Motility and plaque assays of flagellar mutants and their complementation strains. (A) One μl of an overnight culture was spotted in the middle of a swim plate and incubated at 37°C for 8 h. (B) Serially diluted phages were spotted onto plates of the wild type (SL1344), its isogenic flagellar mutants (ΔfliR [CH501] and ΔflgK [CH502]), and their complementation strains (ΔfliR/pACYC-fliR [CH511] and ΔflgK/pACYC-flgK [CH512]), respectively. The serially diluted phages from 102 to 109 PFU/ml were used as indicated inside the circle.
