Bacteria have several resistance mechanisms, one of which is biofilm production. The purpose of this study was to analyze the biofilm production of Klebsiella pneumoniae strains that are resistant to the antibiotic ciprofloxacin, as a form of defense mechanism. The in vitro research method was used to achieve the goal, carried out by testing clinical specimens of blood, sputum, pus, urine, feces, pleural fluid, with the process of isolation and identification, resistance testing and measuring biofilm production. The tested resistant K. pneumoniae isolates have a resistance mechanism by producing strong, medium and weak qualification biofilms, as well as low porin cell permeability. A strong significant correlation was formed in biofilm production with the amount of bacterial cell growth at the MIC value, which can increase cases of resistance prevalence.</em></p> <p>&nbsp;</p> Indah Sulistiyawati Daniel Joko Wahyono Wahyu Siswandari Copyright (c) 2024 BioWallacea: Jurnal Penelitian Biologi (Journal of Biological Research) 2024-11-18 2024-11-18 11 2 154 166
