N‐acetyllactosamine‐induced retraction of bundle‐forming pili regulates virulence‐associated gene expression in enteropathogenic Escherichia coli

Enteropathogenic Escherichia coli (EPEC) are a major cause of infant morbidity and mortality due to diarrhoea in developing countries. The pathogenesis of EPEC is dependent on a coordinated multi-step process culminating in the intimate adherence of the organisms to the host's intestinal mucosa. During the initial stages of the EPEC colonization process, the fimbrial adhesin, bundle-forming pili (BFP), plays an integral role. We previously …
