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.
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.
People can also get sick if a bird bites them or through beak-to-mouth contact. The disease is not spread through eating infected animals. Human-to-human transmission is possible but rare, studies ...
[5] [6] [7] Human infection with animal influenza viruses is rare, as they do not transmit easily to or among humans. [8] However, avian and swine influenza viruses in particular possess high zoonotic potential, [9] and these occasionally recombine with human strains of the flu and can cause pandemics such as the 2009 swine flu. [10]
Less common is infection from bites and beak-to-mouth contact. The health district recommends no contact between birds and children younger than 5, adults older than 65 and people who are ...
The 1929–1930 psittacosis pandemic, also known as the psittacosis outbreak of 1929–1930 and the great parrot fever pandemic, [2] was a series of simultaneous outbreaks of psittacosis (parrot fever) which, accelerated by the breeding and transportation of birds in crowded containers for the purpose of trade, was initially seen to have its origin in parrots from South America.
Humans have become infected while visiting forested areas and are believed to be responsible for helping the virus make its way to towns and cities, but person-to-person transmission hasn't been ...
P. multocida causes atrophic rhinitis in pigs; [4] it also can cause pneumonia or bovine respiratory disease in cattle. [5] [6] It may be responsible for mass mortality in saiga antelopes. [7] In humans, P. multocida is the most common cause of wound infections after dog or cat bites. The infection usually shows as soft tissue inflammation ...
