FIGURE 3.
Antibacterial activity of carbomer-based hydrogels on growth of planktonic cells of Streptococcus agalactiae. (A) Time-kill curve of S. agalactiae ATCC 13813; erythromycin and clindamycin-resistant GBS 66 strain; and erythromycin-resistant GBS 121 strain in presence of hydrogels. Bacteria were incubated with CARB-BF and CARB-CO 1.0 for 24 h at 37°C and the CFU counts per 10 μL were determined at specified time points. GBSs without treatment were used as growth control. (B) TSA plate assay. Values are mean ± standard deviation of two experiments.
