Hydrogen sulfide production distinguishes Salmonella from close relatives, but its biological significance remains obscure. This study uncovers the secret: Salmonella uses hydrogen sulfide production as a weapon to outcompete E. coli and gain a foothold in the gut. www.pnas.org/doi/10.1073/...

Salmonella invades the ileal mucosa to trigger lysine malbsorption, creating a a wave of lysine entering the cecum. Decarboxylation of lysine buffers the cytosol to protect against short-chain fatty acids, enabling the pathogen to invade the cecal ecosystem. www.pnas.org/doi/10.1073/...
