Polymorphism patterns and prevalence of each pattern for APEC (n = 171), NMEC (n = 80), and UPEC (n = 148) for any polymorphism pattern that occurred greater than once. Polymorphism patterns A1, B2, C1, C4, D1, D3, and F2 are statistically significant between the subpathotypes (p < 0.05). Any polymorphism pattern that occurred fewer than two times was excluded from analysis
