Fig 6. Oxidative stress and bioflim formating assay in K. pneumoniae strains.

(A) Diagram showing the zone of inhibition in different strains due to the different concentration of H₂O_2. In this study 0%, 0.1%, 1%, 3%, and 10% of H₂O₂ were used as oxidative stress inducing agent. The diagram represents the mean of three independent experiments. (B) Biofilm formation by the K. pneumoniae isolates are shown here: i) tubes showing stained biofilm rings in few representative isolates ii) graphical presentation of biofilm formation among the isolates is shown as the ratio of OD_570nm and OD_600nm. The bar graph represents the mean of three independent experiments.
