Two diphasic Escherichia coli strains, Bi7327‐41 and P12b, which spontaneously change their flagellar antigenic characters from H3 to H16, and from H17 to H4, respectively, were investigated. New features of the genetic control of flagellar phase variation in Bi7327‐41 and Salmonella were found. Two genes responsible for the alternative flagellar phases H17 and H4 were demonstrated in P12b. They differed from hagA (H16) and hagB (H3), the two flagellin genes of Bi7327‐41, in not being alleles of hagB (H3) or sensitive to the hagA (H16)‐specific repressor.
