Comparison of Different Betadine and Saline Combinations on Microorganisms: An Original Research.

Abstract

Pathogenic bacteria in the oral cavity or a physiological microbiome imbalance can cause or maintain disease. Thus, this work examined a novel betadine-saline combination for antibacterial and antifungal activities. This study was in vitro. Betadine, saline, and their mixtures were tested for Bacillus subtilis, Staphylococcus aureus (gram-positive), Pseudomonas aeruginosa, Escherichia coli, and Aspergillus niger (gram-negative). Pour plate and disc diffusion methods were used to test CFUs, DZI, and RZI for various agent combinations. For Lactobacillus acidophilus, Betadine 90% + saline 10% had the greatest DZI and RZI at 24 and 12 mm, respectively. For E. coli, Betadine 50% + saline 50% had the highest at 16 and 8 mm. Betadine 60% + saline 40% had 14 mm RZI and the highest antifungal activity. The novel betadine-saline antibacterial and antifungal combination performed well. In vivo research should confirm the existing findings.
