Lyme borreliosis (LB), the most common vector-borne disease in Europe, North America and parts of Asia, is caused by the tick-bome Spirochete Borrelia species. In 1982, the bacterium that causes LB was first isolated by Willy Burgdorfer and colleagues from the hard tick Ixodes dammini collected On Long Island, N. Y. [1]. The isolate was subsequently identified as a new species of the genus Borrelia and was named Borrelia burgdorferi in 1984 [2]. In the past years classification of Lyme disease borreliae has been investigated intenSively. More than 20 Species have been identified within the genus Borrelia so far [3, 4]. These species are usually categorized into two major groups, the relapsing-fever borreliae and the Lyme borreliosis borreliae, that differ their ecological and genetic characteristics [3]....
