Maximum likelihood phylogeny of the Icelandic nucleotide sequences for Borrelia afzelii, B. garinii and B. valaisiana strains that cluster within each representative genotype. The phylogeny was constructed using IQ-TREE and is midpoint rooted, with bootstrap values > 50 displayed at each relevant node. Sequences generated during this study are highlighted in purple for B. afzelii, cyan for B. garinii and red for B. valaisiana. The Icelandic B. afzelii sequence clusters with strains sequenced in central and eastern Europe whilst B. garinii and B. valaisiana sequences cluster with either central and eastern Europe or the UK
