Figure 1. Differential expression of virulence factors, quorum sensing molecules and biofilm formation genes in five P. aeruginosa (PA) wound isolates.
A. RT-PCR results showing expression of ToxA, RhlI, ExoS, AlgD and LasI; RpoD was used as a housekeeping gene. P. aeruginosa 09-010 isolate expressed all genes tested. B. In vitro biofilm assay by P. aeruginosa wound isolates. P. aeruginosa 09-010 has shown the most excessive biofilm production. The result is a summary of three independent experiments each repeated in triplicates.
