In the last years, the rapid spread in anthropized ecosystems of pathogens which are resistant to carbapenem antibiotics has raised great concern. In this study, KPC-producing Klebsiella pneumoniae was found in the River Lambro in June 2019, whereas KPC-producing Klebsiella oxytoca and Citrobacter braakii were identified in untreated wastewaters. Susceptibility profiles indicated resistance to imipenem, ertapenem and meropenem. Different carbapenamase genes (blaKPC, blaNDM, blaVIM, blaOXA-48) were also found in the River Lambro, although not associated to living bacteria. The presence of a wide set of carbapenemase genes and resistant pathogens show that river sediments could act as a reservoir of antibiotic resistance potentially threatening human health.
