|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 taxa within the classification category phylum|
During October 2021, an article was published by A. Oren och G.M. Garrity, in which new names are proposed for a number of taxa within the classification category phylum. This has resulted in many discussions in social media about whether it was really necessary to make these changes, which have created confusion among microbiologists and other professionals who come into contact with bacteriology.Published 2022-09-28.
