Effect of Least Concentration of Hydrogen Peroxide (H2o2) Against Airborne Fungi

Airborne indoor fungi were assessed during the winter season using open plate technique, SDA were used for isolation of fungi. The air samples were collected during December -February from different locations in the hospital. Air samples were taken in three months period during pre and post cleaning of the hospital wards. In all of the tested places a significant increase of mould spores was observed in pre cleaning but in post cleaning with 0.3% Hydrogen peroxide, there was no fungal growth and majority of the plates were sterile. Six genera of fungi, mainly members of the genus Aspergillus spp, Mucor spp, Rhizopus spp, Fusarium spp, Penicillium spp and Candida spp were isolated. Aspergillus spp showed highest growth numbers. This study could make a contribution not only using the least concentration of disinfectant in the hospital personnel but also in detection of preventive measure to be taken against hospital infections.
