Some types of Salmonella cause disease in food animals, like pigs. Others cause foodborne illness in humans. A new vaccine developed by Agricultural Research Service (ARS) scientists in Ames, Iowa, protects against these types of Salmonella in food animals.
Most Salmonella vaccines only protect against one type of the pathogen. This leaves pigs susceptible to disease from other Salmonella pathogens. While some Salmonella vaccines reduce disease in pigs, they may not protect against Salmonella that causes foodborne illness in humans.
Microbiologists Shawn Bearson and Brad Bearson, at ARS's Food Safety and Enteric Pathogens Research Unit and ARS's Agroecosystems Management Research Unit, respectively, developed a new vaccine that protects food animals against both human and animal disease-causing Salmonella.
