On the basis of electron microscopic images, we show that the flagellar filaments from Campylobacter jejuni have seven protofilaments rather than the 11 in S. typhimurium. The vertebrate Toll-like receptor 5 (TLR5) recognizes a region of bacterial flagellin that is involved in subunit-subunit assembly in Salmonella and many other pathogenic bacteria, and this short region has diverged in Campylobacter and related bacteria, such as Helicobacter pylori, which are not recognized by TLR5. The driving force in the change of quaternary structure between Salmonella and Campylobacter may have been the evasion of TLR5. | |||||||||
