Abstract
- Valvano, M.A., 1992. Diphenylamine increases cloacin DF13 sensitivity in avian septicemic strains of Escherichia coli. Vet. Microbiol., 32:149-161. Thirteen avian septicemic isolates of Escherichia coli were examined for the presence of the aerobactin iron transport system. All of the strains possessed a functional aerobactin system and hybridization experiments showed that the aerobactin genes were located on ColV-type plasmids in all cases. The expression of the aerobactin receptor IutA was also studied by determining the bacterial susceptibility to the bacteriocin cloacin DFI 3. Twelve of the 13 isolates were cloacin-resistant but became sensitive to this bacteriocin upon treatment with diphenylamine which caused a reduction in the amount of O-side chain lipopolysaccharide.
