Severe Legionella and Histoplasma Pneumonia Acquired From Spring Water.

Legionnaires' disease and pulmonary histoplasmosis are important causes of community-acquired pneumonia.

Our case highlights a source of both legionella and histoplasmosis not previously reported. It demonstrates the value of taking a thorough history while recognizing non-traditional sources of both infections.
