title: Molecular cloning and expression in Escherichia coli K-12 of chromosomal genes determining the O antigen of an E. coli O2: K1 strain.
abstract: The rfb gene cluster which determines the biosynthesis of the O2 O antigen has been cloned from an Escherichia coli O2: K1 strain isolated from a case of septicaemia in chickens. The region required for expression of the O antigen in E. coli K-12 was localised to a 10.7 to 14.15-kb segment which was shown to be chromosomal in origin with a close linkage to the gnd and his genetic loci.
