In birds, some temperature control occurs in the respiratory system. [16] Water vapor heats cool air during inhalation in the trachea, and increases its humidity. [16] The resulting evaporative water loss varies greatly and depends on several factors including air sac pressure and the subsequent rate of air flow through the trachea.
Avian metapneumovirus (aMPV), also known as turkey rhinotracheitis or swollen head syndrome, [2] causes a variety of disease syndromes in birds, depending on the bird species and virus type (A, B, C or D). [3] First detected in 1978 in South Africa, the virus has spread all over the world except Australia. [4]
Bird fancier's lung (BFL), also known as bird breeder's lung, is a type of hypersensitivity pneumonitis.It can cause shortness of breath, fever, dry cough, chest pain, anorexia and weight loss, fatigue, and progressive pulmonary fibrosis (the most serious complication).
Texas avian flu outbreak spreads from cows to humans and chickens, but is ‘a very, very small part of the overall picture,’ state agriculture boss says This story was originally featured on ...
Highly pathogenic H5N1 avian influenza in a human appears to be far worse, killing over 50% of humans reported infected with the virus, although it is unknown how many cases (with milder symptoms) go unreported. In one case, a boy with H5N1 experienced diarrhea followed rapidly by a coma without developing respiratory or flu-like symptoms. [41]
Ibis (formerly The Ibis), subtitled the International Journal of Avian Science, is the peer-reviewed scientific journal of the British Ornithologists' Union. It was established in 1859. [1] Topics covered include ecology, conservation, behaviour, palaeontology, and taxonomy of birds.
The respiratory system of the common raven is no different. Flight is a unique feat among birds and provides them with many advantages in terms of food, predation, and movement. It is suggested that cardiovascular variables play a large part in avian flight and were naturally selected over time. [ 8 ]
M. avium and M. haemophilum infections in children form a distinct clinical entity, not associated with abnormalities of the immune system. M. avium typically causes unilateral swelling of one of the lymph nodes of the neck. This node is firm at the beginning, but a 'collar-stud' abscess is formed eventually, which is a characteristic blue ...
