Unusual pox lesions found in Chinese jungle mynahs (Acridotheres cristatellus)

Figures & data

Figure 1.  Several rounded pox lesions with or without ulceration (arrows) are found on the oral mucosa.

Figure 2.  A large greyish-white nodule is protruding from the rump.

Figure 3.  (a) The normal acinar cells of the uropygial gland are replaced by adenomatoid proliferation cells (haematoxylin and eosin, bar = 100 µm), (3b) The proliferating cells show vacuolar degeneration and contain irregular cytoplasmic inclusions) (haematoxylin and eosin, bar = 20 µm), (3c) Electron micrograph of a cytoplasmic inclusion from an affected uropygial gland containing many poxvirus particles (bar = 1 µm).
