Flagellin and fimbrial protein production of CFT073 MMR mutants in wild-type and fim L-ON backgrounds. Western blot analysis of flagellin production, FliC (60 kDa), and fimbrial production, FimA (15 kDa). The “+” and “−” signs indicate the fim L-ON status of the CFT073 background; “+” represents CFT073 fim L-ON, and “−” represents CFT073 wild type.
