Established MRSE 35984 biofilms stained with crystal violet were treated with 600-Da BPEI for 20 h, as well as the negative and positive controls. The dissolved biofilm solutions were transferred to a new plate, and the biofilm remainders are shown as top-down view (A). The mean OD550 of the dissolved biofilms was measured (B). Error bars denote standard deviation (n = 10). The MRSE biofilms were significantly dissolved by 600 Da BPEI (t test, p-value < 0.01, significant difference between the negative control and each treatment is indicated with an asterisk).
