ABSTRACT
To determine the ozone inactivation kinetic of different Gram positive and Gram negative multiple antibiotics resistant bacterial strains from clinical isolation (CI), that resists too high concentration of chlorine, and compare them with reference strains was our objective. Microorganism’s concentration was from 105 to 106 ufc/mL, and chlorine and ozone concentrations were between 0.5 - 4 mg/L, and 0.36 - 2 mg/L respectively. Gram-positive multiple antibiotic resistant strains are the most resistant bacteria with chlorine. With ozone the multiple antibiotics resistant strains were more resistant that reference strains. There were not statistical differences on ozone resistant inside of strains of same species, neither between Gram
