What are the incidences, antibiotic susceptibilities, and O serotypes of extraintestinal invasive infections in US communities?In this cohort study using population-based data from more than 7.2 million people, there were 1345 invasive infections; incidence rates were higher among older compared with younger populations and most frequently associated with infections of the urinary tract. Nearly 14% of infections were caused by extended-spectrum β-lactamase–producing , and O25B was the most prevalent O serotype.These findings suggest there is a significant burden of invasive infections in US communities, and high rates of antimicrobial resistance in this pathogen warrant continued prevention efforts.
