(1) Clinical symptoms
Chickens usually have respiratory diseases for a long time before airbag inflammation occurs. The main manifestations are cough and runny nose. Chickens are not serious when they are quiet, but when they are driven away, they keep coughing and running nose, one after another, and even become a piece. Sick chickens have difficulty breathing, and some chickens have red eyes, tears and runny noses.
(2) Pathological anatomy
In the early stage of pneumonia, there are yellow sticky pus-like substances or yellow cheese-like substances or white sticky foam-like substances in the abdominal air sac (this is caused by mixed infection of mycoplasma), and the chest air sac can be thickened in the middle and late stage, and there are yellow cheese-like substances between the air sac and the chest wall. Myocardial hemorrhage and subcutaneous fat are scattered at the bleeding point, pancreatic hemorrhage and necrosis, needle-like hemorrhage in thymus, and severe bleeding in the whole trachea (commonly known as red trachea).
(3) Etiological analysis
Pneumocystis is caused by mixed infection of mycoplasma, chlamydia, Escherichia coli and avian influenza. Bird flu is the chief culprit in the whole process. Therefore, influenza is the key factor leading to pneumonia. In the clinical treatment of pulmonary cysticercosis, the treatment of influenza and other viral diseases can not be ignored at first.
