Biofilm formation acts as a major driver of antimicrobial resistance, allowing bacteria to withstand antibiotic concentrations 10 to 1,000 times higher than their planktonic counterparts. Biofilms represent one of the most adaptable microbial features that significantly contribute the virulence of pathogenic bacteria. The enhanced survival mechanism promotes the emergence of multi-drug resistance bacteria posing the greatest threat to human health worldwide. Therefore, the evaluation of multi-drug resistant biofilm-forming bacteria needs to be undertaken to improve treatment strategies and clinical outcomes. The present study focuses on the identification, and analysis of biofilm forming ability among clinical isolates collected form the hospitals in Namakkal district, Tamil Nadu, India. Out of all isolates tested, biofilm production varied among species, Higher biofilm formation was observed in Klebsiella spp., Pseudomonas spp., Staphylococcus spp., Enterococcus spp., Vibrio spp., and Shigella spp. Moderate biofilm formation was observed in Escherichia spp. and Proteus spp. In contrast no biofilm formation in Salmonella spp. Furthermore, the biofilm-producing bacterial isolates demonstrated higher multi-drug resistance compared to non-biofilm producers, indicating a strong association between biofilm formation and antimicrobial resistance.
KEYWORDS
In conclusion, this study demonstrates a strong positive correlation between biofilm production and multidrug resistance profiles among clinical bacterial isolates. The high prevalence of MDR strains among biofilm-forming Klebsiella spp., Pseudomonas spp., and Staphylococcus spp. underscores the clinical challenge these pathogens present. These findings highlight the need for systematic epidemiological surveillance of biofilm-producing phenotypes in clinical settings and the development of targeted anti-biofilm therapeutic strategies to disrupt the EPS matrix and restore antibiotic efficacy.
