Gastrointestinal (GI) infections are bacterial, parasitic, or viral infections
that cause gastroenteritis, an inflammation of the GI tract. A wide range of GI diseases are caused by bacteria, when bacteria or its associated toxins are ingested through contaminated food or water. Though most
bacterial GI illness is short lived and self-limiting, it can be fatal, if not treated properly.
This remains a common problem in both primary care and emergency centers in the developing world. Some of the major bacteria that causes GI illness include Escherichia coli, Salmonella spp., Shigella, Campylobacter spp., Clostridium spp., Yersinia, and Bacillus cereus. This chapter discusses different types of causative bacteria, mode of infection, and mech anism that contributes to patho physiology of the disease. This review also adds a note on various methods and challenges in diagnosis and treatment of bacteria causing GI infections.
