Li W, Zhu Z, Fang X, Wang X, Chu W, Gong H, Yan M. Polyvinyl chloride microplastics facilitated the transmission of Vibrio parahaemolyticus from surrounding water to Litopenaeus vannamei. Food Microbiol 2025; 129:104757. [PMID: 40086986 DOI: 10.1016/j.fm.2025.104757] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2024] [Revised: 02/01/2025] [Accepted: 02/17/2025] [Indexed: 03/16/2025]
Abstract
Microplastics (MPs) pose a major threat to marine life and ecosystems. However, the toxicological effects of MPs on crustaceans which are highly susceptible to MPs pollution are not fully understood. In addition, MPs can serve as the medium for pathogens, increasing the risk of disease outbreaks in shrimp aquaculture. To study the biological risks of MPs close to the aquacultural practice, the current study firstly focused on the impacts of MPs colonized by the pathogen Vibrio parahaemolyticus on shrimp Litopenaeus vannamei. The role of microplastics in facilitating pathogens infection of shrimps was firstly reported. Under this impact, the hepatopancreas of L. vannamei suffered severe damage. At 96 hpi, the shrimp mortality rate reached 100%. Dominant phyla altered in the intestinal and hepatopancreatic microbiota of L. vannamei. The characterization of the L. vannamei microbiota under the condition where the pathogens and MPs exist in the surroundings, to be used as a reference for comparison with healthy and diseased shrimp in the aquacultural system, is necessary.

Nanoplastic exposure weakens immunocompetence in the burrowing tarantula (Chilobrachys guangxiensis) following pathogen-associated molecular pattern challenges. ENVIRONMENTAL RESEARCH 2025; 274:121332. [PMID: 40058554 DOI: 10.1016/j.envres.2025.121332] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/20/2025] [Revised: 02/27/2025] [Accepted: 03/06/2025] [Indexed: 03/16/2025]
Abstract
Nanoplastics (NPs) have emerged as critical environmental contaminants, with growing concerns regarding their potential harm to organisms. Despite this, knowledge remains limited on whether NP exposure diminishes the capacity of organisms to respond to additional environmental stressors. In this study, we evaluated immune function in a burrowing tarantula, Chilobrachys guangxiensis, following NP exposure and subsequent challenges with lipopolysaccharide (LPS) and β-1,3-glucan. The total hemocyte count (THC) and hemolymph encapsulation rate were assessed to determine immune disruption. In addition, transcriptomic analyses were conducted to elucidate the mechanisms involved after both primary and secondary exposures. Results indicated that prolonged NP exposure did not cause significant changes in immunocompetence in C. guangxiensis. However, upon secondary exposure to LPS or β-1,3-glucan, individuals pre-exposed to NPs displayed significant changes in THC and impaired encapsulation capacity. Gene expression profiling based on quantitative real-time PCR revealed that LPS and β-1,3-glucan elicited varying immune responses and distinct gene expression profiles in NP-exposed C. guangxiensis. These findings suggest that NP exposure weakens immunocompetence in C. guangxiensis. This study provides comprehensive insights into the immune responses triggered by different pathogen-associated molecular patterns in NP-exposed C. guangxiensis, offering a novel perspective on the complex immunotoxicological effects of NP pollution.

