Basal Cell Carcinoma in a Blue-Fronted Amazon Parrot (Amazona aestiva)
Avian Diseases, 1997Tumors of the integumentary system are relatively common in companion birds. Dermal tumors in pet birds can be epithelial, mesenchymal, or vascular in origin. Basal cell carcinomas appear to be extremely rare in birds. An adult female blue-fronted Amazon parrot was examined because it exhibited bilateral cervical masses that extended from the base of ...

Abstract In the face of increasing bacterial drug resistance because of β-lactamase production, many microbial infections can be treated effectively by combining clavulanic acid with amoxicillin. Judicious drug use that includes defining the optimum dosage is important to control development of resistance to this drug combination.

Intestinal acinar adenocarcinoma in a blue-fronted Amazon parrot (Amazona aestiva)
Journal of Comparative PathologyA 54-year-old captive male blue-fronted Amazon parrot (Amazona aestiva) was presented with progressive weight loss, diarrhoea and dyspnoea. Contrast radiographs suggested a neoplastic process by revealing an opaque soft tissue mass occupying most of the coelomic cavity. Post-mortem findings included approximately 80 ml of serous ascitic fluid.
