[Severe pneumonia from psittacosis in a bird-keeper].

A 67-year-old man was admitted due to severe pneumonia. Initially he was treated with beta-lactam antibiotics and oxygen. However, he developed respiratory failure and was transferred to the intensive-care unit for mechanical ventilation. He was a bird-keeper who collected many species of exotic birds, including parrots. The diagnosis psittacosis (parrot fever) was confirmed serologically and by PCR on bronchoalveolar lavage fluid. PCR techniques lead to rapid diagnosis which allows for early treatment. The initial treatment of atypical pneumonia with ciprofloxacin failed. After the patient was treated with doxycycline 200 mg i.v. his clinical condition improved and he was cured. The patient was discharged from intensive care after 10 days when acute respiratory-distress syndrome and pericarditis had resolved. Psittacosis is seen sporadically in the Netherlands. It may be encountered more frequently among patients who have had contact with birds and should be considered in the differential diagnosis of atypical pneumonia.
