A helical shaped spirochete with a flexible cell wall containing inner and outer membrane involved in Lyme disease in humans.


Borrelia burgdorferi has a size of at least 1 micrometer wide and 10-25 micrometer long showing unique structural features in which flagella is located inside the periplasm stuck between inner and outer cell membranes where interaction of flagella and cell cylinder travels through viscous fluids and this adaption is the ability of this bacterium to journey through the tissue of the host causing it to be more invasive.

Borrelia burgdorferi has a distinct mode of movement by means of axial filaments that mostly found in the intestinal tracts and oral cavity of humans. It contains one large linear chromosome with approximately 853 coding genes used for basic functions like transcription, DNA replication, translation and metabolisms. It has been known to be unique due to its high number of plasmids where most of the bacteria lack the complete set of plasmids to successfully infect the host.

Borrelia burgdorferi associated with Lyme diseases from the bite of infected blacklegged ticks which occurs after 24hrs-48hrs after sucking where it penetrates into the bloodstream that primarily affected the skin, myocardium, nerve tissues and synovial fluid. Its symptoms manifested including headache, fever, fatigue and skin rashes and if left untreated leads toheart and joint infections.
