The electrical thermometer was contaminated in the concentration of inoculum (10^5-10^7 CFU/0.1ml) made from the standard strains of St. epidermidis, S. marcescens, E. coli, K. pneumoniae, Ps. cepacia and C. albicans on serum. The pieces were disinfected for 5 to 20 minutes in the above disinfectants at 20℃.Then baterial kill time was examined in recovery medium after 3 to 7 days at ordinaly temperature. The result obtainied are as follows; 1) 1% Chlorhexidine gluconate, 0.5% ALkyl diaminoethyl glicine hydrochloride, 1% Glutaraldehyde and 0.1% Sodium hypochlorite disinfection efficiency them between 5 and 10 minites. 2) 50% Isopropyl alcohol and 0.2% Benzalkonium chloride disinfected them over 10 minutes.
