Results of the STRUCTURE analysis using the sequences of the seven MLST loci of the A. phagocytophilum strains (n = 383).

1K = number of clusters assumed. Each value of K (1–9) was run five independent times.2μ LnP(K) = mean of the estimated log-likelihood probability of the data for K.3s = standard deviation of the estimated log-likelihood probability of the data for K.4Ln’(K) = rate of change of the mean likelihood distribution.5|Ln″(K)| = absolute value of the second-order change of the mean likelihood distribution.6ΔK = mean |Ln″ (K)| divided by the standard deviation of L(K).7na = not applicable.8The solution most strongly supported is shown in bold.
