Oral lead bullet fragment exposure in northern bobwhite (Colinus virginianus).

Lead (Pb) is a worldwide environmental contaminant known to adversely affect multiple organ systems in both mammalian and avian species. In birds, a common route of exposure is via oral ingestion of lead particles. Data are currently lacking for the retention and clearance of Pb bullet fragments in gastrointestinal (GI) tract of birds while linking toxicity with blood Pb levels.

Lead pellet retention time and associated toxicity in northern bobwhite quail (Colinus virginianus).

Birds are exposed to Pb by oral ingestion of spent Pb shot as grit. A paucity of data exists for retention and clearance of these particles in the bird gastrointestinal tract. In the current study, northern bobwhite quail (Colinus virginianus) were orally gavaged with 1, 5, or 10 Pb shot pellets, of 2-mm diameter, and radiographically followed over time.

Evaluation of nonsurgical treatment of atlantoaxial subluxation in dogs: 19 cases (1992-2001).

Objective: To evaluate long-term neurologic outcome in dogs with atlantoaxial subluxation (AAS) that were treated nonsurgically with a cervical splint.

Design: Retrospective study.

Animals: 19 dogs with AAS and managed with a cervical splint.

Renal osteosarcoma in a dog.

A seven-and-a-half-year-old dog presented with anorexia, lethargy and haematurla. A 1.8 kg abdominal mass was excised and determined to be a primary renal osteosarcoma.
