Systems-based research examining how food production impacts on AMR in complex agrifood systems is lacking, with little written on management approaches in the UK that might prevent and respond to this challenge. One approach is the creation of a transdisciplinary network to enhance capacity, capability and collaboration between agrifood-focused disciplines and stakeholders. This co-creation platform for network-wide systems-based activities would reduce inefficiencies in AMR-related activities around agrifood, providing a cross-cutting, cohesive community to deliver transformational guidance on relevant, practical agrifood solutions that add value by reducing AMR, antimicrobial usage and associated costs, and decreasing resultant environmental contamination by prioritising challenges, sharing knowledge and best practice, and co-creating practical solutions with key stakeholders. An online survey determined prospective network focus, structure and priorities, with responses analysed using mixed methods.</p><p>Survey results suggested respondents have interests in synthesising data using systems-approaches and using certain disciplines such as ‘social sciences’ within network activities. There were disconnects in how and whom to work with on this, with generalised use of ‘social science/scientists’ but lack of disciplinary understanding (e.g., anthropology, sociology) suggesting disciplinary differences awareness-training is useful. A similar generalisation is seen for mathematics/statistics. There are strong interests in working with food system practitioners (e.g., farmers/vets), providing opportunities for farm/field visits/knowledge exchange, and human health, reflecting the need for farm-to-fork understanding of impacts. There were notable mentions of policy/governance, emphasising translational research desires to create meaningful change. Disciplines/fields did not always align with identified interests e.g., systems and implementation science, suggesting the utility of network activity around introducing these disciplines e.g., methodology-focused rather than subject-focused conferences exploring lateral thinking about subjects.

Our previous research identified both viruses in effluent wastewater in Gothenburg, Sweden. However, there are lingering inquiries regarding the prevalence and genetic diversity of these viruses in influent wastewater, as well as the utility of wastewater surveillance in elucidating their community circulation dynamics. To address these knowledge gaps, we conducted weekly collection of wastewater samples at the Rya wastewater treatment plant in Gothenburg throughout 2023. The concentrations of HEV and RHEV were quantified using quantitative polymerase chain reaction (qPCR). Additionally, two semi/nested-PCR were utilized to amplify viral strains. Furthermore, HEV strains from patients within the same region, as well as other regions in Sweden in 2023, were incorporated into the analysis. Remarkably, we observed a high prevalence of HEV (86%) and RHEV (98%) in wastewater samples, with the majority of HEV sequences identified as subtype 3c/i (9/12). In contrast, HEV subtype 3f was the most sequenced among clinical patient samples (6/12). Notably, previously unreported HEV-3b and unclassified strains were detected in wastewater. Almost all RHEV strains (20/21) were clustered into European groups, with none of the RHEV genetically close to strains previously found in human cases. The notable discordance in prevalence and identified subtypes of HEV-3 in wastewater compared to clinical samples suggests either a significant underdiagnosis of HEV infections or differences in viral loads and shedding durations among humans between HEV-3 subtypes. This underscores the urgent need for improved diagnostic techniques and heightened awareness of HEV transmission dynamics. Furthermore, the consistent detection of RHEV in wastewater underscores the necessity for further investigations to assess the potential role of RHEV in hepatitis cases of unknown etiology, given that most currently available clinical diagnostic assays fail to detect RHEV.</p></div>","PeriodicalId":19577,"journal":{"name":"One Health","volume":null,"pages":null},"PeriodicalIF":4.1,"publicationDate":"2024-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2352771424002088/pdfft?md5=55e9b7deb8be4c10ec0f0f9d81d03f05&pid=1-s2.0-S2352771424002088-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142049731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluated WBS as a pandemic preparedness tool, by selectively isolating and culturing methicillin-resistant <em>Staphylococcus aureus</em> (MRSA) with CHROMagar MRSA. Some 24-h composite wastewater samples (<em>n</em> = 80) were collected from ten treatment plants across Finland between February 2021 and January 2022. MRSA prevalence in wastewater samples was 27.5% (<em>n</em> = 22/80), showing seasonal and temporal variations. Phenotypic antimicrobial susceptibility testing (AST) with microdilution showed that over 80% of isolates were drug-resistant to clindamycin, sulfamethoxazole/trimethoprim, tetracycline, fusidic acid, and erythromycin. Four isolates (18.2%) were vancomycin-resistant. WGS revealed that 31.8% (<em>n</em> = 7) of the isolates belonged to the ST8-<em>t</em>008 and ST6-<em>t</em>304 <em>spa</em> types, respectively. In addition, two <em>spa</em> types (<em>t</em>011 and <em>t</em>034) belong to the CC398 complex. The <em>mec</em>A gene was found in all isolates (<em>n</em> = 22) and three tetracycline resistance determinants (<em>tet</em>38, <em>tet</em>K, and <em>tet</em>M) were detected with <em>tet</em>38 being the most abundant (81.8%, <em>n</em> = 18/22). Three isolates harboured the plasmid-mediated <em>sat</em>4 gene that confers resistance to Streptothricin. In addition, resistance determinants to macrolide antibiotics (<em>mph</em> (C)/<em>msr</em> (A) and fosfomycin (<em>fos</em>B) were detected in the seven isolates that belonged to <em>spa</em> type <em>t</em>008. All isolates except one harboured the SCC<em>mec_</em>type_IVa(2B). Six ST8 isolates harboured the LukS/F-PV genes encoding the Panton–Valentine leukocidin (PVL) and were also positive for the Arginine Catabolic Mobile Element (ACME), suggesting they belong to the USA300 clone. The Inc18 plasmid was the most abundant as it was detected in 72.7% (<em>n</em> = 16/22) of the isolates. Other plasmid replicons detected were the rep_trans and repA_N which were detected in 45.4% (<em>n</em> = 10/22) and 40.9% (<em>n</em> = 9/22) of the isolates respectively. Ten isolates harboured at least three plasmid replicons and no plasmid replicons were detected in four isolates (ST6/<em>t</em>304). The cgMLST revealed that some isolates aggregated into two genomically indistinguishable clusters: ST6/<em>t</em>304 belonging to cluster type CT12405 (≤20 allelic differences) and ST8/<em>t</em>008 belonging to cluster type CT1925 (&lt;8 allelic differences). Overall, we found a high genotypic concordance with the national clinical bacterial resistance data.

Through this study, we hope to contribute to eradication of rabies in Morocco by providing reliable data and practical recommendations for control actions against rabies.</p></div>","PeriodicalId":19577,"journal":{"name":"One Health","volume":null,"pages":null},"PeriodicalIF":4.1,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2352771424002003/pdfft?md5=4eb6a946782eb1f661378c227071215f&pid=1-s2.0-S2352771424002003-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141992671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
