Salmonella Dublin is a type of bacteria that primarily infects cattle, but some strains also can adapt to infect humans. It is increasingly becoming resistant to antibiotics, making it a growing public health threat, according to the U.S. Centers for Disease Control and Prevention. Researchers at Penn State have investigated how strains of the pathogen—which can cause severe illness and death in cattle and blood infections and hospitalization in humans are evolving and spreading across humans, cattle and the environment in the United States.
