FIG. 3.

Effects of csrA on 24-h biofilms grown in microtiter wells. (A) MG1655 (bars 1 to 3) or its csrA mutant (bars 4 to 6) containing plasmids pCSR10 (csrA) (bars 2 and 5) or pUC19 (bars 3 and 6). (B) Urinary tract pathogens E. coli P18 (bars 1 to 3) and C. freundii P5 (bars 4 to 6) containing plasmids pCSR10 (csrA) (bars 2 and 5) or pUC19 (bars 3 and 6). (C) Food-borne pathogens E. coli O157:H7 (bars 1 to 3) and S. enterica serovar Typhimurium ATCC 14028 (bars 4 to 6) containing plasmids pCSR10 (csrA) (bar 2), pSTCSR5 (S. enterica serovar Typhimurium csrA) (bar 5), or pUC19 (bars 3 and 6). Each bar shows the averages and standard errors of three separate experiments, and asterisks denote significant differences between strains (P < 0.0001).
