|Species/Subspecies:||Treponema pallidum subsp. pallidum|
|Categories:||Motile; primarily of interest in human medicin|
|Etymology:||Genus name: A turning thread|
Species epithet: Pale, pallid (referrs to the week Gram-staining)
Subspecies epithet: see Species epithet
|Significance:||T. pallidum subsp. pallidum is globally a very important human pathogen.
|Type Strain:||Not defined|
|Macromorphology (smell):||Cannot be cultivated contiuously in articial media or cell cultures. Is, therfore, propagated intratesicularly in rabbits.|
|Micromorphology:||Tightly coiled (0.1-0.18 x 6-20 µm). Has 2-4 periplasmic flagella at each end of the cell.|
|Gram +/Gram -:||G-|
|Spec. Char.:||Generation time: 24-30 h.|
|Disease:||Syphilis, which is a sexually transmitted disease.
|16S rRNA Seq.:|
||About 25 different species have been described within the genus Treponema. T. pallidum consists of two additional subspecies: pertenue and endemicum, which both are human patogens. Some researchers regard all these subspecies as separate species, although they are very closely related from a phylogenetic point of view. See the phylogenetic tree (Fig. 100:1). T. paraluiscuniculi is very closely related to T. pallidum.|
|Legislation:||Syphilis is classified in Sweden as a dangerous disease under the Communicable Diseases Act and shall be notified to the County Medical Officer in the County Council and to the Public Health Agency of Sweden.|
|The revised taxonomy of the mollicutes|
The revised taxonomy of mollicutes (mycoplasmas) has now been introduced on VetBact, which means that many of the species have been given new genus names or moved to another higher taxon.Published 2021-11-25. Read more...
