[Experimental test of the bacteriostatic and bactericidal effect of six disinfectants for Pseudomonas aeruginosa].

Minimal inhibitory concentration (MIC) and minimal bacteriocidal concentration (MBC) of six chosen disinfectants against pseudomonas aeruginosa were tested by the tubular liquid double dilution method. Results showed that 0.06% Chang Kou Jing and 1.5% Supertime are fairly good disinfectants against pseudomonas aeruginosa in infected wound surfaces, postoperative wound dressing, disinfection of surgeons' arms and hands before operation, sterilization of instruments and scrub medical workers' hands after contact with infected patients. The MIC and MBC of the former were 7.5 micrograms/ml and 30.0 micrograms/ml separately, while those of the latter were 11.7 micrograms/ml and 93 micrograms/ml respectively.
