Abstract A 13-year-old female double yellow-headed Amazon parrot (Amazona ochrocephala oratrix) was examined for respiratory distress and partial anorexia. Radiographs, ultrasonography, and computed tomography revealed a soft-tissue opacity in the right cranial coelom with a necrotic or fluid-filled center.

An adult, male double yellow-headed Amazon parrot (Amazona ochrocephala oratrix) was diagnosed with chronic lymphocytic leukemia based on results of a complete blood cell count and cytologic examination of a bone marrow aspirate. Treatment with oral chlorambucil was attempted, but no response was evident after 40 days.

In this study, we describe 2 new species of Eimeria associated with the yellow-crowned Amazon Amazona ochrocephala. Eimeria amazonae n. sp. has bilayered, ellipsoidal, and smooth oocysts that measure 48.9 × 36.2 µm; the length/width ratio is 1.35. The micropyle and oocyst residuum are both absent, but the polar granule is present.

A 35-year-old yellow-naped Amazon parrot (Amazona ochrocephala auropalliata) was presented for gradually increasing inappetence, ataxia, weakness, and lethargy. Radiographic and ultrasonographic findings were strongly suggestive of atherosclerosis. Isoxsuprine, a peripheral vasodilator demonstrated to be of benefit in humans with intermittent limb pain,

Tracheal luminal stenosis can cause clinical respiratory distress in wild birds. We describe a case of tracheal stenosis due to diffuse ossification with osteopetrosis of tracheal rings in a yellow-crowned parrot (Amazona ochrocephala) with a history of chronic respiratory distress and death after development of marked dyspnoea.

Nachweis eines Herpesvirus bei Amazonen (Amazona aestiva und A. ochrocephala)
Zentralblatt für Veterinärmedizin Reihe B, 2010Zusammenfassung Aus Amazonen konnte ein Virus isoliert werden, das aufgrund seiner physikalisch-chemischen Eigenschaften sowie seiner Morphologie als aviares Herpesvirus angesprochen wurde. Im Kreuzneutralisationstest erwies sich das Virus als nicht verwandt mit dem Virus der Marekschen Krankheit sowie Puten-, Tauben-, Uhu-, Lake Victoria Cormorant-
