Abstract

The differences between Escherichia coli strains associated with symptomatic and asymptomatic urinary tract infections (UTIs) remain to be properly determined. Here we examined the prevalence of plasmid types and bacteriocins, as well as genetic relatedness, in a defined collection of E. coli strains that cause UTIs. Comparative analysis identified a subgroup of strains with a high number of virulence genes (VGs) and microcins M/H47. We also identified associations between microcin genes, VGs, and specific plasmid types.

Cluster analysis based on VGs, bacteriocins, plasmid types, and sequence types created using Jaccard correlation and complete linkage. The dendrogram shows the RAPD profiles of each isolate. Green, purple, and red represent strains causing symptomatic UTI, ABU, and CA-ABU, respectively. Bacterial strains and their respective phylogenetic groups are also indicaated.
