Veterinary bacteriology: information about important bacteria
|Etymology:||Genus name: A turning thread|
Species epithet: From a rabbit with a syphilis like disease
|Significance:||[Of minor importance]|
|Alternative Species Name(s):||Treponema cuniculi|
|Type Strain:||Not defined, but Cuniculi A is a reference strain.|
|Macromorphology (smell):||Cannot be cultivated in articial media and is, therfore, propagated intratesicularly in rabbits.|
|Gram +/Gram -:|
|Disease:||Rabbit venereal syphilis or venereal rabbit spirochetosis.
|Diagnostics:||Dark field microscopy of the lesions are used for diagnostics.|
|16S rRNA Seq.:|
||About 30 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|
|New names of bacterial phyla|
The taxonomic category phylum was previously not regulated by the International Code of Nomenclature of Prokaryotes (ICNP), but now this has changed and it was decided to revise the names of bacterial phyla. All phyla must be written in italics (which has been done on VetBact also before) and have the ending -ota.Published 2023-03-01. Read more...
|The taxonomy of chlamydias|
Species within the family Chlamydiaceae were previously divided into two genera Chlamydia and Chlamydophila. However, the differences between these two genera were not that great and many research groups have not accepted this division. Therefore, the genus Chlamydophila has been returned to the genus Chlamydia and this change has now been incorporated in VetBactPublished 2023-03-15. Read more...
