No evidence of Borrelia mayonii in an endemic area for Lyme borreliosis in France

Abstract

Abstract Background Borrelia mayonii is currently the latest species belonging to the Borrelia burgdorferi (sensu lato) complex to be discovered. Interestingly it is involved in human pathology causing a high fever. We looked for its presence in post- tick bite febrile patients as well as in Ixodes ricinus ticks in an endemic area of France. Results After ensuring that our molecular technics correctly detected B. mayonii, 575 patients and 3,122 Ixodes ricinus nymphs were tested. Neither B. mayonii nor another species of the B. burgdorferi (s.l.) complex previously not reported in Europe has been identified. Conclusions For now, B. mayonii seems to be an epiphenomenon. However, its discovery broadens the etiology of post-Ixodes bite febrile syndromes.
