Budgerigar breeders' hypersensitivity pneumonitis presenting as chronic bronchitis with purulent sputum.
A 49-year-old woman complained of cough and a purulent sputum (about 40 ml/day). She kept budgerigars for a period of 30 years, she first noticed a productive cough 10 years previously. Her chest roentgenogram revealed a diffuse reticulonodular pattern. She was diagnosed as having a chronic type of budgerigar breeder's lung associated with chronic bronchitis. Peptostreptococcus anaerobius was cultured from her sputum, bronchoalveolar lavage fluid, as well as from droppings of her budgerigar. This is the second case of hypersensitivity pneumonitis presenting as chronic bronchitis with much sputum in Japan.
