Researchers can make bacteria more resistant to antibiotics, according to researchers

Bacteria It is exposed to Microplastics It can become resistant to antibiotics, according to a new study. American researchers studied how the bacteria exposed to different concentrations of fine plastic, pPlastic pieces from equeñOS are less than five millimeters Everywhere in the environment and the human body.

They used Escherichia coli (E. Coli)Common bacteria that can contain pathogens and It causes infections such as poisoning Food “plastic materials provide a surface that bacteria and colonialism adhere to,” Explanation in a statement Nella Gross, PhD at Boston University (USA) and the main author of the study .

When they are on the surface, Bacteria creates a protective layer called biological membranesAfter that, the researchers tested four common antibiotics. When the biofil film and the microscopic gardens were combined, the medicines did not succeed, according to the conclusions published on Tuesday in the magazine. Applied and environmental microbiology.

“We discovered these vital membranes MicroPlasticsCompared to other surfaces such as glass, it is stronger and thick, like a house that has a lot of isolation, “added Gross. Among the various plastic materials that have been analyzedThe authors wrote: “In particular, polystyrene had the most important influence on the development of resistance,” the authors wrote.

High risk to public health

World Health Organization (from) It considers that antimicrobial resistance (RAM) is one of the main threats to global public health. RAM makes the treatment of bacteria, viruses, fungi and parasites difficult and threatens human health, animals and plants. In 2020 there were more than 865,000 infections Resistance to antibiotics in European countries, and more than 35,000 people lost their lives because of them.

“The fact that there are microblasts Around us, and more in poor places where sanitation can be limited, it is an amazing part of this observation. This may be a greater risk In disadvantaged societies, only to emphasize the need for more monitoring and deeper knowledge of the interactions (flour plastic and bacteria), adding.

Previous investigations showed that the forcibly displaced residents manage a A greater risk of resistance To antimicrobials due to the living conditions in the acquired camps and barriers in front of health systems.

Experts request more research on this topic“The study is under control,” said Chilba Chocke, a professor at the University of Pleimouth (UK), adding that you should be careful when interpreting the results.

“It is a laboratory study in it Use E. coli And four antibiotics in control conditions, which do not completely complicate the real world. More search is needed To assess whether these effects are transferred to human infections or environmental environments, “Chokshi added, which was not involved in the study.
