Figure 1.
Multilocus sequence type (MLST)-based minimal spanning tree of 152 Streptococcus uberis isolated from bovine mastitis milk during 2017 in Switzerland. The tree was calculated and generated using the goeBURST full MST algorithm in Phyloviz 2.0. Node sizes reflect the number of isolates with specific MLST profile. Numbers within the nodes indicate the ST. Node colors refer to types of mastitis: acute (red), subclinical (green), chronic (orange), unspecified mastitis (blue). Numbers on lines indicate locus variants between adjacent nodes. Grey shadows indicate STs belonging to clonal complex (CC)5.
