Immunopathogenesis of Salmonellosis
Salmonella is an intracellular pathogenic, gram-negative, facultative anaerobe and non-spore-forming and usually a motile bacillus that leads to salmonellosis in the host. It is a common food-borne disease that ranges from local gastrointestinal inflammation and diarrhoea to life-threatening typhoid fever and presents usually a serious threat to public health due to its socio-economic value. Inadequate sanitation and impure water help in the propagation of this disease. Despite advancement in the sanitation standards, Salmonella enters the food chain and affects communities globally. There is an immediate need to develop improved vaccines to minimise Salmonella-related illnesses. Some Salmonella serovars infect a wide range of hosts, while others are known to be host restricted. Many different factors determine the adaptability and host specificity of Salmonella. The host-pathogen interactions play a unique role in Salmonella invasion and progression which needs to be studied in detail. This chapter shall focus on our current understanding of Salmonella invasion, pathogenesis and interactions with the host, host specificity and adaptability.
