The production of aerobactin has been suggested to be a virulence factor in Escherichia coli . We have studied the production of aerobactin in 155 E. coli strains, isolated from sewage, which carry conjugative antibiotic resistance plasmids, and 88 (57%) of these strains produced aerobactin, and 59 (38%) co‐transferred production of the siderophore and antibiotic resistance. In 35 (22%) of the transconjugants, both characters seemed to be encoded into the same plasmid. Those aerobactin‐producing‐antibiotic resistance plasmids had different sizes and antibiotic resistance patterns. The ecological implications of these results are discussed.
