Chlamydial classification and evolution

Classification Index (in sequential order).

[ Chlamydiae.com currently uses the Everett Andersen 1999 classification but is likely to also adopt the Stephens Horn Kuo Classification if it is widely accepted. Articles on the latter classification are particularly welcome. Authors are permitted to use either of these approved classifications provided that they are consistent throughout their article].
