Lyme disease, also known as Lyme borreliosis, is a tick-borne disease caused by species of Borrelia bacteria, transmitted by blood-feeding ticks in the genus Ixodes. [4] [9] [10] The most common sign of infection is an expanding red rash, known as erythema migrans (EM), which appears at the site of the tick bite about a week afterwards. [1]
The diagnosis of Lyme disease is clinical, based on signs and symptoms and on a history of exposure to infected ticks. Physicians look to blood tests to support their diagnosis. Usually blood testing for Lyme is doneNow the diagnosis of Lyme disease is usually made by looking at antibodies against Borrelia proteins. via a test called a Western ...
Borrelia burgdorferi is a bacterial species of the spirochete class in the genus Borrelia, and is one of the causative agents of Lyme disease in humans. [ 1 ] [ 2 ] Along with a few similar genospecies, some of which also cause Lyme disease, it makes up the species complex of Borrelia burgdorferi sensu lato .
The bacterium that causes Lyme is Borrelia burgdorferi, a spirochete. [15] A number of other bacteria are transmitted by ticks, such as Babesia (very important in the context of cattle), Ehrlichia (causes ehrlichiosis), Anaplasma (causes anaplasmosis), Rickettsia (causes Rocky Mountain Spotted Fever), and many others.

Several studies have failed to detect Borrelia burgdorferi, which is the causative agent of Lyme disease, in patients from the southern United States. [ 5 ] [ 6 ] This disease may be caused by the related bacterium Borrelia lonestari , [ 7 ] [ 8 ] which is a spirochete first isolated in culture in 2004. [ 9 ]
"Erythema migrans is the only manifestation of Lyme disease in the United States that is sufficiently distinctive to allow clinical diagnosis in the absence of laboratory confirmation." [8] [9] Often, but not always, mentions of a target lesion (bull's-eye lesion) are talking about erythema migrans. However, the appearance of erythema migrans ...
The bacterium Borrelia burgdorferi, which causes Lyme Disease, is transmitted by ticks and members of the bacterial genus Rickettsia are transmitted by lice. For example, the human body louse transmits the bacterium Rickettsia prowazekii which causes epidemic typhus.
Borrelia is a genus of bacteria of the spirochete phylum. [1] Several species cause Lyme disease , also called Lyme borreliosis, a zoonotic , vector-borne disease transmitted by ticks . Other species of Borrelia cause relapsing fever , and are transmitted by ticks or lice , depending on the species of bacteria. [ 2 ]
