ADENOMA OF THE GALLBLADDER IN A CHIMPANZEE (PAN TROGLODYTES)

Journal of Zoo and Wildlife Medicine, 2002
A 37-yr-old chimpanzee (Pan troglodytes) died due to bacterial meningoencephalomyelitis. At necropsy, a mass was observed in the fundus of the gallbladder. Histopathologic examination resulted in a diagnosis of adenoma, the first diagnosis of a primary spontaneous neoplasm in the gallbladder of a non-human primate.

Delay of gratification in chimpanzees(Pan troglodytes)

Developmental Psychobiology, 1999
Delay of gratification in 3 chimpanzees (Pan troglodytes) was examined by using a paradigm based on research with children. The chimpanzees either pressed a door-bell button during a trial and received one reward (the immediate reward) or did not press the doorbell and received another reward (the delayed reward). Two chimpanzees were language-trained,

Dentoalveolar abscess variation among three groups of chimpanzees (Pan troglodytes schweinfurthii, Pan troglodytes troglodytes, and Pan paniscus)

International Journal of Paleopathology, 2012
The prevalence and pattern of periodontal and periapical dental abscess lesions are examined in 399 wild caught chimpanzee mandibles and maxillae from museum contexts (138 Pan troglodytes troglodytes, 152 Pan troglodytes schweinfurthii and 109 Pan paniscus). This study tests two predictions.
