Abstract:
Enterobacter hormaechei has emerged as a major bacterial pathogen implicated in neonatal sepsis, with several strains acquiring resistance to commonly used antibiotics. In this study, we provide the antibiotic resistance profile and genomic analysis of a multidrug-resistant E. hormaechei AH1-NIMR isolated from a neonate presenting with sepsis in a tertiary hospital in Lagos, Nigeria. E. hormaechei AH1-NIMR was resistant to ten of twelve antibiotics that were tested. Whole-genome sequencing and bioinformatics analysis revealed that the isolate harboured several antimicrobial resistance determinants, including plasmids IncHI2-1 and Col(pHAD28). Enhanced surveillance and screening for E. hormaechei in sepsis cases are recommended.
