Veterinary bacteriology: information about important bacteria
|Etymology:||Genus name: named after the French bacteriologist Amédée Borrel (1867-1936).|
Species epithet: named after Willy Burgdorfer, who in 1981 found spirochetes in ticks from the area around Old Lyme (Connecticut, USA) and associated the finding to the disease (Lyme disease).
|Type Strain:||B31 = ATCC 35210|
||Borrelia spp. have a planar flat-wave morphology. B. burgdorferi is 0.33 x 10-20 µm in size with 3-10 waves. Has 7-11 periplasmic flagella (endoflagella or axial filaments) at each cell end and is very motile.|
|Gram +/Gram -:||G-, difficult to stain|
||Tick borne, in Sweden usually by Ixodes ricinus but can most likely also be transferred by Ixodes hexagonus|
|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.|
|Comment:||The disease was first described in 1975.|
|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...
