Veterinary bacteriology: information about important bacteria
|Etymology:||Genus name: named after the French bacteriologist Amédée Borrel.|
Species epithet: named after the Swedish dermatologist Arvid Afzelius (1857-1923), who first described "erythema migrans" at a dermatology congress in Stockholm in 1909.
|Alternative Species Name(s):||Borrelia burgdorferi sensu lato|
|Type Strain:||VS461 = ATCC 51567|
|Micromorphology:||Spiral shaped (0.2-0.3 x 20-30 µm), motile and has endoflagella (axial filament)|
|Gram +/Gram -:||G-, difficult to stain|
||Ixodes sp. (tick)|
|Disease:||Lyme borreliosis (Lyme disease)
|16S rRNA Seq.:|
||About 40 different species have been described within the genus Borrelia and about half of these (among others B. afzelii and B. garinii ave been affiliated to B. burgdorferi sensu lato, which means B. burgdorferi in a wider sense. B. burgdorferi sensu stricto, in this context, means only the species B. burgdorferi.|
|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...
