Combined infection by avian poxvirus and Collyriclum faba in an American crow (Corvus brachyrhynchos).
An adult American crow (Corvus brachyrhynchos) from Virginia, USA, was diagnosed with combined infection of avian poxvirus and the skin fluke Collyriclum faba. The flukes and viral inclusions were combined in a large (4 x 4 cm) multilobulated proliferative mass on the ventrum just cranial to the cloaca. The flukes were identified using light microscopy of organisms obtained by antemortem wedge biopsy. Intraepithelial cytoplasmic inclusions consistent with poxvirus infection were seen on histopathologic examination of the mass.
