shannon, Medizone's Director of Medical Affairs commented, "From the very onset, our new scaled up sterilization system performed magnificently. We have now completed multiple runs with very high concentrations of MRSA, VRE and E. coli samples that were distributed throughout the test room.
