The present study evaluates the efficiency of the following decontaminating agents for the multiresistant, locally circulating bacterium Pseudomonas aeruginosa: glutaraldehyde 2%--makes A and B-, glutaraldehyde-formaldehyde; povidone-iodine-makes A, B and C-; sodium hypochloride; chloroxylenol--makes A and B-; and lapire chloride. The 9027 ATCC strain was used as a standard. A modification of the method of Kelsey and Sykes (1) was used to evaluate decontaminating efficiency. Highly satisfactory results were obtained with glutaraldehide 2% A and B, glutaraldehyde-formaldehyde and sodium hypochlorite. The results for povidone-iodine A, B and C were satisfactory but were unsatisfactory for chloroxylenol and lapirium chloride.
