[Comparison of in vitro activity of six disinfectants on bacteria from contamination in hemodialysis water].

The bactericidal and sporicidal activities of six disinfectants were compared in vitro by determination minimal bactericidal concentrations from AFNOR standards for antiseptics and disinfectants. These disinfectants were tested against seventeen bacterial strains and two suspensions of spores including reference strains and wild strains from water of hospital environment. The compound with peracetic acid, ACETOPER 200, is the only disinfectant with the two activities against all strains at 21 degrees C +/- 1 degree C in short length of time. Furthermore except for Serratia liquefaciens that is remarkably resistant to STERLANE, no significant differences of susceptibility to disinfectants appear between wild bacterial strains and reference strains.
