Lyme disease. 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 ...
Chronic Lyme disease ( CLD) is the name used by some people with non-specific symptoms, such as fatigue, muscle pain, and cognitive dysfunction to refer to their condition, even if there is no evidence that they had Lyme disease. [2] [3] Both the label and the belief that these people's symptoms are caused by this particular infection are ...
Lyme disease, or borreliosis, is caused by spirochetal bacteria from the genus Borrelia, [1] which has 52 known species. Three species ( Borrelia garinii, Borrelia afzelii, and Borrelia burgdorferi s.s.) are the main causative agents of the disease in humans, [2] while a number of others have been implicated as possibly pathogenic.
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]
The incidence of Lyme disease is tied to many factors including climate. Certain regions worldwide supply the proper conditions for ticks to flourish. Ticks like habitats with at least 85% humidity and can only practice host questing at temperatures greater than 7 °C (45 °F). [ 7] In order to find microclimates that are suitable ticks will ...
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 complex currently comprises 20 ...
Allen Caruthers Steere is an American rheumatologist. He is a professor of rheumatology at Harvard University and previously at Tufts University and Yale University.Steere and his mentor, Stephen Malawista of Yale University, are credited with discovering and naming Lyme disease, and he has published almost 300 scholarly articles on Lyme disease during his more than 40 years of studies of this ...
Erythema migrans or erythema chronicum migrans is an expanding rash often seen in the early stage of Lyme disease, and can also (but less commonly) be caused by southern tick-associated rash illness (STARI). [ 1][ 2] It can appear anywhere from one day to one month after a tick bite. This rash does not represent an allergic reaction to the bite ...
