This study identifies that a minimal glycocalyx on host cell membranes optimally facilitates Salmonella Typhimurium targeting, with glycoproteins and cholesterol playing key roles.

The paper shows that the pcnB gene in Shigella flexneri promotes virulence by sustaining optimal levels of the virulence plasmid pINV, enhancing colonization and infection.

This study compares Salmonella and Shigella colonization strategies in human enteroids and colonoids, identifying distinct virulence factor modules that drive divergent infection kinetics and epithelial colonization patterns.