Impact of microplastics exposure on the reconfiguration of viral community structure and disruption of ecological functions in the digestive gland of Mytilus coruscus. JOURNAL OF HAZARDOUS MATERIALS 2025; 494:138692. [PMID: 40403370 DOI: 10.1016/j.jhazmat.2025.138692] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/08/2025] [Revised: 05/19/2025] [Accepted: 05/19/2025] [Indexed: 05/24/2025]
Abstract
Microplastics (MPs) pose ecological risks by serving as viral vectors and disrupting host microbiomes. This study investigated the impact of MPs on the digestive gland virome of Mytilus coruscus through an in situ exposure experiment on Xixuan Island, Zhoushan, China, using polyethylene MPs and metagenomic sequencing. MPs biofilms were dominated by lytic viruses (> 99 %) with low diversity (Shannon index = 4.10 ± 0.39), whereas digestive glands harbored a more diverse virome (Shannon index = 7.26 ± 1.26). MPs ingestion significantly reduced virome diversity and altered viral community composition. Functional analysis showed that MPs biofilms were enriched in genes related to genetic processing, carbohydrate metabolism and membrane biogenesis, while transcription- and replication-related genes declined (P < 0.05) in digestive glands post-ingestion. MPs biofilms carried abundant antibiotic resistance genes (ARGs) and virulence factors, selectively enriching multidrug resistance genes (efrA, patB) while reducing functional viral gene abundance. Metal (Zn, Hg, As) and biocide resistance genes were prevalent in MPs biofilms but declined post-ingestion. Additionally, MPs ingestion weakened microbial network stability, potentially impairing immune regulation and metabolic homeostasis. These findings underscore MPs' role in shaping viral communities and spreading resistance genes, heightening ecological risks in marine environments.

Abstract
Polystyrene microplastics (PS-MPs) pose significant risks to honeybee health. However, how microplastics (MPs) adversely influence honeybee survival through the gut pathway, especially the metabolic processes, remains poorly understood. To conduct the experiment, the honeybees (Apis mellifera L.) were exposed to PS-MPs (0.5 μm and 5 μm) at environmental concentrations of 25 mg/L and 50 mg/L for 21 days. Results revealed that PS-MPs reduced honeybee survival rates and food consumption. The accumulation of PS-MPs in honeybee guts caused structural damage to gut walls and elevated oxidative stress levels. Additionally, PS-MPs altered gut microbial communities, with a decrease in Lactobacillus and an increase in Bartonella. Gut metabolomics analysis indicated that PS-MPs disrupted metabolic pathways, upregulated amino acid and carbohydrate metabolism, and downregulated alpha-linolenic acid and lipid metabolism. Our study offers important insights into the physiological effects of accumulated MPs on honeybees, highlighting the critical need for effective strategies to manage environmental pollutants.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 955:177010.

Abstract
Research on microplastics and plastispheres now incorporates the study of viruses to evaluate their effects on the environment and human health. Sharing these new discoveries with the scientific community is crucial to fostering further research and collaborations. However, the current research and methodologies used are fragmented. To address this issue, this paper reviews the literature and the use of methodology developments in each study, identifying four emerging research areas: (1) viral interactions with microplastics; (2) viral population, diversity, and function in plastispheres; (3) the effects of viruses and plastic particles in host-associated environments; and (4) the impacts of viruses within plastispheres. To that end, the article is structured to streamline navigation and help readers easily access existing approaches, recent advancements, key findings, challenges, and opportunities in these areas. Our synthesis reveals that research methods include biochemical assays, omics techniques, spectroscopic analysis, and molecular and bioinformatic tools. Various mechanisms enable viruses to attach to microplastics and plastispheres, leading to widespread distribution and contributing to toxic effects and gene transfer. While the growing evidence is intriguing, there is still much to uncover about their ecological interactions, functions, and impacts.

A critical review of microplastics in the shrimp farming environment: Incidence, characteristics, effects, and a first mass balance model. THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 955:176976.

