Influence of serum on antibacterial activity of disinfectants and evaluation of disinfectant testing methods, ie, phenol coefficient method and minimum inhibitory concentration method, were studied. Changes in the effect of various disinfectants such as phenol, saponated cresol solution, povidone-iodine, benzethonium chloride and chlorhexidine were determined against various strains of S. aureus, S. typhi, E. co1i, Klebsiella, Serratia, P. aeruginosa, P. maltophilia, P. cepacia and A. xylosoxidans. 1) Antibacterial activity of phenol, cresol and povidone-iodine reduced very slightly after serum is added, but that of serum-added benzethonium chloride and chlorhexidine decreased remarkably. 2) The bactericidal effect of serum-added disinfectants 1 hour after contact with bacteria reduced by 25 to 50% 24 hours after. 3) The antibacterial effect of disinfectants determined by MIC method showed a considerable difference between the effect by phenol coefficient method. So concentration and bactericidal time should be taken into consideration in the evaluation of disinfectant testing methods.
