Article Abstract:
The genospecies diversity of Lyme disease spirochetes in questing ticks on the subtropical island of Madeira was determined to be as great as that in Central Europe. This finding was remarkable given the fact that infection was scarce in ticks on the island. Local extinction of spirochete populations could be possible if there was infrequent transmission. However, repeated introductions via migrating birds or domestic animals from Europe could maintain this diversity.

Article Abstract:
The prevalence and genospecies of spirochetes present in rodent- and lizard-associated ticks was compared at a site where this spirochete frequently infects questing ticks for determining whether the Lyme disease spirochete Borrelia lusitaniae was associated with lizards. Genetic analysis confirmed that the spirochetes isolated from ticks feeding on lizards were members of the Borelia lusitaniae genespecies and resembled type strain PotiB2.

Article Abstract:
Vector ticks in various Central European sits for a related spirochete and its host association was determined in order to find whether the pathogenic variant of lyme disease spirochetes, isolate A14s, was perpetuated in a particular reservoir-relationship. Results showed that garden dormice serve as the main reservoir hosts of a novel genospecies, bornelia spielmani sp. nov., that cause lyme disease in people.
