Resistencia de klebsiella pneumoniae frente a desinfectantes de uso hospitalario

Abstract

Introduction: Klebsiella pneumoniae is considered a gram-negative bacillus pathogen responsible for intrahospital infections affecting health and having a high morbidity and mortality rate. On the other hand, resistance to antibiotics, disinfectants, and biocides is one of the main and important threats to humanity worldwide; for this reason, they apply techniques to prevent these bacteria, disinfectants, and their use as the first option to prevent these types of infections. Objective: This research aims to evaluate the inhibition of Klebsiella pneumoniae against hospital disinfectants: sodium hypochlorite, glutaraldehyde, chlorhexidine, quaternary ammonium potassium monopersulfate, and iodopovidone. Materials and methods: The methodology was descriptive, empirical, and cross-sectional and involved the evaluation of the minimum inhibitory concentration of hospital disinfectants against Klebsiella pneumoniae ATCC 700603. Results: The results determined that Klebsiella pneumoniae ATCC 700603 showed resistance to glutaraldehyde at 0.25% and 0.5%, potassium monopersulfate from 0.1% to 1%, and iodopovidone at 2%. Conclusion: Sodium hypochlorite 0.5% to 5%, quaternary ammonium 2% to 10%, chlorhexidine 0.5% to 4% showed disinfecting effects on Klebsiella pneumoniae ATCC 700603, while glutaraldehyde 0.25% and 0.5%, potassium monopersulfate 0.1% to 1% and iodopovidone 2% showed an inhibitory effect as there was no growth in the tubes.
