FIG. 3.

Time-proliferation curves for MRSA EDCC 5248. The proliferation of MRSA EDCC 5248 on high-porosity silver-loaded bone cement samples was clearly dose dependent. The addition of 0.1% silver did not lead to a considerable delay in the onset of proliferation compared to the onset for plain bone cement samples in all six lanes. Loading the cement with 0.5% silver resulted in a prolonged lag phase, and the addition of 1% silver led to complete inhibition of bacterial proliferation in all six lanes. y axis, OD; x axis, 0 to 36 h.
