Abstract


This study is aimed at evaluating the efficacy of some disinfectant and antiseptics on bacteria isolated from environmental and human samples. A 2-fold serial dilution was prepared for each of the disinfectant/antiseptics: 2-1, 2-2, 2-3 and seeded onto Mueller Hinton agar using the Modified Kirby-Bauer agar well diffusion technique. Phenol Coefficient was also carried on each of the germicides. The result obtained from agar well diffusion method of antimicrobialsensitivity test revealed the efficacies of four disinfectants and four antiseptics and it was observed that almost all the test bacteria were very sensitive to the undiluted concentration of nearly all the disinfectants and antiseptics. Almost all the agents had Phenol Coefficient above 1.0 indicating their effectiveness. This study discovered most of the disinfectants andantiseptics to be effective when not diluted and dettol was proved to be the most effective
