Fig. 4.

Efficacity of phages vAbBal23 and vAbAbd25 to reduce preformed biofilms for strains (A) AB12, (B) AB13 and quantification of planktonic and biofilm (C) AB12, (D) AB13 after phage treatments. The biofilm biomass and bacterial cell viability were determined by the crystal violet assay and the colony counting method, respectively. The data are illustrated in a violin plot derived from a biological triplicate and technical triplicate experiments. The statistical significance is denoted as “*” for p-value < 0.05, “**” for p-value < 0.01, “***” for p-value < 0.001, and “****” for p-value < 0.0001
