BACKGROUND AND OBJECTIVEA basic principle of disinfection is to use effective and safe disinfection solutions with minimal damage to equipment and staff. While none of the disinfectants are appropriate for all the various infectious agents and secondly, given that the choice of type of disinfectant is important in medical environments, there is a need for research to determine the effects of different disinfectants.MATERIALS AND METHODSIn this research, sampling took place at ۳۰ different surfaces in a specialized medical diagnostic laboratory. Afterwards, all surfaces were disinfected with the commercial disinfectant solution Bacillol BODE and the sampling was redone. From samples collected before and after disinfection, microbial cultures were prepared on Mueller Hinton agar and colony counts were recorded using a colony counter. The data obtained were analyzed with the SPSS software and P<۰.۰۵ was considered a significant level.RESULTS AND DISCUSSIONTHE results showed that in all the studied surfaces, after disinfection with Bacillol BODE solution, the number of colonies reached zero on average, which was significantly less than before disinfection (P <۰.۰۵).CONCLUSIONBacillol BODE solution has a high ability to disinfect laboratory surfaces and was able to destroy all microbial colonies. Therefore, it can be used in both therapeutic and laboratory settings.
