Pro9-3 and its analogs have biofilm inhibition properties against CRAB. The antibiofilm activities of peptides (0–32 μM, 16 h) on (A) A. baumannii and (B) CRAB C0 strains were measured by crystal violet staining and the number of attached cells were read at 595 nm. Melittin, meropenem and imipenem were used as a control. Data are shown as the mean ± SEM (n = 3) and are statistically significant at * p < 0.05; *** p < 0.001; ns, not significant (two-way analysis of variance (ANOVA) with Dunnett’s comparison test).
