Nocardiosis in two Pesquet's parrots (Psittrichas fulgidus).
Nocardiosis is described in two Pesquet's parrots (Psittrichas fulgidus). Granulomatous lesions containing numerous branching, filamentous, acid-fast, gram- and methenamine silver-positive organisms were observed in sections of lung from both parrots, suggesting an oral-respiratory portal of entry. Thyroid follicular hyperplasia and osteoporosis were observed in one parrot, suggesting the presence of an underlying nutritional or metabolic defect.
