Rivers Becoming 'Reservoirs of Disease'
vendredi 12 juillet 2024, 21:22 , par Slashdot
Scientists say 'a reservoir of disease' is being created after discovering bacteria that naturally occur in rivers are becoming resistant to antibiotics due to the impact of sewage. From a report: Researchers at the University of Suffolk said bacterial strains found on the non-tidal section of the River Deben in Suffolk had acquired resistance by exchanging DNA with antibiotic resistant E. coli. Some bacteria have become resistant to the antibiotic carbapenem, which is used as the last line of defence in fighting infections already resistant to traditional antibiotics. Dr Nick Tucker, a microbiologist leading the research, described the discovery as 'particularly worrying.'
'Organisms that are currently low risk are being mixed with pathogenic organisms from sewage,' he said. 'We're needlessly adding pathogenic and virulence genes to bacteria found in the environment, and that could be creating a reservoir of disease.' The team has been working closely with citizen scientists from the Deben Climate Centre, who have been taking water samples for two years. They have also been working with scientists at the government's CEFAS laboratories, who have helped identify the new strains that are being screened for their resistance to six of the most commonly-used antibiotics. The River Deben rises in Debenham, Suffolk, before flowing through Woodbridge and down to the North Sea. Read more of this story at Slashdot.
