ZnPor concentration-dependent killing of PsA PAO1 cells and independent effects of ZnPor and PEV2 phage on the viability of H441 human lung cells. (A) Without photoactivation, 65 µg/mL ZnPor killed PsA cells with greater than a 3-log reduction. At the MIC (4 µg/mL), no change to PAO1 levels were identified (B) H441 cell viability was not significantly reduced by ZnPor at either 4 or 65 µg/mL following a 24 h exposure. (C) H441 cell viability was unaffected by the addition of a PEV2 phage at an MOI of 1:1 following 24 h exposure. Neither ZnPor nor PEV2 displays any statistically significant toxicity against H441 lung cells. * indicates statistical significance from untreated control (p < 0.05, n = 3).
