Coprophagy in animals: a review.

Coprophagy is performed by rodents and lagomorphs and to a lesser degree by piglets, foals, dogs and nonhuman primates. Due to the construction of the digestive system of rodents and rabbits, coprophagy is necessary to supply many essential nutrients. Bacterial synthesis of nutrients occurs in the lower gastrointestinal tract in these animals where little absorption is realized.

Atypical mycobacteria as the probable cause of positive tuberculin reactions in squirrel monkeys (Saimiri sciureus).

Three of 275 squirrel monkeys (Saimiri sciureus) demonstrated a positive reaction to Koch's old tuberculin within 72 hours after the test. The animals were again positive when retested 1 week later. Two of the monkeys were killed and necropsied.
