Interpretive Summary: Salmonella are ubiquitous and have been recovered from insects and nearly all vertebrate species, especially humans, livestock and companion animals. Globally, salmonellosis has tremendous economic impact. Because of this impact we have written a state of the art synopsis of the characteristics of the disease it causes, as well as a review of control measures. This information is included in a book entitled Foodborne Diseases, 2nd Ed., which also includes information on other foodborne bacteria. This information is useful to other scientists, producers and commodity groups as well as public stakeholders, who need a complete summary of Salmonella as we know and understand the pathogen today. The utility of such an effort is that it summarizes years of research and provides a mean of developing new research directions.
Technical Abstract: Salmonella are ubiquitous and have been recovered from insects and nearly all vertebrate species, especially humans, livestock and companion animals. Globally, salmonellosis has tremendous economic impact. This chapter was written to summarize research on Salmonella. The chapter includes detailed descriptions of the characteristics of the organism, as well as the characteristics of the diseases it causes in mammalian hosts. New pathogenic mechanisms are described, including a detailed description of the virulence factors the organism uses to colonize hosts and cause disease. One important inclusion that is often omitted from other references is our description of the transmission of Salmonella between hosts. We also included discussions on isolation, identification, or surveillance systems that exist for Salmonella. Treatment options and prevention of salmonellosis in humans and production animals is also discussed.
