Extraintestinal pathogenic Escherichia coli as a cause of invasive nonurinary infections.
Multiple Escherichia coli isolates from four adults with extraintestinal infections underwent molecular phylotyping and virulence profiling. A patient with secondary peritonitis had two low-virulence E. coli strains from phylogenetic groups A and D. In contrast, three patients with invasive extraurinary infections (septic arthritis/pyomyositis, nontraumatic meningitis/hematogenous osteomyelitis, and pneumonia) each had a single high-virulence phylogenetic group B2 strain resembling typical isolates causing urinary infection and/or sepsis, i.e., extraintestinal pathogenic E. coli.
