relictum (P_SGS1 and P_GRW11) differed significantly from each other and between countries (with Spain excluded as these lineages could not be identified in mixed infections with the newly-designed primers), and almost significantly between sampling periods, but seasonality differences between countries were not detected (GLM Chisq test: Lineage: P < 0.001; Country: P < 0.001; Sampling Period: P = 0.06; Lineage versus Sampling Period: P = 0.885).
