A study of conjugation between typed strains ofEscherichiacoli belonging to different O serogroups and of conjugation between typed and untyped strains showed that the genetic determinant controlling synthesis of the O100 antigen is closely linked with the histidine locus. Among recombinants isolated from crosses between typedE.coli cells some were found to have a different serotype from that of the donor and recipient cells.Department of Biology and General Genetics, Patrice Lumumba Peoples' Friendship University.
