Yet Another Reason to Be Terrified of Plastic

Is microplastic now a major source of antibiotic resistance spread? The answer could be yes

Imagine you are enjoying a nice summer day at the beach. The water is crystal clear, the sun is shining, and you are relaxed. As you take a closer look at the sand, you notice that it is covered in tiny pieces of plastic. You may think of them as harmless, but science suggests otherwise.

Microplastic could be a silent carrier of antibiotic resistance genes

A recent study has found that microplastic could be a significant source of antibiotic resistance genes (ARGs) in the environment. ARGs are genes that give bacteria the ability to resist antibiotics. This is a major concern, as antibiotic resistance is one of the biggest threats to global health. (1)

The study, which was published in the journal Environmental Science & Technology, found that microplastic collected from beaches and wastewater treatment plants contained a wide variety of ARGs. The researchers also found that the ARGs were able to transfer from microplastic to bacteria in the environment. (2)

This study adds to the growing body of evidence that microplastic is a major threat to human health. Not only is it a physical hazard, but it can also carry harmful chemicals and microbes. (3)

How does microplastic spread antibiotic resistance?

Microplastic can spread antibiotic resistance in several ways. First, it can act as a physical carrier of ARGs. When bacteria attach to microplastic, they can transfer their ARGs to the plastic. The microplastic can then transport the ARGs to other environments, where they can be taken up by other bacteria. (1)

Second, microplastic can leach chemicals that promote the development of antibiotic resistance. These chemicals can damage the DNA of bacteria, making them more likely to acquire ARGs. (2)

Finally, microplastic can create environments that are favorable for the growth of antibiotic-resistant bacteria. These environments are often characterized by high levels of pollution and low levels of oxygen. (3)

What can be done to reduce the spread of microplastic?

There are several things that can be done to reduce the spread of microplastic. First, we can reduce our use of plastic products. Second, we can properly dispose of plastic waste. Third, we can support policies that reduce the production and use of microplastic. (1)

By taking these steps, we can help to protect human health and the environment from the harmful effects of microplastic.
