<![CDATA[The toilet is one of the facilities provided to meet the needs of users with various backgrounds of different hygiene behavior, so that they can be a source of bacterial transmission, one of which is Escherichia coli (E.coli), which is resistant to producing Extended-Spectrum Beta-Lactamase (ESBL). E.coli producing ESBL can cause infection of various diseases, to overcome this, preventive measures are taken to reduce the level of risk transmission through the use of toilet seat sanitizers. This study aims to determine the effectiveness of toilet seat sanitizer against E.coli producing ESBL. This research is a descriptive observational laboratory study using a toilet seat sanitizer with an active substance of 50%-Benzalkonium Chloride and Ethyl Alcohol 96% against E.coli producing ESBL American Type Culture Collection (ATCC) 35218. The phenol coefficient test was used to measure the effectiveness of the toilet seat sanitizer was compared with phenol, Minimum Inhibitory Concentration (MIC) and Minimal Bactericidal Concentration (MBC) were tested using the tube method. This study showed that the coefficient of toilet seat sanitizer effective against E.coli producing ESBL was 4,5. MIC active substance toilet seat sanitizer is effective at a concentration of 0,3125%, and MBC at a concentration of 0,625%. The author concludes that the results of the MIC and MBC prove that a toilet seat sanitizer active substances 50%-Benzalkonium Chloride and Ethyl Alcohol 96% is effective as a disinfectant against E.coli producing ESBL ATCC 35218.]]>
