Aim: Extended-spectrum β-lactamase-producing (ESBL) Escherichia coli are a public threat worldwide. This study aimed at analyzing the genomic and functional attributes of nine ESBLs taken from rectal swabs. Materials & methods: Samples were isolated from patients admitted for gastrointestinal and urological procedures at the University Medical Center-Rizk Hospital (UMCRH) in Lebanon. Illumina paired-end libraries were prepared and sequenced. Results: The isolates were distributed into five lineages: ST131, ST648, ST405, ST73 and ST38, and harbored bla OXA-1, bla TEM-1B, bla TEM-1C and aac(6′)Ib-cr. ST131 isolates were carriers of stx2 converting I phage. Conclusion: This is the first comprehensive genomic analysis performed on ESBLs in Lebanon.
