Alteration of the activities of CAT, POD, and SOD in AgNP-treated multidrug-resistant Pseudomonas aeruginosa.

Notes: (A–C) The activity–time curves of CAT, POD, and SOD, respectively, when P. aeruginosa was exposed to AgNP treatment at different time points of 0, 0.5, 1, 1.5, 2, 3, and 4 hours, respectively. (D–F) The activity–concentration curves of CAT, POD, and SOD, respectively, when the bacteria were addressed by a series of AgNP concentrations of 0, 5.625, 11.25, 22.5, and 45 µg/mL, respectively.

Abbreviations: AgNP, silver nanoparticle; CAT, catalase; POD, peroxidase; SOD, superoxide dismutase.
