Escherichia coli causing bloodstream infections in Mexican paediatric patients: molecular typing, antimicrobial resistance, virulence factors, and clinical features
Both commensal and pathogenic E. coli strains cause BSIs in paediatric patients with underlying diseases. Resistance to 3GCs and 4GCs is mainly mediated by CTX-M, hence treatment with carbapenems was used. Infection-related deaths were more frequent in patients infected by pathogenic phylogroups, where papC, sat, and irp2 were more prevalent. High-risk clones were widely distributed among isolates.
