Dangerous bacteria lurk in hospital sink drains, despite rigorous cleaning

Researchers from Spain sampled sink drains from different wards in a single modern university hospital where state-of-the-art cleaning protocols are adhered to. Through culturing and DNA barcoding, they found 67 species of bacteria. These included Klebsiella, Enterobacter, and Pseudomonas aeruginosa, notorious for their potential to cause healthcare-associated infections. Several strains detected proved resistant to modern antibiotics, including cephalosporins and carbapenems. Sink drains thus appear to function as reservoirs for known and emerging pathogens of concern.
