Its local lesions are a scanty eruption of spots, resembling flea bites, on the belly, enlargement of the spleen, and ulceration of the intestines over the areas occupied by Peyer's glands. The virus, or contagion, of this fever is supposed to be a microscopic vegetable organism, or bacterium. Called also enteric fever. See Peyer's glands.<-- caused by the gram-negative bacillus, Salmonella typhosa (syn. Salmonella typhi), also called typhoid bacillus. The organism is often ingested by drinking contaminated water. --> -- Typhoid state, a condition common to many diseases, characterized by profound prostration and other symptoms resembling those of typhus.
