Abstract: in this lab we tested the effectiveness of different antibiotics, antiseptics, and disinfectants against different bacterial strains (escherichia coli, bacillus cereus, micrococcus luteus, and serratia marcescens. At present, it is difficult to translate these laboratory findings to actual clinical use, and some studies have demonstrated that antibiotic-resistant bacteria are not significantly more resistant to the lethal (or bactericidal) effects of antiseptic and disinfectants than are antibiotic-sensitive strains (11, 88, 89, 319.
