Occurrence of carbapenemase-producing bacteria in coastal recreational waters.

摘要: The spread of carbapenemase-producing Gram-negative rods is an emerging global problem. Although most infections due to carbapenemase producers are limited healthcare institutions, reports the occurrence clinically relevant in sewage and polluted rivers increasingly frequent. Polluted flowing oceans may contaminate coastal waters with multidrug-resistant bacteria, potentially threatening safety recreational activities these locations. Here we assessed water from touristic beaches located Rio de Janeiro, Brazil, showing distinct pollution patterns. presence enterobacteria was noted, including predominantly environmental genus Kluyvera spp., producing either Klebsiella pneumoniae (KPC) or Guyana extended-spectrum (GES)-type carbapenemases often associated quinolone resistance determinants. An Aeromonas sp. harbouring blaKPC qnrS also observed. These findings strengthen role aquatic matrices as reservoirs vectors antimicrobial-resistant potential favour threats throughout community.
