Fig. 4

Minimum spanning net for distances on basis of a Kimura two-parameter (K2P) model corrected distance matrix from sequence alignment, showing the relations between the different A. phagocytophilum msp4 variants determined from this study. The corresponding hosts and an exemplary sequence for each variant are given in Additional file 2: Table S6. Variants highlighted in pink include cattle as host, and those highlighted in blue include dogs as host; variant m4-36 connecting the two parts of the net is indicated in green. Labelling is explained in “Data compilation and naming of sequences” section
