Effect of heat-inactivated phage and divalent cations on biofilm formation on catheter surface. ♦, mean log CFU/cm2 of viable S. epidermidis 414 recovered from hydrogel-coated catheters; ▪, mean log CFU/cm2 of viable S. epidermidis 414 recovered from hydrogel-coated catheters (MHB supplemented with divalent cations); ○, mean log CFU/cm2 of viable S. epidermidis 414 recovered from hydrogel-coated catheters pretreated with heat-inactivated phage 456; □, mean log CFU/cm2 of viable S. epidermidis 414 recovered from hydrogel-coated catheters pretreated with heat-inactivated phage 456 (MHB supplemented with divalent cations). Error bars represent ±standard deviation (n = 3).
