| Popis: | Background: Pseudomonas aeruginosa biofilm is an essential component of virulence that plays a significant role in antimicrobial resistance and chronic burn wound infections. Objective: This study aimed to investigate the biofilm formation capacity of P. aeruginosa isolated from chronic burn wound from January to May 2022 by biochemical and molecular techniques. Materials and Methods: Quantification of biofilm was performed based on tube method for local isolates of P. aeruginosa after growing on brain heart Broth. The genes encoding exopolysaccharides (algD, pelF, and pslD) were targeted by using conventional polymerase chain reaction (PCR). Results: The results showed that 92.6% of isolates were biofilm former, interestingly 68% of isolates were considered as strong former comparing with other biofilm categories. Gel electrophoresis result of PCR products presented clear bands for algD and psID genes with percentages (96%) and (3.7%) respectively. However, there was no PCR product for pelf gene among all isolates. Conclusion: The prevalence of algD, the large operon necessary for alginate production, was high among P. aeruginosa biofilm producer in this study and it can be an essential agent in the pathogenicity of P. aeruginosa burn wound infections comparing with other biofilm genes (pelF and pslD) of exopolysaccharide structure. |
