Chlamydia psittaci is a lethal intracellular bacterial species that may cause endemic avian chlamydiosis, epizootic outbreaks in other mammals, and respiratory psittacosis in humans. Potential hosts include feral birds and domesticated poultry, as well as cattle, pigs, sheep, and horses.
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.
In addition, a cockatiel purchased at the flea market tested positive for avian chlamydiosis, sometimes called “parrot fever.” It is a bacterial infection that can cause the illness ...
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.
Upon re-exposure to avian proteins, sensitized individuals typically experience symptoms within 4–8 hours. [3] In chronic BFL, symptoms may include anorexia, [3] weight loss, [3] extreme fatigue, and progressive pulmonary fibrosis. Pulmonary fibrosis is generally the most serious consequence of the disease, as it progressively and ...
