The virus Psittacid alphaherpesvirus 1 is the etiologic agent that causes Pacheco's disease. This virus species is closely related to Gallid alphaherpesvirus 1. [2] It was initially identified as a herpesvirus by examining its virion size, sensitivity to ether, the formation of intranuclear inclusions, its ability to thicken the nuclear membranes of the host cells.
Psittacosis—also known as parrot fever, and ornithosis—is a zoonotic infectious disease in humans caused by a bacterium called Chlamydia psittaci and contracted from infected parrots, such as macaws, cockatiels, and budgerigars, and from pigeons, sparrows, ducks, hens, gulls and many other species of birds.
Psittacine beak and feather disease was first described in the early 1980s and has become recognised as the dominant viral pathogen of psittacine birds worldwide. In wild red-rumped grass parakeets (Psephotus haematonotus), a case of feather loss syndrome that was highly suggestive of PBFD was first recorded in South Australia in 1907. [2]
The orange-fronted parakeet is 23 to 25 cm (9.1 to 9.8 in) long and weighs 68 to 80 g (2.4 to 2.8 oz). The sexes are alike. Adults of the nominate subspecies E. c. canicularis have an orange-peach forehead (the "front") and lores, a dull blue mid-crown, and a dull green hindcrown, nape, and back.
