Summary An Escherichia coli K12 flagellin gene, hag48, was found to be expressed in the presence of the Salmonella rh1 gene product. The strains which had hag48 on a chromosome or on an F′ factor were constructed from strains H2-e,n,x on-off rh1 + and fixed H2-e,n,x on rh1 + in which rh1 + is contranscribed with H2 in its “on” state. Motility of these strains in semisolid medium was inhibited by anti-H48 serum and motile clones (swarms) that escaped from it were hag mutants in case of the hag48 e,n,x on-off strain tested. H48 flagellin was detected by electrophoresis, though its amount was less than e,n,x flagellin, from all the strains that were nonmotile in the presence of anti-H48 serum.
