Failure of dry mist of hydrogen peroxide 5% to kill Mycobacterium tuberculosis

SummaryA dry mist of hydrogen peroxide (DMHP; Sterinis), was used to test for surface decontamination of air-dried samples of Mycobacterium tuberculosis, 3 × 105 cfu/mL in open plastic trays. No significant decontamination effect of DMHP could be observed after three ordinary cycles with hydrogen peroxide or after doubling the effect with six repeated cycles.
