| 英文描述 | Psittacine beak and feather disease syndrome caused by a CIRCOVIRUS develops in young psittacine birds of both sexes and might become apparent with the first generation of contour feathers. There is progressive and symmetrical loss of contour feathers and down. In some birds there are associated beak and claw lesions including: a change in color of the beak to a glossy black; progressive elongation of the upper and lower beaks; development of fault lines; fracture or breakage; and underrunning of the oral surface. There are no diagnostic laboratory findings other than feather shaft histology. A syndrome of liver necrosis in the absence of feather and beak abnormalities might occur in young African grey parrots. |
