A conservation translocation (reintroduction) programme has contributed to recovery by establishing new populations and regaining the lost range of the species. The translocation of wild animals has been associated with severe epidemic disease giving rise to extinctions, and therefore, caution is required in the planning of future translocations. In line with International Union for the Conservation of Nature recommendations, a disease risk analysis was conducted on the sand lizard reintroduction programme in 2003. A disease outbreak, associated with the bacterium Serratia marcescens, occurred in a sand lizard colony being prepared for reintroduction in 2004, and S. marcescens had not previously been recorded in reptiles in England. In order to reassess disease risk management methods, efforts were made to establish whether this bacterium was a naturally occurring species in UK sand lizards, and a survey was conducted on 194 free-living, wild sand lizards from a population that had not received reintroduced sand lizards. Cloacal swabs, collected from the free-living sand lizards, were cultured for bacteria, and S. marcescens was recorded at 1.5% prevalence (n = 194). Given this finding, the risk from disease, associated with S. marcescens, in the reintroduction of sand lizards from the captive colony was considered low, and conservation translocation continued. The practical, feasible disease risk management methods, described in this paper, can be utilised to reduce the risks from disease of conservation translocations and safeguard future populations.","PeriodicalId":51027,"journal":{"name":"Ecohealth","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148654998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data from 384 respondents revealed that only 15% were aware of zoonotic diseases, despite 80% reporting frequent disease outbreaks. Access to health care was limited for 71% of participants, hindered by geographic isolation, poor transportation, and financial constraints. A significant positive correlation (r = 0.641, p < 0.05) was found between knowledge, attitudes, and practices, suggesting that greater awareness can lead to improved health behaviors. Traditional healing systems, including herbal and spiritual remedies, were used by 75% of respondents. However, poor hygiene and livestock care practices, such as infrequent handwashing (60%) and low vaccination rates (90%), further increased health vulnerabilities. The findings urge the adoption of integrated, culturally responsive healthcare methods based on the One Health concept. Mobile health and veterinary units, community-driven health education, and participatory disease surveillance should all be implemented to successfully minimize zoonotic hazards and enhance the overall well-being of transhumant communities.","PeriodicalId":51027,"journal":{"name":"Ecohealth","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148632653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there is a knowledge gap that has not yet been addressed by these shortfalls, representing one of the most important components of biodiversity with implications for human well-being and species conservation: the zoonoses. Here, we introduce the concept of the Chagasian shortfall, which refers to our insufficient knowledge of pathogens, reservoirs and/or hosts, vectors, and, most importantly, epidemiological cycles, making it difficult to understand how zoonotic diseases spread across different dimensions.

This study explores how combining epidemiological data with indigenous traditional knowledge, derived from community surveys, can improve the understanding and management of ciguatera on Ambae Island in Vanuatu. A mixed-methods approach was employed, integrating a review of health facility records with community survey data. Data were collected from seven health facilities serving the three area councils (East, North, and West) of Ambae Island based on the period from 2015 to 2024. The results show that CFP cases peaked in April, May, October, and November, with the highest annual case numbers recorded in 2017 and 2024. Nduindui and Walaha Health Centres reported the highest number of cases, followed by Lolopuepue Health Centre. According to area councils, West Ambae recorded the highest incidence rates, approximately 937 cases per 100,000 people per month and 765 cases per 100,000 people per year, compared to lower rates in the North and East Area Councils. The community survey revealed that 85% of the 97 respondents experienced symptoms consistent with ciguatera. Additionally, 25 local plant species were identified as traditional treatments for CFP symptoms across the three area councils. Expanding comparative surveillance across other islands in Vanuatu and the Pacific could strengthen CFP management and public health responses.","PeriodicalId":51027,"journal":{"name":"Ecohealth","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148622450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We discuss persistent barriers to the advance of disease ecology, such as disciplinary siloes, differing methodologies, and lack of incentives that continue to hinder collaboration despite increasing awareness of the importance of disease ecology research.

Key findings highlight the ability of local governments to rally stakeholders and form a progressive evidence-based response. While civil society's role is often overlooked, with appropriate government facilitation, it can serve as an effective agent of change on the ground. By adopting a bottom-up approach, this study provides a unique contribution to policy development discourse in line with One Health. The findings also emphasize challenges in the capacity of national and subnational governments to organize multi-actor responses, as well as the role of civil society and civic institutions in policy implementation. Persistent vulnerabilities at the human-wildlife interface were also evident, especially in relation to trade in wildlife, wild meat consumption, and the domestic keeping of wildlife, which have been exacerbated by fragmented coordination and implementation. New policy instruments, such as digital zoonotic disease surveillance, integrated early warning systems, and social forestry present opportunities for mitigating risk.

