Sensitization of MRSA and MRSP to oxacillin by anti-ftsZ PNA. a CFU of NCTC 13142 was reduced by 87 % at 7.5 μM of anti-ftsZ PNA, Z46 compared to a reduction of 44 % by the scrambled PNA, scrZ. b CFU of HH-1 reduced significantly at all concentrations of Z46 compared to scrZ, except at 5 μM where Z46 and scrZ had similar effects. Relative CFU reduction was calculated as a ratio to an untreated control in each experiment. Values shown are mean ± SD, n = 3. *p < 0.05, **p < 0.01
