Genome Sequences of Seven Clade B2 Escherichia coli Strains Associated with Recurrent Urinary Tract Infections in Postmenopausal Women.

We report the genome sequences of seven recently isolated Escherichia coli strains from symptomatic postmenopausal women with a history of recurrent urinary tract infections. We have observed rapid laboratory evolution of strains after isolation. These strains were minimally passaged before analysis to prevent changes during culturing.
