title: Incompatibility of citrate utilization plasmids isolated from Escherichia coli.
abstract: The 57 conjugative Cit plasmids isolated from 72 citrate-utilizing (Cit+) Escherichia coli strains from various sources were classified into four groups on the basis of their genetic properties. Escherichia coli K13 strains carrying these Cit plasmids could utilize cis-aconitate or tricarballylate, in addition to citrate.
