Introduction: Disinfection is a process which pathogenic microorganisms on non-living surfaces are destroyed, so choose of appropriate disinfectant and standard disinfection methods can be effective in reducing nosocomial infections. The aim of this study was to evaluate the efficacy of common disinfectants on microorganisms isolated from different parts of Shahid Sadughi accidents burns hospital in Yazd in 2011. Methods: In this cross sectional descriptive-analytic study the sampling method has done randomly. In this study 240 samples were collected from 30 different parts of surfaces of 4 different parts of hospital. 30 samples before and 30 samples after disinfection were taken for each disinfectant. The samples were cultured on blood agar and EMB culture media in the Microbiology laboratory of Medical Sciences University. Disinfectants of Deconex 50 AF, Descoscid, Epimax SC and Silvosep have investigated. Data were analyzed using T-test. Results: The average of bacteria isolated from 4 parts of the burn unit of the hospital, before disinfection by Deconex 50 AF, Descoscid, Epimax SC and Silvosep were 33737.49, 25784,18, 35085.65, 30504.77, respectively and after disinfection were, 14.3, 18569.42, 2.15 and 5.63, respectively that all of these disinfectants, have shown a significant difference (p<0.05) in decreasing of microorganisms. More commonly isolated microorganisms were Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus epidermice, Enterobacter species, Escherichia coli and yeast. Conclusion: The results showed that these disinfectants were effective against isolated microorganisms and also the number average of bacteria have shown a significant difference before and after disinfection and the most effective disinfectants was Epimax SC.
