Public Health Relevance: Salmonella infection is a major public health problem with Salmonella spp. causing more than one billion new human infections each year that lead to more than three million deaths1. The problem is greatly exacerbated by the emergence of multi-drug resistant strains2. It is the goal of this work to understand how, when, where and why pathogens move within their hosts. The answers to these questions may directly affect human health.
