Abstract
Background During the past years an E coli clonal lineage ST131 has emerged explosively, causing predominantly communityonset antimicrobial resistant infections. E coli ST131 has been shown to harbor a number of virulence and resistance genes and is now recognized for its ability to cause potentially severe infections in many parts of the developing world, implying public health measures in attempt to control infection.
Highlights
During the past years an E coli clonal lineage ST131 has emerged explosively, causing predominantly communityonset antimicrobial resistant infections
By pabB PCR, we identified 22 (26%) E coli isolates belonging to the O25b-ST131 clonal lineage
Among patients with blood stream infections (BSI) caused by resistant E coli, the in-hospital mortality was similar in patients infected with strains carrying the ST131 clonal lineage (3; 14%) versus non ST131 (10; 17%) (p=0.921)
