Abstract

Borrelia turicatae (mouse virulent) and Treponema denticola, a small oral treponeme, formed right-handed helices as determined by scanning electron microscopy. Treponema pallidum (Nichols strain), Treponema paraluis-cuniculi, and two unidentified oral spirochetes displayed left-handed helices.
