We characterized the occurrences of typical disinfectants and microeukaryotic communities in surface waters associated with three wastewater treatment plants (WWTP)-river systems one year after the lockdown in Wuhan, China. Trihalomethanes (THMs) declined from summer 2020 (0.01–1.82 ​μg/L) to summer 2021 (0.01–0.95 ​μg/L), whereas quaternary ammonium salts (QAs) increased from summer 2020 (0.53–6.35 ​ng/L) to summer 2021 (8.49–191 ​ng/L). Biodiversity monitoring with environmental DNA (eDNA) revealed significant temporal variation in microeukaryotic community composition. The monitored disinfectants were correlated with some eukaryotic communities as demonstrated by redundancy analysis. For example, QAs were positively related to Cryptophyta relative abundance, but negatively related to Rotifera relative abundance. A microeukaryote-based multimetric index indicated ecological impairment near the Han River WWTP outlet in 2020. Our findings indicate the influence of heavily used disinfectants on river microeukaryotic communities, and the usefulness of assessing mid-term ecological risks from disinfectants in the post COVID-19 era.</p></div>","PeriodicalId":101277,"journal":{"name":"Water Biology and Security","volume":"3 3","pages":"Article 100266"},"PeriodicalIF":5.1,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772735124000222/pdfft?md5=63bdc043a6d4cc836bb79b061bc7cd04&pid=1-s2.0-S2772735124000222-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140796949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Within the SOCS family, SOCS3 is one of the most potent inhibitors of cytokine signaling. However, there is limited knowledge regarding the function of SOCS3 on regulating type I interferon (IFN) signaling in fish. In this study, the complete open reading frame (ORF) of <em>SOCS3</em> from the large yellow croaker (<em>Larimichthys crocea</em>, <em>LcSOCS3</em>) was cloned and characterized. The ORF of <em>LcSOCS3</em> was 618 nucleotides in length and encoded a protein containing 205 amino acids. <em>Lc</em>SOCS3 had the typical domain architecture of the SOCS family, including an SRC homology 2 (SH2) domain, a SOCS box, an additional kinase inhibition region (KIR), and an extended SH2 subdomain (ESS). Phylogenetic analysis revealed that <em>Lc</em>SOCS3 was clustered with other fish SOCS3s and most closely related to the SOCS3 of <em>Collichthy lucidus</em>. <em>LcSOCS3</em> mRNA was detected in all organs or tissues examined, and its expression was significantly increased in both head kidney and spleen tissues, and primary head kidney leukocytes after poly(I:C) stimulation. Overexpression of <em>Lc</em>SOCS3 significantly promoted Spring viremia of carp virus (SVCV) replication, resulting in a more severe cytopathic effect, increased viral titer, enhanced copy number of the SVCV-G gene, and decreased expression levels of <em>IFN1</em>, <em>IRF7</em>, <em>ISG15</em>, <em>Viperin</em>, <em>PKR</em>, and <em>Mx</em> in epithelioma papulosum cyprinid (EPC) cells. Silencing of <em>LcSOCS3</em> correspondingly up-regulated the expression of <em>IFNi</em>, <em>IFNh</em>, <em>PKR</em>, <em>Viperin</em>, and <em>Mx</em> in large yellow croaker head kidney (LYCK) cells. Additionally, <em>Lc</em>SOCS3 was shown to interact with Signal Transducer and Activator of Transcription 1 (STAT1) which may inhibit STAT1 translocating into the nucleus. This speculation was supported by the increased phosphorylation level of STAT1 in head kidney leukocytes after <em>Lc</em>SOCS3 silencing.

As the most ancient vertebrates, teleost fish continuously secrete a substantial amount of mucus due to their unique living environment, and often exhibit schooling behavior. Previous studies have highlighted the presence of numerous immune components in the mucus of fish, that plays a crucial role in resisting pathogens. We hypothesize that this represents a distinctive maternal immune response mechanism in fish. In this study, we established a dextran sulfate sodium (DSS)-induced injury model by immersing zebrafish larvae in 0.5% DSS. This elicited robust inflammatory responses and showed DSS-induced alterations in microbial abundance via 16S rRNA sequencing. These changes included the disruption of normal gut structure; an increase in goblet cells; increased expression of inflammatory cytokines; and infiltration of neutrophils and macrophages into the gut, as well as an increase in pathogenic bacteria and a decline in probiotic bacteria. Furthermore, we conducted a mucus protection test by adding adult zebrafish mucus in fish tank water containing 0.5% DSS to test our hypothesis. As suspected, the mucus from adult zebrafish exhibited a protective role in defending zebrafish larvae against DSS-induced enteritis by alleviating excessive inflammatory responses and increasing probiotic abundance. In conclusion, our results confirm a significant role of adult fish mucus in the immune response of teleost fish to DSS-induced inflammation. Collectively, our findings show that the mucus of adult zebrafish may represent a novel form of maternal immunization, playing roles analogous to mammalian milk in immune regulatory functions.</p></div>","PeriodicalId":101277,"journal":{"name":"Water Biology and Security","volume":"3 2","pages":"Article 100248"},"PeriodicalIF":0.0,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772735124000040/pdfft?md5=c96851a9e247a61e9dfc1b3f75bc13cc&pid=1-s2.0-S2772735124000040-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139885824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite inherent biases against these species, a better understanding of their characteristics allows for the identification of those of greatest concern, minimizing the risk of food shortages and infectious diseases. This review summarises the positive and negative impacts of non-native species, delineating the specific areas they may impact. Additionally, this review gives an insight to the expertise and stakeholders that would need to be included if a “One-Health” approach were to be implemented by policymakers to better control non-native species.</p><p>Detailed examples illustrate the consequences of non-native species on trophic dynamics, ecosystem health, water chemistry, and human health, emphasizing the importance of managing them within a multidimensional framework. The “One-Health” approach is explained, and suggestions are made on how certain non-native species could be used to contribute to food security in low- and middle-income countries. Furthermore, recommendations are made to promote a more inclusive management strategy.</p></div>","PeriodicalId":101277,"journal":{"name":"Water Biology and Security","volume":"3 2","pages":"Article 100250"},"PeriodicalIF":0.0,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772735124000064/pdfft?md5=83ac24b011449d9e4b758aa2fb59e0dc&pid=1-s2.0-S2772735124000064-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140271559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
