Results of the STRUCTURE analysis using the sequences of the seven MLST loci of the <i>A. phagocytophilum strains</i> (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.
