Electrophoresis of the amplified products from the lung mass with polymerase chain reaction (PCR) techniques. BAL was performed with 20 mL saline. The two types of gene fragments of Treponema pallidum (tpp47 and polA) acquired from bronchoalveolar lavage (BAL) and transbronchial biopsy (TBB) was amplified by PCR techniques. Both gene fragments were positive in samples from TBB, but not BAL
