"Pittsburgh Pneumonia Agent": A Bacterium Phenotypically Similar to Legionella pneumophila and Identical to the TATLOCK Bacterium

Abstract
The Pittsburgh pneumonia agent isolated by Pasculle and co-workers from human lung tissue was cultured on artificial media and characterized. The Pittsburgh bacterium and the TATLOCK and HEBA bacteria have identical cultural, biochemical and antigenic characteristics. They have the same cellular fatty-acid composition, and DNA relatedness indicates that they belong to the same species.
