Dental Clinic staffs are exposed to the risk of cross infection due to patient s blood, saliva and contaminated dental instruments. This study was designed to evaluate the performance of AOS Zero Germ (AOS Co. Ltd) effervescent labware wash tablet. A total of six types carbapenemase-producing Gram negative bacteria (KPC-2-producing Klebsiella pneumoniae , KPC-3-producing K. pneumoniae, NDM-1-producing K. pneumoniae , VIM-2-producing Enterobacter cloacae , VIM-2-producing Pseudomonas aeruginosa , OXA-23-producing Acinetobacter baumannii ), methicillin-resistant Staphylococcus aureus , vancomycin-resistant Enterococcus faecium were prepared in this study. All the isolates were exposed to the distilled water prepared with AOS Zero Germ. After the exposure the mixture of bacteria and AOS Zero Germ was inoculated onto MacConkey agar plate or blood agar plate and cultured at 37℃. All isolates were killed immediately of an exposure to AOS Zero Germ. It may be recommended that AOS Zero Germ can be used as an effective labware washer for clinical laboratory and an intermediate-level disinfectant for hospital infection control.
