Plastisphere-hosted viruses: A review of interactions, behavior, and effects
AI summary Read the abstract
This review examines how viruses attach to and thrive on microplastic surfaces in the environment, forming communities called the "plastisphere." These virus-laden microplastics can spread disease-causing agents through water and ecosystems, potentially reaching humans and posing public health risks that scientists are only beginning to understand.
Microbial communities, including bacteria, diatoms, and fungi, colonize plastic surfaces, forming biofilms known as the "plastisphere." Recent research has revealed that plastispheres also host a wide range of viruses, sparking interest in microbial ecology and virology. This shared habitat allows viruses to replicate, interact, infect, and spread, potentially impacting the environment and human health. Consequently, viruses attached to microplastics are now recognized to have broad effects on cellular and immune responses. However, the ecology and implications of viruses hosted in plastisphere habitats remain poorly understood, highlighting their fundamental importance as a subject of study. This review explores various pathways for virus attachment to plastispheres, factors influencing these interactions, their impacts within plastisphere and host-associated environments, and associated issues. It also summarizes current research and identifies knowledge gaps. We anticipate that this paper will help improve our predictive understanding of plastisphere viruses in natural settings and emphasizes the need for more research in real-world environments to advance the field.

Viruses in the era of microplastics and plastispheres: Analytical methods, advances and future directions
AI summary Read the abstract
This review examines how viruses interact with microplastics in the environment, including how viral particles attach to plastic surfaces and what this means for human and environmental health. Microplastics can carry viruses across water environments, and the biofilms that form on plastic surfaces create conditions for viral survival and gene transfer. These findings raise concerns that microplastics could serve as vehicles for spreading disease-causing viruses through water systems.
Microplastics and Nanoplastics as Carriers for Viral Transmission: Effects on Viral Properties, Infection, Immune Response, and Public Health
AI summary Read the abstract
This review examined how microplastics and nanoplastics can act as carriers for viruses, potentially influencing the spread of infectious diseases. Researchers found that plastic particles create a surface habitat called the plastisphere that promotes microbial growth and can serve as a reservoir for pathogens. The study suggests that micro- and nanoplastics may alter viral persistence, infection dynamics, and immune responses, though significant knowledge gaps remain about the real-world impact on public health.
The potential role of micro- and nanoplastics in the spread of viruses
AI summary Read the abstract
This review examines how micro- and nanoplastics may act as vehicles that amplify the spread and infectivity of pathogenic viruses in humans and animals, explaining that the plastisphere (the microbial community living on plastic surfaces) can preserve viruses and that plastics weaken the body's natural barrier tissues. The authors warn that plastic particles carrying viruses could increase infection risk and potentially even help viruses develop new variants, calling for urgent interdisciplinary research.
Environmental Risks of Plastisphere Viruses: Carrier Effects, Virus–Host Interactions, and Mechanisms of Resistance Dissemination
AI summary Read the abstract
Tiny plastic particles floating in water and soil quickly get coated with slimy biofilms that can attract and concentrate viruses, potentially turning microplastics into rafts that help spread disease-causing germs and antibiotic-resistant genes. This review pulls together existing research on the topic, and while the evidence so far is mostly based on indirect genetic analysis rather than direct proof, it raises an important flag: microplastic pollution might be doing more than just littering our environment—it could be helping harmful viruses travel and share dangerous traits. More hands-on lab testing is needed to confirm how big a real-world health risk
Microplastics as Vectors for Viral Transmission: Mechanisms, Influencing Factors, and Ecological-Health Risks
AI summary Read the abstract
Tiny plastic particles floating in the environment can stick to viruses and help them survive longer and spread more easily, which could increase the risk of getting sick. This review article summarizes what scientists have learned about how plastics and viruses interact, and why it matters, because many of us are now exposed to both microplastics and viruses at the same time, which could be worse for our immune systems than facing either threat alone. Understanding this problem better will help researchers figure out how to protect public health as plastic pollution continues to grow worldwide.
