They suggested that the organism might be a mycobacterium because it appeared as acid-fast rods in sections of lung tissue obtained from their patients. Serum samples from two of the patients showed high titers of antibody to the "Pittsburgh pneumonia agent" by the indirect fluorescent antibody (FA) technique. The "Pittsburgh pneumonia agent" described by Pasculle and associates (2) has been identified by Hébert and associates (3) as aLegionella-like bacterium identical to the TATLOCK bacterium (4) by...References1.
