[1] [3] Allergens may also come from other birds, including parakeets, cockatiels, budgerigars, parrots, turtle doves, turkeys, chickens, and other birds. [3] Antigens can also be from feathers in bedding. [2] [6] People who work with birds or own many birds are at risk. [3] Bird hobbyists and pet store workers may also be at risk.
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.
Psittacosis in birds and in humans often starts with flu-like symptoms and becomes a life-threatening pneumonia. Many strains remain quiescent in birds until activated by stress. Birds are excellent, highly mobile vectors for the distribution of chlamydia infection, because they feed on, and have access to, the detritus of infected animals of ...
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]
Most human cases of bird flu in North America have been mild, a fact that’s underscored by a new study of the first 46 confirmed human H5N1 infections in the United States this year.
Implicated birds included green Amazon parrots, canaries, lovebirds and shell parakeets. [9] [10] By early 1930, the disease was reported in humans in several countries around the world, accelerated by the popular hobby of domestic bird-keeping at the time. Many cases and clusters had links with sick parrots. Around 750 to 800 people were affected.
Cats can not only catch bird flu, they can also catch human flu viruses. That means cats can serve as a "mixing vessel" for the two types of flu, allowing them to combine and create a version of ...
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.
