Nanoplastics can make E. Coli Infections Worse:

Nanoplastics can make E. Coli Infections Worse: Study

vishal pathaniya

June 06, 2025

A new study from the University of Illinois, Urbana-Champaign, reveals that nanoplastics not only pose a risk on their own but also enhance the virulence of pathogens.

  • Pathogens are disease-causing organisms.

About Nanoplastics

    • Nanoplastics are tiny particles, as small as smoke particles.
    • They are found everywhere—from mountain peaks to deep ocean trenches, and even inside human tissues and newborns.
    • They can damage cells and genetic material and now appear to increase the pathogenicity of microbes.
  • Sources
  • Primary: Manufactured nanoplastics for consumer and industrial use. 
  • Secondary: Breakage of large plastic items into smaller ones due to chemical degradation, weathering, UV exposure. 

 

About E. coli 

  • E. coli stands for Escherichia coli,  is a type of bacteria commonly found in the intestines of humans and animals.

Key Highlights of the Study

  • Nanoplastics can make E. coli more dangerous.
    • Mechanism: E. coli naturally has negatively charged outer membranes, which attract positively charged nanoplastics.
    • Upon Interaction, it experiences stress and responds by producing more Shiga-like toxins—the very toxins that make it harmful to humans.

Significance of Study:

  • This study suggests nanoplastics aren’t just pollutants—they can change how bacteria behave and increase public health risks
