On Jan. 13, 2021, National Institutes of Health scientists and their colleagues announced they had identified a S. Typhimurium protein, McpC (Methyl-accepting chemotaxis protein C), that allowed the bacteria to swim straight when they are ready to infect cells.

This study, published in Nature Communications, describes S. Typhimurium movement and shows that McpC is required for the bacteria to invade surface epithelial cells in the gut.
