|
Only two differens species have been descibed within the genus Paeniclostridium. P. sordellii is closely related toP. ghonii, for which the genus affiliation alse has been changed. Paeniclostridium is, as the namy implies, closely related to the genus Clostridium. Please note that the name of the bacterium in the tree (Fig. 31:2) is still Clostridium sordellii. | ||||||||