Abstract
This review provides a critical overview of the sources, incidence, accumulation, effects, and interactions of microplastics (MPs) with other contaminants in the shrimp aquaculture environment, emphasizing this sector's challenges and future implications. A first and novel mass MPs balance model was developed to explore the fate and fluxes of MPs within shrimp farming systems. Two literature searches were conducted: one focused on MPs, crustaceans, and shrimp in aquaculture, and other on the effects of MPs in crustaceans, emphasizing shrimp. A total of 78 and 461 peer-reviewed papers were retrieved, respectively. This review details aspects of MPs in the shrimp farming environment, including water, sediments, food, zooplankton, and shrimp tissues. MPs can act as vectors for contaminants, including biological and chemical substances commonly used in shrimp aquaculture. A primary concern is the interaction between MPs and pathogens; thus MPs can facilitate the transport and retention of disease-causing agents. Key questions involve identifying which pathogen groups are most efficiently transported by MPs and how this may exacerbate disease outbreaks in aquaculture. This suggests that microorganisms can establish on MPs surfaces to disseminate an infection. Therefore, the possibility of disease outbreaks and epidemics is expected to rise as MP abundance increases. The mass balance shows that the primary source of MPs is associated with water during the filled (19.3 %) and water exchange (77.2 %) of shrimp ponds, indicating that MPs in the water input play a critical role in the MP dynamic in the shrimp farming environment. However, this initial mass balance model has several weaknesses, including liming, atmospheric deposition, and natural food, which must be addressed as other MPs suppliers. Macrofauna that incidentally enters shrimp ponds may also constitute a significant part of the MPs inventory. Future research should focus on the impact of polystyrene and polyethylene fibers commonly found in crustacean tissues.

FISH & SHELLFISH IMMUNOLOGY 2024; 154:109977.

Abstract
The white spot syndrome virus (WSSV) causes white spot disease (WSD), a severe condition in crustacean aquaculture, leading to significant economic losses. Our previous study demonstrated that C7 is an effective therapeutic agent against WSSV infection in aquaculture. It specifically blocked viral horizontal transmission and reduced shrimp mortality in a dose- and time-dependent manner. Here, we report the potential antiviral mechanism of C7 in shrimp. C7 regulated abnormal glycerophospholipid metabolism caused by WSSV and inhibited phosphatidylcholine (PC) synthesis by more than twofold, potentially enhancing shrimp resistance to viral infection. As the primary phospholipid in the cell membrane, PC is one of the main reactants in lipid peroxidation. Our results indicated that C7 significantly reduced the levels of lipid peroxidation products 4-hydroxynonenal (4-HNE) and malondialdehyde (MDA) induced by WSSV, whereas PC had the opposite effect. Accumulation of lipid peroxidation products inhibits stimulator of interferon genes (STING) signaling. Further evidence showed that C7 promoted STING transport from the endoplasmic reticulum to the Golgi apparatus, significantly activating the expression of the shrimp interferon analogue Vago4 gene. In contrast, PC suppressed Vago4 expression. Our results demonstrated that C7 inhibited PC synthesis, reduced the degree of lipid peroxidation, promoted STING translocation, activated Vago4 expression, and ultimately exerted antiviral effects. Therefore, C7 exhibits immunoregulatory activity as a preventative agent for enhancing the innate immunity of shrimp, making it potentially useful for future immunomodulatory approaches.

Abstract
Novel pollutants nanoplastics (NPs) are widely distributed in aquatic environments and may pose a health threat to aquatic organisms. Notably, the contribution of NPs to the occurrence of viral diseases in aquatic animals remains largely uncertain. In this study, the effects of polystyrene nanoplastics (PS-NPs) on Largemouth bass ranavirus (LMBV)-infected MsF cells were investigated. MsF cells took up PS-NPs in a time- and dose-dependent manner and significantly affect cell viability at an exposure concentration of 500 μg/mL. Western blot and qPCR assays indicated that exposure to PS-NPs accelerated LMBV replication in MsF cells. PS-NPs act synergistically with LMBV to disrupt the cellular antioxidant system, as evidenced by increased ROS production and decreased mRNA levels of antioxidant-associated genes. Furthermore, PS-NPs was found to exacerbate LMBV-induced inflammatory responses, as demonstrated by disturbed expression of inflammation-related factors. In addition, our results suggest that PS-NPs reduce IFN production by inhibiting the expression of molecules related to the cGAS-STING signaling pathway, thereby promoting viral replication. Collectively, our findings suggest the potential threat of NPs to infectious diseases caused by freshwater fish viruses and provide new insights for fish disease prevention and control.

