INTRODUCTION: Borrelia miyamotoi is a tick-borne pathogen belonging to the relapsing fever group. It had not been reported from Spain, but its wide distribution and the presence of the tick-vector (Ixodes ricinus) made us suspect its circulation. The aim of this study was to investigate the presence of Borrelia spp. in I. ricinus in Spain.
METHODS: A total of 652 I. ricinus nymphs collected in northern Spain were processed. The DNA was extracted using incubations with ammonium hydroxide. Borrelia spp. DNA was amplified using Borrelia-specific PCR assays (glpQ, 16S rRNA and flagellin genes).
RESULTS: B. miyamotoi was amplified in 4 specimens, and Borrelia burgdorferi sensu lato in 27 (8 Borrelia afzelii, 7 Borrelia garinii, 8 Borrelia lusitaniae, 3 Borrelia valaisiana and 1 B. burgdorferi sensu stricto).
CONCLUSION: B. miyamotoi should be considered in the differential diagnoses of patients with confirmed or suspected tick-bite in Spanish endemic areas for Lyme disease.
