Escherichia Coli productora de Nueva Delhi metalo-β-lactamasa en Colombia: Reporte de caso

Abstract

We report a case of infection by New Delhi metallo-β-lactamase (NDM)-producing Escherichia coli in a patient who developed a subcapsular hepatic abscess as a complication of laparoscopic cholecystectomy. NDM is an acquired carbapenemase Ambler class B, which confers resistance to all b-lactams except aztreonam, although there are reports of resistance to the latter. In Colombia, the first report of NDM-producing strains was made on isolates of Klebsiella pneumoniae in a neonatal intensive care unit in Bogota. There have since been reports of different strains, marking the first reported in the country of NDM-producing Escherichia coli.
