Treponema pallidum is a motile, spirochaete bacteria that has subspecies that can cause treponemal diseases such as syphilis, pinta, bejel, and yaws. Syphilis is caused by the subspecies T. pallidum pallidum, pinta is caused by T. pallidum carateum, bejel is caused by T. pallidum endemicum, and Yaws is caused by T. pallidum pertenue. The four subspecies of T. pallidum are morphologically and serologically identical, however their course of action and transmission differs from one another. T. pallidum is a small bacterium that cannot be seen via Gram stain because it is too thin. However, it can be viewed by using dyes like Dieterle Stain (1). It can also be detected by serology tests. | Treponema pallidum is a motile, spirochaete bacteria that has subspecies that can cause treponemal diseases such as syphilis, pinta, bejel, and yaws.