Abstract
Plastic waste has emerged as a major environmental concern in recent years. As plastic waste discharged into the marine environment, it undergoes a breakdown process, eventually accumulating in aquatic organisms in the form of microplastics (MPs). To date, reduced food intake, nutritional absorption, and impaired immune system are known adverse effects of MPs-exposed aquatic organisms. This study aims to investigate whether MP exposure accelerated white spot syndrome virus (WSSV) infection in Pacific white shrimp (Penaeus vannamei) via laboratory tests. Briefly, experimental shrimp were divided into four groups; WSSV (group 1); MP (group 2); WSSV + MP (group 3); and Control (group 4). No mortality was observed in group 2, group 4, and even in group 1. However, group 3 showed a cumulative mortality of 50% during the experimental period. The PCR assay results showed no WSSV in the other three groups (groups 1, 2, and 4), but the dead and alive shrimp collected from group 3 were confirmed to be infected with the virus. Histopathological examination revealed normal structures in the hepatopancreas, gill, and muscle tissues of group 4, whereas numerous abnormally shaped nuclei were detected in the gill tissue of group 2. Moreover, group 1 showed minor WSSV-related lesions with few basophilic inclusion bodies in the gills, interestingly, group 3 exhibited severe lesions with numerous basophilic inclusion bodies in the gills. In conclusion, this study confirmed the correlation between the viral disease of shrimp and MPs, which can cause significant economic losses to the shrimp aquaculture industry.

Fluxapyroxad (FX), a typical succinate dehydrogenase inhibitor fungicide, is causing increased global concerns due to its fungicide effects. However, the accumulation and grow toxicity of FX to Litopenaeus vannamei (L. vannamei) is poorly understand. Therefore, the accumulation pattern of FX in L. vannamei was investigated for the first time in environmental concentrations. FX accumulated rapidly in shrimp muscle. Meanwhile, growth inhibition was observed and the mechanism derived by primarily accelerated glycolipid metabolism and reduced glycolipid content. Moreover, exposure to environmental concentrations of FX induced significant growth inhibition and oxidative stress and inhibited oxidative phosphorylation and TCA cycle in L. vannamei. The endocytosis signaling pathway genes were activated, thereby driving growth toxicity. Oxidative phosphorylation and cytosolic gene expression were further rescued in elimination experiments, demonstrating the mechanism of growth toxicity by FX exposure. The results revealed that FX persistently altered the gut microbiome of L. vannamei using gut microbiome sequencing, particularly with increased Garcinia Purple Pseudoalteromonas luteoviolacea for organic pollutant degradation. This study provided new insights into the potential toxicity of FX to marine organisms, emphasizing the need for further investigation and potential regulatory considerations.

Abstract
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.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 930:172679. [PMID: 38677436 DOI: 10.1016/j.scitotenv.2024.172679] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/10/2024] [Revised: 03/30/2024] [Accepted: 04/20/2024] [Indexed: 04/29/2024]
Abstract
Procypris merus, a local fish species found in Guangxi, China is often exposed to both microplastics (MPs) and Cd. However, it remains unclear how these two pollutants affect P. merus. Therefore, we investigated the effects of MPs on Cd accumulation in P. merus. To this end, P. merus was separately exposed to Cd and MPs (500 μg/L) or their combination for 14 days. We found that MPs enhanced Cd accumulation in liver and gills of P. merus. Further, both the single-contaminant (MP and Cd) and combined treatments resulted in lesions in these two tissues, with more severe damage associated with the combined treatment. Even though the effect of MP on the antioxidant defense system of P. merus was limited, the Cd-only and combined treatments considerably affected the antioxidant parameters of P. merus, with the combined treatment showing a stronger effect. GO and KEGG analyses revealed that the differentially expressed genes (DEGs; TNF-related apoptosis-inducing ligand receptor, trail-r) in the Cd-only treatment group were enriched for immune-related GO terms and cell growth and death related pathways, indicating that Cd toxicity affected immune defense in P. merus. The MP-only treatment downregulated DEGs (acyl-CoA synthetase long chain family member 1a, acsl1a) related to lipid metabolism, possibly leading to lipid accumulation in the liver. The combined treatment also upregulated DEGs (aspartate aminotransferase 1, ast 1) associated with immune-related GO terms and amino acid metabolism pathways, suggesting that it affected immune function in P. merus, thereby negatively impacting its health. Results indicated that MPs have additive effects on Cd accumulation and toxicity in rice flower carp. Consequently, MPs ingested by P. merus can promote Cd accumulation, more adverse effects on the health may occur after combined exposure, which can eventually reach humans through the food chain and pose potential risks to human health.

