Aims: The internal unit and ICU of hospitals are a suitable environment forgrowing of bacteria such as Staphylococcus epidermidis, Pseudomonas andAcinetobacters. The aim of this study was to evaluate the efficacy of usingdisinfectants on bacterial remove in Isfahan City, Iran, hospitals.Instrument & Methods: This descriptive study was performed in Isfahan City,Iran, hospitals in 2015. 200 samples were taken from random locations of thehospitals. Sampling was carried out at the end of the business day and beforedisinfecting the surfaces with sterile cotton swabs moistened by sterile saline.After identification of bacteria, the numbers of bacterial colonies were countedbefore disinfection in 1ml (CFU/ml).Findings: The highest isolates were detected from emergency unit beforedisinfection included Pseudomonas aeruginosa, Staphylococcus spp., Escherichiacoli, Proteus spp., Klebsiella spp., Acinetobacter spp., and Enterobacter spp. 255cases of bacteria were found at 27 positive samples. The most common isolatedbacteria after disinfection were Staphylococcus epidermidis (76 cases), E. coli(42 cases) and Micrococcus luteus (39 cases).Conclusion: The disinfecting process of Isfahan Hospitals is effective inremoving bacterial infections.
