The genes determining flagellar antigen specificities H36, H47 and H53 in the respective E. coli standard H test strains were found to be alleles of the flagellin gene hagB . Until now, only the allele encoding the flagellar antigen H3 has been identified. The chromosomal regions of flagellin genes hagB in E. coli and H2 in Salmonella were non‐homologous as these genes integrated at different sites in the E. coli K‐12 chromosome and were unable to replace each other. The hagA allele encoding E. coli flagellar antigen H48 was insensitive to the repressor produced by Salmonella gene rhl or by its putative analog in E. coli .
