Species

Treponema is a bacterial genus. The major species is Treponema pallidum, whose subspecies are responsible for diseases such as syphilis and yaws.

The species Treponema hyodysenteriae and Treponema innocens have been reclassified into Serpulina hyodysenteriae and Serpulina innocens.[1]

In the early 2000s they have again been reclassified into the family Brachyspiraceae.

Treponema paraluiscuniculi is associated with syphilis in rabbits.[2]

Treponema carateum is the cause of pinta.[3]

Phylogeny[edit]

The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) [4] and National Center for Biotechnology Information (NCBI)[5] and the phylogeny is based on 16S rRNA-based LTP release 111 by 'The All-Species Living Tree' Project [6]
