Recombination of Salmonella phase 1 flagellin genes generates new serovars.

Abstract excerpt

To determine the evolutionary mechanisms generating serotypic diversity in Salmonella strains, we sequenced the central, antigen-determining part of the phase 1 flagellin gene (fliC) in strains of several serovars for which estimates of chromosomal genomic relatedness had been obtained by multilocus enzyme electrophoresis. The nucleotide sequence of this region was identical in several chromosomally divergent...
