Borrelia Burgdorferi. Lyme disease is caused by a number of different strains and species of Borrelia bacteria, generally Borrelia burgdorferi in the United States and Borrelia afzelii and Borrelia garinii in Europe. The Borrelia burgdorferi bacteria are named after scientist Willy Burgdorfer, who first identified the strain in the early 1980s.
1 Borrelia burgdorferi was named after its discoverer, Willy Burgdorfer. 2  Brugdorfer reported in 1982 that a spirochete, a type of bacteria, found in ticks of the Ixodes genus was probably responsible for Lyme disease. 3  A 90-million-year-old tick was discovered encased in amber in a vacant lot in New Jersey.owever, it is actually a disease caused by a bacterium called Borrelia burgdorferi. The bacteria is transmitted to humans via tick bites, so people associate ticks with Lyme disease. This way of disease transmission is a classic example of parasitology involving several organisms:
