Surface sensing and metabolic signals drive feedback regulation of long polar fimbriae in enterohemorrhagic Escherichia coli O157

Soumita Dutta, Walter J. Galdamez, Manuel Antonio Ramirez, Anne Marie Krachler

This study shows that long polar fimbriae in E. coli O157 integrate metabolic and surface signals through regulatory feedback, with fimbrial structures promoting colonization without requiring tip adhesins.
