Resumen

Objetive: Evaluate  an  Ozone  Generating  System  (OGS)  through  of  the microorganisms count and identi?cated in the air of the sanitary environments of the National Institute of Health (INS) from Peru. The study: These were exposed to OGS for 1 min per m2, air samples were collected at volumes of 200L, 500L and 1000L by impaction, pre and post exposure to OGS, cultures were obtained on Plate Count Agar (PCA) and Oxytetracycline Glucose Agar (OGA) grown at 35°C±2°C for 48 hours and 25°C ± 2°C for 5 days. Findings: A decrease in the count of fungi after exposure to OGS, the di?erence being statistically signi?cant for the volumes of 200L (p=0.047) and 1000 L (p<0.005); Aspergillus spp. species were identi?ed in most cultures, in bacteria no signi?cant di?erence was observed. Conclusions: The OGS is a method that inhibits the growth of most fungi in sanitary environments.
