The phylogroup for each isolate was determined using ClermonTyping v1.4.0 with default settings for each isolate genome assembly. Phylogroups that are significantly associated with a specific host are indicated with an asterisck (*), as determined by maximum-likelihood ratio testing with a Benjamini-Hochberg adjusted P value of <0.05.