Toxic effects of microplastics and nitrite exposure on intestinal histology, digestion, immunity, and microbial community of shrimp Litopenaeus vannamei. MARINE POLLUTION BULLETIN 2024; 200:116077. [PMID: 38330811 DOI: 10.1016/j.marpolbul.2024.116077] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/04/2023] [Revised: 01/22/2024] [Accepted: 01/24/2024] [Indexed: 02/10/2024]
Abstract
Nitrite and microplastics (MPs) are environmental pollutants that threaten intestinal integrity and affect immune function of shrimp. In this study, the shrimp Litopenaeus vannamei were exposed to the individual and combined stress of nitrite and microplastics for 14 days, and the changes of intestinal histology and physiological functions were investigated. After single and combined stress, affectations occurred in intestinal tissue; the antioxidant enzyme activities (MDA, H2O2, CAT increased) and gene expression levels (CAT, SOD, GPx, HSP70 up-regulated) changed. The expression levels of detoxification genes (CYP450, UGT down-regulated, GST up-regulated), apoptosis genes (CASP-3 up-regulated) and endoplasmic reticulum stress genes (Bip, GRP94 down-regulated) changed. Furthermore, the stress also increased intestinal microbial diversity, causing bacterial composition variation, especially beneficial bacteria and pathogenic bacteria. These results suggested that nitrite and microplastics stress had adverse effects on the intestinal health of L. vannamei by affecting intestinal tissue morphology, immune response and microbial community.

ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2024; 342:123054. [PMID: 38043770 DOI: 10.1016/j.envpol.2023.123054] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/06/2023] [Revised: 11/17/2023] [Accepted: 11/25/2023] [Indexed: 12/05/2023]
Abstract
Microplastics (MPs) pollution is a hot issue of global concern. Polypropylene microplastics (PP-MPs) age quickly in the marine environment and break down into smaller particles because of their relatively low temperature resistance, poor ultraviolet resistance, and poor antioxidant capacity, making them one of the major pollutants in the ocean. We assessed whether long-term exposure to micron-sized PP-MPs influences fish susceptibility to viral diseases. We found that exposure to PP-MPs (1-6 μm and 10-30 μm) at concentrations of 500 and 5000 μg/L resulted in uptake into spleen and kidney tissues of Lateolabrax maculatus. Increased activation of melanomacrophage centers was visible in histopathological sections of spleen from fish exposed to PP-MPs, and greater deterioration was observed in the spleen of fish infected by largemouth bass ulcerative syndrome virus after PP-MPs exposure. Additionally, exposure to PP-MPs led to significant cytotoxicity and a negative impact on the antiviral ability of cells. PP-MPs exposure had inhibitory or toxic effects on the immune system in spotted sea bass, which accelerated virus replication in vivo and decreased the expression of the innate immune- and acquired immune related genes in spleen and kidney tissues, thus increasing fish susceptibility to viral diseases. These results indicate that the long-term presence of micron-sized PP-MPs might impact fish resistance to disease, thereby posing a far-reaching problem for marine organisms.
