17) Additionally, blocking of the secondary bronchi and associated parabronchi through egg deposition in the lungs and edema formation predisposes affected birds to secondary pneumonia with Pseudomonas, Klebsiella, or Aspergillus species.
Some dark-brown rounded shapes were scattered throughout the atrial wall of parabronchi, being also contained in macrophages (Figure 3).
Heat loss occurs during anesthesia because of the constant need for air flow across the parabronchi.
Other microscopic lesions were found in the lungs, in which yeasts either were present in small numbers within parabronchi or in large collections effacing large portions of the pulmonary architecture, with marked expansion of air spaces progressing to rupture and formation of confluent spaces containing myriad yeasts (Fig 4C).
Finally, air flows from the parabronchi into the inner branch and out through the trachea.
2] in birds under anesthesia, although, as gas exchange in birds occurs in parabronchi via a cross-current mechanism of oxygen uptake and C[O.
The lung contained eosinophilic homogeneous material (edema) admixed with colonies of coccoid-shaped bacteria and plant material within parabronchi.
Abundant, 30-60-[micro]m-diameter, larvated, thick-walled ova were found in the bronchi and parabronchi, within the mesentery, and in the serosa of multiple coelomic organs.
Larger granulomas effaced the pulmonary parenchyma, whereas smaller granulomas were closely associated with parabronchi (Fig 6).