While the authors cogently argue for the integration of sustainability within diagnostic frameworks, there remains an urgent need to transition from qualitative advocacy to a more rigorous, quantitative paradigm of environmental accountability. This critique posits that the current reliance on voluntary \"eco-conscious\" shifts is insufficient against the backdrop of escalating global diagnostic demands. Specifically, the tension between the stringent requirements of clinical precision-governed by frameworks such as ISO 15189-and the mandates of ecological preservation requires a more nuanced exploration of \"regulatory synergy\". Of note, while the authors correctly identify the disparate impact on lower- and middle-income countries (LMICs), the discussion must move beyond infrastructural deficits to address the systemic \"exportation of ecological debt\" through the global medical supply chain. Furthermore, by implementing standardized Lifecycle Assessments (LCAs) and integrating sustainability metrics into the very core of healthcare accreditation, the laboratory sector can evolve from a passive participant in the Sustainable Development Goals (SDGs) to a proactive vanguard of the \"One Health\" initiative. This letter advocates for a mandatory \"Green Diagnostic Charter\" that transcends institutional goodwill to ensure that the pursuit of human health no longer occurs at the deleterious expense of our shared biosphere.","PeriodicalId":51027,"journal":{"name":"Ecohealth","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148594377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a resident wading bird species in western India, i.e., Udaipur city, Rajasthan. It inhabits a wide range of environments, including urban areas, wetlands, agricultural fields, and fallow lands. Fecal samples (n = 45) were collected and a total of 60 bacterial isolates were analyzed for bacterial diversity and bacteria were characterized using biochemical, molecular, methods. Interestingly, four novel bacterial taxa from this host species were identified, i.e., Enterobacter mori, Enterobacter soli, Citrobacter freundii, and Leclercia adecarboxylata. Notably, E. mori and E. soli were reported for the first time in this bird species globally. Antibiotic susceptibility testing revealed high levels of multidrug resistance, with 40% of isolates resistant to at least three classes of antibiotics. Notably, resistance to clinically important antimicrobials, including the third-generation cephalosporin cefotaxime and reduced susceptibility to the carbapenem imipenem, was observed, raising concerns for spread of antibiotic resistance bacteria. Resistance to linezolid (100%) and rifampicin (100%) was also observed across isolates, consistent with the intrinsic resistance of Gram-negative bacteria to these agents. Our findings reported the presence of antibiotic-resistant bacteria in wild bird species which may contribute to the spread of antibiotic resistance through their fecal deposits and pose a serious risk to the health of humans and wild animals.","PeriodicalId":51027,"journal":{"name":"Ecohealth","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148581128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite numerous studies on its prevalence across hosts and vectors, country-specific data remain unavailable. This systematic review and meta-analysis provide comprehensive insights into the prevalence of scrub typhus across humans, animal hosts, and vectors to aid disease control programs. The PECOS framework was used to identify eligible studies. A systematic search across six databases (PubMed, Scopus, Web of Science, Google Scholar, Krishikosh, and Shodhganga) was conducted in March 2024. Data were classified by diagnostics and disease distribution across hosts and vectors for narrative synthesis. Study bias was assessed using a prevalence study checklist. A random- or common-effects meta-analysis model estimated overall and subgroup pooled prevalence across population types and diagnostic tests, with heterogeneity measured by the I2 index. A total of 83 eligible studies published between 2003 and 2024 covered different regions, hosts, and vectors. The pooled prevalence (95% CI) of scrub typhus was 20% (11-34%) in 17,826 hospitalized AES cases, 19% (14-25%) in 28,617 hospitalized AUFI cases, and 13% (5-27%) in 14,828 community individuals. The animal level pooled prevalence in 1782 rodents/shrews was 6% (2-13%) with 6% (1-27%) of seroprevalence and 8% (3-19%) of molecular prevalence. The pooled prevalence in 1037 ectoparasite vector pools was 5% (1-17%). The meta-regression analysis suggested that geographical region, publication year, and sampling strategy were the prime moderators in community individuals, whereas season was the moderator in AUFI cases. Scrub typhus distribution was influenced by season, with regional differences in circulating strains as well as host and vector species predilection. This study highlights a high burden of disease in multiple hosts and vectors, along with hospitalized cases, suggesting differential diagnosis.
