Aim: Escherichia coli, a bacterium that forms a biofilm, is mainly responsible for intestinal and extraintestinal infections, such as urinary tract infections, peritonitis, meningitis, and septicemia. Different antibiotics (Aminoglycoside, Fluoroquinolones, etc.) treatments are routinely used to overcome E.coli infections. The presence of biofilm increases E.coli resistance against antibiotics. The study aims to evaluate the boron component’s effect on the biofilm formation of E.coli in vitro via a liver (HepG-2) infection model.
Material and Method: The antibacterial activity of boron compounds on Escherichia coli was evaluated with Minimum inhibitory concentration. Antibacterial activity with the combination of boron compounds was assessed by fractional inhibitor concentration. The non-cytotoxic dose of boron compounds was determined in the infection model created with Escherichia coli in the cell line. Then, the effect on cell viability and pathological examinations were examined histopathologically.
Results: Synergistic effects (≤0.5) were watched at 32 μg/mL Etidote + 32 μg/mL Sodium perborate metahydrate, at Etidote 32 μg/mL + 32 μg/mL Zinc borate, and at Zinc borate 32 μg/mL + 32 μg/mL Sodium perborate metahydrate. It was determined that 128 μg/ml Etidote + 512 μg/ml Sodium perborate metahydrate, Etidote 512 μg/mL + Zinc borate 1024 μg/mL, and Zinc borate 512 μg/mL + Sodium perborate metahydrate 128 μg/mL had antibiofilm activity. In the cell line, it was determined that although Zinc borate + Etidote reduced the infection, it did not completely reduce it in its combination. Histopathological analyses also paralleled these results.
Conclusion: Boron components can be used against biofilmformed E.coli.
