Fig. 3

Neighbor-joining phylogeny of outbreak-associated isolates based on two cgMLST schemes, a 1827-cgMLST and b 1748-cgMLST, using CFSAN004336 for comparison. The trees are rooted at midpoint. The isolates that persisted in the milkshake maker until November 2015 and the clinical isolate collected in November 2015 are in blue color. The isolates collected in March and April 2015 were from ice cream processing facilities, not the hospital milkshake maker. The minimum, maximum and median of pairwise allele differences of outbreak isolates are indicated near the root
