Network of ticks, vertebrate hosts (excluding domestic animals) and TBP. Networks were calculated from a compilation of published data spanning the period 1990–2014 on taxonomic associations among these organisms in the western Palearctic. A total of 15,342 records were summarized in 1022 unique different combinations of ticks, vertebrates and pathogens. The nodes and the edges of the networks were colored according to its modularity (see Additional file 1). For example, the nodes in yellow are the cluster of taxa represented by the tick Ixodes ricinus, three secondary tick species (Rhipicephalus bursa, Dermacentor reticulatus and I. persulcatus), their hosts, and the pathogens these ticks and vertebrates contribute to circulate. The size of each node is proportional to its Node Betweenness Centrality (NBC) and the size of the label is proportional to its PageRank (PR) (see Additional file 1)
