Previous studies of Australian silver gulls demonstrated high levels of resistance to CIAs, particularly fluoroquinolone and extended-spectrum cephalosporins, among <i>E. coli</i> strains (carriage at 24% and 22%, respectively). This study aimed to identify and characterize strains from four distinct bird species inhabiting a common coastal environment, determine the frequency of carriage of CIA-resistant <i>E. coli</i> strains, and examine if these resistant clones andApplied and environmental microbiologye01610-20https://www.ebi.ac.uk/biostudies/studies/S-EPMC7531969biostudies-literatureImplications of Foraging and Interspecies Interactions of Birds for Carriage of Escherichia coli Strains Resistant to Critically Important Antimicrobials.PMC7531969Abraham SGunasekera SO'Dea MBarton MStegger MLaird TMukerji SJordan DDunlop JNAbraham RJfalseImplications of Foraging and Interspecies Interactions of Birds for Carriage of Escherichia coli Strains Resistant to Critically Important Antimicrobials.Globally, gulls have been associated with carriage of high levels of <i>Escherichia coli</i> strains resistant to critically important antimicrobials (CIAs), a major concern, as these antimicrobials are the sole alternative or one among only a few alternatives available to treat severe life-threatening infections in humans.
