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,

Addendum to "Summation in the chimpanzee (Pan troglodytes)."

Journal of Experimental Psychology: Animal Behavior Processes, 1988
Rumbaugh, Savage-Rumbaugh, and Hegel (1987) reported that two chimpanzees (Pan troglodytes) could select, with better than 90% accuracy, the greater of two paired quantities of chocolate chips. In that study, no one quantity of chocolates (from 0 through 5) was used in both pairs on a given trial.

Diabetes mellitus in the Chimpanzee (Pan troglodytes)

Journal of Medical Primatology, 1981
Glucose intolerance was found in four adult chimpanzees. The response of glucose, insulin, C-peptide, and glucagon to intravenous glucose and tolbutamide stimulations revealed impaired glucose clearance, deficient pancreatic secretion of insulin and C-peptide, and elevated glucagon levels.

Pan troglodytes (Chimpanzee)

1967
At least 25 animals have now been studied with similar findings, Chiarelli, and Hamerton et al. report minor structural differences for the subspecies P. t. paniscus (pygmy chimpanzee). Satellites occur on the short arms of the acrocentrics. The Y may occasionally be metacentric (Chu and Bender).

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.

Satellite sequences in chimpanzee (Pan troglodytes)

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1973
Abstract Chimpanzee DNA was found to contain two satellite fractions when centrifuged in Ag+-Cs2SO4 density gradients: satellite A with a buoyant density of 1.696 gm/cm3 and satellite B with a buoyant density of 1.683 gm/cm3. It was shown that satellite A shares many of the physical properties of human satellite III, and cross hybridisation results ...

Detection and molecular characterization of foamy viruses in Central African chimpanzees of the Pan troglodytes troglodytes and Pan troglodytes vellerosus subspecies

Journal of Medical Primatology, 2006
AbstractBackground  Foamy viruses are exogenous retroviruses that are highly endemic in non‐human primates (NHPs). Recent studies, mainly performed in North America, indicated frequent simian foamy virus (SFV) infection in persons occupationally exposed to NHPs. This zoonotic infection was demonstrated mainly after bites by chimpanzees [Pan troglodytes

Imitation recognition in a captive chimpanzee (Pan troglodytes)

Animal Cognition, 2004
This study investigated the ability of a captive chimpanzee (Pan troglodytes) to recognise when he is being imitated. In the experimental condition of test 1a, an experimenter imitated the postures and behaviours of the chimpanzee as they were being displayed.

Successful reproduction in wild-released orphan chimpanzees (Pan troglodytes troglodytes)

Primates, 2003
We report a case of successful reproduction in wild-released orphan chimpanzees. Using non-invasive genetic analysis, we determined the paternity of an infant born to a female chimpanzee released by HELP (Habitat Ecologique et Liberté des Primates) Congo into the Conkouati-Douli National Park, Republic of Congo.
