Abstract/OtherAbstract:
Salmonella enterica serovar Typhimurium produces two types of filamentous appendages on its surface. Fimbriae mediate adherence to tissues and cells via receptor-specific interactions, and flagella are the organelles of motility. These appendages play a role in colonization and dissemination, respectively, from infected surfaces and may be important components of bacterial survival. Increased expression of FimZ in serovar Typhimurium resulted in bacteria which were hyperfimbriated but were nonmotile in soft agar. This lack of motility was associated with down regulation of the flhDC master flagellar operon. Therefore, FimZ represents a molecular connection between flagella and fimbrial formation in serovar Typhimurium, indicating that the synthesis of flagella and fimbriae are oppositely controlled.
