a An unrooted maximum likelihood phylogenetic tree built using PHYLIP [61] and rooted using PATH-O-GEN [35]. Assigned clades are coloured accordingly: clade 1 = blue, clade 2 = red, clade 3 = gold and clade 4 = green. b The sampling locations of the isolates are plotted onto a map of New Zealand. Cattle and wildlife isolates are represented by circles and triangles, respectively. Isolates are coloured by their associated clade in the phylogenetic tree (a). Only isolates from clade 1 (blue) were selected for further analysis (white outline), faded isolates are those not selected. Isolate locations were jittered to avoid overlapping points. b The map underlying b was sourced from Google Maps, 2016 [62]
