Study discovers an electric current in the gut that attracts pathogens like Salmonella

How do bad bacteria find entry points in the body to cause infection? This question is fundamental for infectious disease experts and people who study bacteria. Harmful pathogens, like Salmonella, find their way through a complex gut system where they are vastly outnumbered by good microbes and immune cells. Still, the pathogens navigate to find vulnerable entry points in the gut that would allow them to invade and infect the body.
