Streptococcus troglodytidis sp. nov., isolated from a foot abscess of a chimpanzee (Pan troglodytes).

A facultative anaerobic, non-motile, non-spore-forming, Gram-positive-staining, coccus-shaped bacterium was isolated from an abscess on the right foot of a chimpanzee (Pan troglodytes). The colonies were β-haemolytic. Catalase and oxidase activities were negative.

Occurrence of hepatocellular carcinoma in an adult male Nile lechwe (Kobus megaceros).

A 14-yr-old male Nile lechwe (Kobus megaceros) from the Jackson Zoo (Mississippi, USA) had chronic weight loss that was associated with elevated serum alkaline phosphatase levels. Approximately 4 yr after the first clinical signs of weight loss, the animal fractured its left rear femur and was subsequently euthanized; on the same day necropsy was performed. The liver was grossly enlarged and contained a smooth-surfaced nodular mass that occupied the majority of the right lobe of the liver.

Mortality associated with melarsomine dihydrochloride administration in two North American river otters (Lontra canadensis) and a red panda (Ailurus fulgens fulgens).

Two adult North American river otters (Lontra canadensis) and an adult red panda (Ailurus fulgens fulgens) at three separate institutions died within 22 hr after receiving single 2.5- to 2.7-mg/kg doses of melarsomine dihydrochloride administered in the epaxial musculature as a treatment for filarid nematodes.
