  1. Distribution of antibiotic resistance of uropathogenic E. coli (n = 155) among different sequence types. The p values were calculated by comparing individual STswith each other. The table correlates different traits in vertical columns among different sequence types. The percentages were calculated with reference to total number of sequence types
