ANTI BACTERIAL ACTIVITY OF SOME SELECTED DISINFECTANTS REGULARLY USED IN HOSPITALS

Abstract

The antibacterial activities of three commercial disinfectants: Dettol, Robert and Savlon against Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Salmonella typhi, Klebsiella spp. and Bacillus spp. were investigated. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were determined using the well technique of media diffusion method. The highest MIC of 1:10 against Pseudomonas aeruginosa by Roberts and the lowest MIC of 1:60 by Savlon against Staphylococcus aureus were observed. The highest minimum bactericidal concentration (MBC) of 1:10 against Escherichia coli and Pseudomonas aeruginosa was by Robert. All test organisms were susceptible to various dilution of Savlon used.
