Why We Study Salmonella and Francisella...


Each year, Salmonella enterica Serovar Typhi causes approximately 16 million new cases of typhoid fever and 600,000 typhoid-related deaths worldwide. Salmonella Typhimurium is a major contributor to gastroenteritis around the world.

In an age threatened by bioterrorism, Francisella Tularensis is among the most dangerous microorganisms known, categorized as a Category A Biodefense Agent by the Centers for Disease Control and Prevention.
