The Ixodes ricinus complex is composed of 14 species distributed worldwide. Some members of this complex are involved in the transmission of a number of diseases to animals and humans, in particular Lyme borreliosis, tick-borne encephalitis, ehrlichiosis and babesiosis. While the phylogenetic relationships between species of the I. ricinus complex have been investigated in the past,...

Diversity within Borrelia burgdorferi sensu lato genospecies in Switzerland by recA gene sequence

Casati, Simona ; Bernasconi, Marco V. ; Gern, Lise ; Piffaretti, Jean-Claude

In: FEMS Microbiology Letters, 2004, vol. 238, p. 115-123

A total of 874 Ixodes ricinus ticks were collected in Switzerland to investigate the genetic diversity of the Borrelia population. We integrated to the RT-PCR method the DNA sequence analysis of a 162-bp fragment of the recA gene. Five genospecies were detected: Borrelia afzelii, Borrelia burgdorferi s.s., Borrelia garinii, Borrelia valaisiana, and...
