[Evaluation of antimicrobial activity antiseptics and disinfectants used in a public health service].

The study aimed to determine the in vitro antimicrobial activity of antiseptics and disinfectant used in the care service primary health of a city in northern Paraná, using microorganisms standardized by the National Institute of Quality Control in Health, Oswaldo Cruz Foundation. For this purpose, we performed tests of antimicrobial activity and chemical stability of three samples of antiseptic and one disinfectant used in the service. From the analysis performed the first, seventh, fourteenth and twenty-first day after the opening of the bottles, it was found that the samples retained their activity in vitro antimicrobial regarding standardized strains, as evidenced by the absence of growth of colony-forming units and maintaining the chemical stability. The study demonstrated the efficacy of the samples against analysis microbiological in vitro using standardized microorganisms.
