Principal Coordinates Analysis (PCoA) of 15 Polish larval cohorts. Three-dimensional plot showing the spatial relationships among samples studied based on Fst pairwise value matrix. The percentages of variance explained by the three main components are given on axes (47.02, 22.66, and 13.14, respectively). Green spheres refer to larval cohorts from outbreak 1 (orange font) and outbreak 2 (red font); black spheres refer to larval cohorts collected from wild boar. Circles are drawn to emphasize groupings of isolates from outbreaks 1 and 2
