Ethanolamine Utilization Contributes to Proliferation of <i>Salmonella enterica</i> Serovar Typhimurium in Food and in Nematodes

Abstract excerpt

Only three pathogenic bacterial species, Salmonella enterica, Clostridium perfringens, and Listeria monocytogenes, are able to utilize both ethanolamine and 1,2-propanediol as a sole carbon source. Degradation of these substrates, abundant in food and the gut, depends on cobalamin, which is synthesized de novo only under anaerobic conditions.
