Drug-resistant bacteria: Sewage-treatment plants described as giant ‘mixing vessels’ after scientists discover mutated microbes in British river

an image of bacteriaSuperbugs resistant to some of the most powerful antibiotics in the medical arsenal have been found for the first time in a British river – with scientists pinpointing a local sewage-treatment plant as the most likely source.

Scientists discovered the drug-resistant bacteria in sediment samples taken downstream of the sewerage plant on the River Sowe near Coventry. The microbes contained mutated genes that confer resistance to the latest generation of antibiotics.

The researchers believe the discovery shows how antibiotic resistance has become widespread in the environment, with sewage-treatment plants now acting as giant “mixing vessels” where antibiotic resistance can spread between different microbes.

A study found that a wide range of microbes living in the river had acquired a genetic mutation that is known to provide resistance to third-generation cephalosporins, a class of antibiotics used widely to treat meningitis, blood infections and other hospital-acquired infections.
