2. (D) Infection by one of several Salmonella species
(not typhi) leads to a self-limited diarrhea. This is a form
of food poisoning, typically from contaminated poultry
products. E enterocolitica is most often found in contami-
nated milk or pork products and may disseminate to pro-
duce lymphadenitis and further extraintestinal infection. A
variety of diseases result from contamination with various
strains of E. coli, based on the characteristics of the orga-
nisms and whether they invade or produce an enterotoxin.
Poultry products are usually not contaminated with E. coli.
Amebiasis from E. histolytica can be an invasive, exuda-
tive infection. The stools contain blood and mucus. Rotavi-
rus is most often seen in children; in adults, a self-limited
watery diarrhea is the rule; there is no particular associa-
tion of this infection with a specific food product.
