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]
Burgdorfer gained worldwide recognition for his 1982 discovery of a tick-borne spirochete as the long-sought cause of Lyme disease and related disorders in the U.S. and Europe. [1] The agent was named after him — Borrelia burgdorferi .
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.
Eight are known to cause Lyme disease or Borreliosis. [6] The major Borrelia species causing Lyme disease are Borrelia burgdorferi, Borrelia afzelii, and Borrelia garinii. [23] All species that cause Lyme disease are referred to collectively as B. burgdorferi sensu lato, [10] while B. burgdorferi itself is specified as B. burgdorferi sensu stricto.
About 63,000 cases of Lyme disease were reported to the Centers for Disease Control and Prevention in 2022, according to a report released last month. That’s a nearly 70% jump in the number of ...
About 30,000 cases of Lyme disease in the U.S. are reported to the Centers for Disease Control and Prevention by state and local health departments each year. However, the CDC says that many more ...
In fact, in 2015, researchers from Mayo clinic discovered a new bacterial strain causing Lyme disease and decided to name it Borrelia Mayonii. So these Borrelia bacteria are all spirochetes which means that unlike other bacteria, they are long, thin, and spiral-shaped, and they spin or twist to move around.
Malawista and his colleagues initially hypothesized that Lyme disease was caused by a virus. [4] However, was later disproved in 1982 by microbiologist Willy Burgdorfer, who correctly identified the Borrelia burgdorferi bacterium as the cause of Lyme disease in Connecticut and the eastern United States.
