Taxonomy/phylogeny:
 
About 25 different species have been described within the genus Treponema. There are different opinions among researchers about which should be regarded as separate species or only as subspecies of a certain species. T. paraluiscuniculi is very closely related to T. pallidum subsp. pallidum and T. pallidum subsp. pertenue. See the phylogenetic tree (Fig. 134:1). Some researchers regard the two latter as separate species.
Comment:Has not been cultivated in vitro. The disease cannot be transmitted to humans.
Reference(s): No. 54, 55

"Dear child has many names" (call it what you will...)

For a long time, Rhodococcus hoagii was refer­red to Rhodo­coccus equi on VetBact, because we experienced some resistance to the name that is now considered to be the correct one, i.e. Rhodococcus hoagii. Now you can find the bacterium in question under the correct name in VetBact, but you can also find the bacterium when searching for the old name.
