An In Vitro Comparison of PMMA and Calcium Sulfate as Carriers for the Local Delivery of Gallium(III) Nitrate to Staphylococcal Infected Surgical Sites

Figure 4

Effect of Ga(NO₃)₃ incorporation on bacterial colonization of PMMA and CaSO₄. Colonization of Ga(NO₃)₃ loaded PMMA (a-b) or CaSO₄ (c-d), 2.4%, 4.7%, 9.09%, and 13.0% (w/w), by S. aureus ATCC 12913 and S. epidermidis ATCC 12228 over time, as determined by CFU counts (log₁₀ CFU/mL per bead). Data is representative of mean ± SD. Statistical analysis was performed using an analysis of variance (ANOVA) with Dunnett’s post hoc test; indicates relative to control.
