Acute infection of the stomach may produce diffuse phlegmonous or suppurative gastritis. This rare condition probably arises from preexisting disease of the stomach, such as damage by ethanol or noxious agents, chronic gastritis, trauma, or upper gastrointestinal surgery. Alpha-hemolytic streptococci are the most common organisms involved, although P vulgaris and other bacteria (eg, E coli, Clostridium perfringens, Bacillus subtilis, staphylococci, pneumococci) have been implicated. Suppurative gastritis is a medical emergency with a high mortality rate and may necessitate surgical resection after appropriate treatment with fluids, electrolytes, and antibiotics.
