A Virus Disease of Parrots and Parrakeets Differing from Psittacosis
نویسندگان
چکیده
The virus of parrots and parrakeets discovered by Pacheco, Bier, and Meyer is unrelated to the agent causing psittacosis either in birds or in man. The virus is fairly species-specific and manifests itself chiefly by the production of areas of focal necrosis in the liver and acidophilic intranuclear inclusions in affected cells.

BACKGROUND Psittacosis, an avian disease caused by Chlamydophila psittaci, can manifest as an acute, protracted, or chronic illness, but can also be asymptomatic. C. psittaci can persist in the host for months to years, often without causing obvious illness, and therefore poses a threat for zoonotic outbreak. We investigated the prevalence of C. psittaci from 156 tracheal swab samples from 34 d...
