Growth promotion of S. enterica serovar Typhimurium strain TA2700 and its derivatives was assessed on Vogel-Bonner medium supplemented with 200 μM 2,2′-bipyridyl. Growth promotion of S. enterica serovar Typhimurium strain ATCC 14028 and its derivatives and of S. enterica serovar Enteritidis strain SE147Nalr and its derivatives was assessed on egg white agar plates. The fepA, iroN, and cir genotypes of the strains are shown as follows: +, wild type; −, mutant. Symbols: +, a halo of growth around filter paper disks to which the compounds had been applied; −, no growth. All strains listed in a column had the same genotype and showed the same growth characteristics.
