Abstract
AbstractThe polypeptides of seven strains of human treponemes were investigated by immunoblot analysis for their binding to the human placental collagens and laminin. Of the treponemal polypeptides, eleven polypeptides, 45‐kDa, 49‐kDa, and 62‐kDa polypeptides from T. pallidum ATCC 27087, a 48‐kDa polypeptide from T. phagedenis biotype Reiter, 51‐kDa and 53‐kDa polypeptides from T. vincentii ATCC 35580, 30‐kDa, 53‐kDa and 63‐kDa polypeptides from T. socranskii subsp. buccale ATCC 35534, a 52‐kDa polypeptide from T. denticola ATCC 35405, and a 53‐kDa polypeptide from T. denticola ATCC 33520 possessed an ability to bind to the laminin, type I, III, IV, or V collagen. An intermediate‐sized human oral isolate strain G7201 did not possess any laminin‐ or collagen‐binding polypeptides. Immunoelectron microscopy using intact treponemal cells with a single collagen‐binding polypeptide and the corresponding antisera demonstrated that the 51‐kDa and 53‐kDa polypeptides from T. vincentii, the 53‐kDa polypeptide from T. socranskii subsp. buccale ATCC 35534 and the 52‐kDa polypeptide from T. denticola ATCC 35405, were outer envelope proteins.
