Protein HilD of Salmonella Typhimurium coordinates motility and host cell invasion by upregulating flagellar genes and a secretion system. Here, Cooper et al. show that HilD also modulates swimming behaviour by upregulating a subunit of the chemotactic receptor array, and this is important for invasion of epithelial cells.
