The most in practice is the chemical method by using chemicals called disinfectants and these can be obtaining commercially. Some varieties of chemical disinfectants are available for killing some microorganism or at least preventing their multiplication, as such, this study was conducted on the evaluation of the bactericidal and Bacterostatic effect of some commercially produced disinfectants. Three disinfectants were used; Dettol (Reckitt Benkiser Pharmaceuticals Ltd), Trichlorophenol TCP (Neimeth int’l pharmaceuticals Plc) and Izal (Medreich PLC) on two bacterial isolates were studied. The test organisms used include Escherichia coli and Staphylococcus aureus. The various dilutions at which the disinfectants had bactericidal effect on the organisms were; Dettol (10-1: 0.163), TCP (10-1: 0.098, 10-2: 0.262, 10-3: 0.283) for E. coli. Dettol (10-1: 0.123, 10-2: 0.448), TCP (10-1: 0.002, 10-2: 0.004) for Staph. Aureus. But Izal exhibited Bacterostatic effect at dilutions; E. coli (10-1, 10-2, 10-3) showing 10-1: 1.4981, 10-2:1.557, and 10-3:1.686, while Staph. Aureus showed at 10-1:1.980, 10-2:1.998, and 10-3:1.998 respectively. It was observed that Dettol showed the highest bactericidal effect on the graving cells of E. coli and Staph. Aureus. Therefore, further work can be carried out on other available disinfectants with other resistant test organisms within the same study area for more information.
