Italian study finds antibiotic resistance genes in the world's oceans

According to the findings of an Italian-led project that analysed seawater samples from around the world, genes linked to resistance to antibiotics are present in multiple?ocean areas, including remote waters.

The SeA ?Care project found ?antibiotic-resistance ?genes in the Mediterranean, Atlantic, Arctic and other regions, with higher concentrations detected near busy shipping routes and densely populated coastal areas.

Researchers said that the results show oceans are a global reservoir of pollution from land. They carry genetic traces of antibiotic use and urban discharge far away from their source.

Researchers added that this could facilitate their spread to remote communities.

The study was presented on Monday in Rome at a forum hosted by the Italian?National Health Institute. (ISS) on ocean and human healthcare. It also detected microplastics and PFAS "forever chemical" as well as traces of 'SARS-CoV-2 DNA in remote areas and open ocean waters.

Andrea Piccioli, ISS Director-General, said that protecting human health in the 21st century means protecting the oceans and seas. She added that pollution released into the atmosphere is redistributed worldwide through the water, food, and climate systems.

SeA 'Care, an initiative led by Italy, links the environment and human health. The system brings together institutions such as the Italian Navy, ISS and international research centres in order to create a global monitoring?system.

The project uses existing routes for collecting samples and scientific networks during routine missions to reduce costs and impact on the environment.

In the first three years of its existence, over 4,000 samples of?seawater were collected in 140 locations across the Mediterranean Sea, Atlantic Ocean, Pacific Ocean, Arctic Ocean and Indian Ocean.

Scientists claim that the project shows 'how oceans can be used as an early warning system to detect global health risks. It supports policies aimed at combating pollution, climate changes and emerging threats for human health. (Reporting and editing by Crispian B. Balmer, with Emilio Parodi)
