The lungs become inflamed with granuloma formation. Bird fancier's lung (BFL), also called ''bird-breeder's lung'' and ''pigeon-breeder's lung'', is a subset of hypersensitivity pneumonitis (HP). This disease is caused by the exposure to avian proteins present in the dry dust of the droppings and sometimes in the feathers of a variety of birds. Birds such as pigeons, parakeets, cockatiels, shell parakeets (budgerigars), parrots, turtle doves, turkeys and chickens have been implicated. People who work with birds or own many birds are at risk. Bird hobbyists and pet store workers may also be at risk. ==Symptoms== This disease is an inflammation of the alveoli in the lungs. Initial symptoms are breathlessness especially after sudden exertion or when exposed to temperature change and can be very similar to asthma, hyperventilation syndrome or pulmonary embolism. One of the defining characteristics of ''bird fanciers lung'' is that many medical tests will show a normal range of results and it will be identified by X-ray or CT scans showing physical changes to the lung structure (a ground glass appearance). If someone with BFL has been exposed to avian proteins they will see symptoms within 4–6 hours. Symptoms include chills, fever, breathlessness, non-productive cough and chest discomfort. In the chronic form there is usually anorexia, weight loss, extreme tiredness and progressive interstitial fibrosis which is the most disabling feature of the disease as this causes scarring on the lungs which reduces the lungs ability to move air in and out, and as a result sufferers have repeated chest infections and ultimately struggle to breathe. This condition is occasionally fatal. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bird fancier's lung」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
