Fig 2. Neighbor-joining tree based on the wgMLST analysis of K. pneumonia isolates from multiple batches of bean sprouts, using a pairwise ignore missing values approach.

Scale shows genetic distance. A batch was defined as bean sprout samples purchased on the same day from the same supermarket chain. wgMLST clusters are color coded (ID and MLST) as are store and batch of purchase. The date is the date of purchase of the sample. ID isolate identification number, MLST multilocus sequence typing, ST sequence type, S supermarket chain, R retailer.
