The sera from 2453 patients suffering from pneumonia were investigated for antibodies against the agent causing "Legionnaires' disease". A complement-fixing antigen developed in this institute was used for the screening of these sera, and the positive results were confirmed with the IF-test developed by CDC Atlanta. Antibodies were found in 23 Swiss patients. The clinical details from one of these patients are presented.
