Microplastics and antibiotic resistance genes as rising threats

Highlights

  • •
    MPs and ARGs build up in organisms, posing a risk to human health through the food chain.
  • •
    Plastic ball communities on MPs migrate and spread resistance genes via winds and currents.
  • •
    Human-impacted rivers alter microbial communities by influencing antibiotics and MPs flow.
  • •
    Controlling antibiotic use and improving waste treatment are key to reducing MP pollution.


Abstract

Microplastics (MPs) have been reported to be emerging contaminant of different environmental niches like air, soil, and water. When exposed to these environments, MPs interact with already existing antibiotics to create combined pollution that can harm organisms. MPs have garnered significant attention in academic circles due to their ability to adsorb antibiotics. This review article explores different dimensions of MPs, antibiotic resistance genes (ARGs), and the interplay between MPs, antibiotics, and antibiotic-resistant bacteria (ARB), emphasizing their interconnection with soil and water pollution. It also summarizes the mechanisms behind the interaction between antibiotics and MPs, detailing various physical and chemical interactions. Additionally, it outlines the pathways through which MPs and ARGs complexes spread, offering insights for future research and solutions to tackle compound pollution. The article concludes by providing targeted strategies to mitigate the environmental and public health risks posed by MP-associated ARG transmission, highlighting the need for integrated pollution control, advanced monitoring techniques, and stricter regulatory policies.

Xiaoyuan Han, an assistant professor in the Arthur A. Dugoni School of Dentistry at University of the Pacific, has received a prestigious National Institutes of Health grant for $702,000 to study oral cancer using artificial intelligence tools. Han, who teaches in the Department of Biomedical Sciences, was awarded a Support for Research Excellence-First Independent Research Award for four years. “Dr. Han’s work could help identify patients needing early care and increase our ability to provide personalized medical care to treat these patients,” said David Ojcius, assistant dean for research and co-chair of the Department of Biomedical Sciences. The award will provide opportunities for predental and predoctoral dental students to participate in research and collaborate with a multidisciplinary team to improve oral pathology diagnosis, Han said.
