Linkages between Soil Security and One Health: implications for the 2030 Sustainable Development Goals.

Soil provides multiple and diverse functions (e.g., the provision of food and the regulation of carbon), which underpin the health of animals, humans, the environment and the planet. However, the world's soils face existential challenges. To this end, the concept of Soil Security was developed, compelled to: "maintain and improve soils worldwide so that they can continue to provide food, fiber and fresh water, contribute to energy and climate sustainability and help to maintain biodiversity and the overall protection of ecosystem goods and services." In parallel, the concept of One Health likewise works across the human-animal-environment interface, highly relevant for the goals of Soil Security. In this review, we evaluated the roles which both the Soil Security and One Health concepts have served in the literature between 2012 and 2023 and explore the potential linkages between both concepts. We outline that both concepts are used in disparate fields, despite considerable overlap in aims and objectives. We highlight the Soil Health concept as a potential connector between Soil Security and One Health. Overall, we argue that both Soil Security and One Health are highly complementary fields of scientific inquiry with solid leverage for translation into policy and practice. However, there is a need to define One Health dimensions, as has been done for Soil Security. As such, we proffer five measurable dimensions for One Health, the "5Cs"-Capacity, Condition, Capital, Connectivity and Codification-to allow for an overall measure of One Health. Finally, we advocate for a biosphere-focused framework to collectively make progress toward the 2030 Sustainable Development Goals and other global existential challenges.

One Health collaboration is more effective than single-sector actions at mitigating SARS-CoV-2 in deer.

One Health aims to achieve optimal health outcomes for people, animals, plants, and shared environments. We describe a multisector effort to understand and mitigate SARS-CoV-2 transmission risk to humans via the spread among and between captive and wild white-tailed deer. We first framed a One Health problem with three governance sectors that manage captive deer, wild deer populations, and public health. The problem framing included identifying fundamental objectives, causal chains for transmission, and management actions. We then developed a dynamic model that linked deer herds and simulated SARS-CoV-2. Next, we evaluated management alternatives for their ability to reduce SARS-CoV-2 spread in white-tailed deer. We found that single-sector alternatives reduced transmission, but that the best-performing alternative required collaborative actions among wildlife management, agricultural management, and public health agencies. Here, we show quantitative support that One Health actions outperform single-sector responses, but may depend on coordination to track changes in this evolving system.

Applied One Health: Nigeria National Veterinary Research Institute COVID-19 pandemic response.

The COVID-19 pandemic has caused the death of 7.1 million people worldwide as of 7 July 2024. In Nigeria, the first confirmed case was reported on 27 February 2020, subsequently followed by a nationwide spread of SARS-CoV-2 with morbidity and mortality reaching 267 173 and 3155, respectively, as of 7 July 2024. At the beginning of the pandemic, only a few public health laboratories in Nigeria had the capacity for SARS-CoV-2 molecular diagnosis. The National Veterinary Research Institute (NVRI), already experienced in influenza diagnosis, responded to the public health challenge for the diagnosis of COVID-19 samples from humans. The feat was possible through the collective utilisation of NVRI human and material resources, including biosafety facilities, equipment, reagents and consumables donated by international partners and collaborators. Within 6 months of the reported COVID-19 outbreak in Nigeria, over 33 000 samples were processed in NVRI facilities covering five states. Thereafter, many field and laboratory projects were jointly implemented between NVRI and collaborating sectors including the Nigerian Centre for Disease Control (NCDC) and the National Institute for Medical Research (NIMR), which brought together professionals in the health, veterinary, education and socio-sciences. In addition, One Health grants were secured to enhance surveillance for coronavirus and other zoonoses and build capacity in genomics. Bio-surveillance for coronaviruses and other emerging zoonotic pathogens at the human-animal interface was activated and continued with sample collection and analysis in the laboratory for coronaviruses, Lassa fever virus and Mpox. One Health approach has shown that inter-sectoral and multinational collaboration for diagnosis, research and development in animals, and the environment to better understand pathogen spillover events at the human-animal interface is an important global health priority and pandemic preparedness.

Communication Breakdown - Of Disease Clusters, a Trillium and One Health.

One health is based on an interdisciplinary collaboration across professions using a common language. Geographic epidemiology is the study of spatial patterns of population health in a study area. Such spatial patterns (trend, cluster and clustering) require clear definition to be meaningful in science communication. However, the term "disease cluster" has been defined in the literature in various and rather different ways. When geographic epidemiology is unable to make sense of its own concepts it is questionable how respective research results can benefit one health. The goal of this study was to clarify the disease cluster concept. Examples of disease cluster definitions from the literature were used for illustration. The epidemiological triangle of causation (agent, host and environment) was used to conceptualize geographic epidemiological data analysis. The term disease cluster was distinguished from related concepts (clustering, high-risk area, hot spot and outbreak) additionally the semantics and statistical meaning of expectation and prediction were reviewed to further identify the cluster concept as a statistical outlier. The new paradigm of the geographic epidemiological trillium is proposed here and embedded within the spatial generalized linear mixed model to clarify concepts of spatial patterns and guide epidemiological research and teaching.

Modern agriculture and One Health.

BACKGROUND: The development of modern agriculture has significantly contributed to improving global food security and safety, alleviating poverty, and enhancing human health and livelihoods. However, the rapid advancement of modern agriculture has also brought about various challenges that limit its sustainable development. This commentary aims to discuss these issues through the One Health lens, and provide valuable insights for balancing modern agricultural activities with the need to protect and promote the health of all the sectors. MAIN TEXT: This commentary explores the multifaceted impacts of modern agriculture on social development, as well as the associated various health challenges and environmental impacts within the One Health framework. Key issues include ecosystem degradation, increased risk of interspecies disease transmission like zoonoses, reverse zoonoses, and vector-borne diseases, and the escalated threat of antimicrobial resistance due to intensified agricultural production and increased antimicrobial use. To address these challenges, this commentary outlines potential solutions anchored in the development and implementation of modern technologies and good agricultural practices, such as precision farming, integrated pest management, biosecurity measures, vaccination programs, as well as surveillance and early detection of health risks. CONCLUSIONS: Good agricultural practices supported by scientific and technological advancements are essential for aligning productivity with the One Health vision, ensuring the health and resilience of all the sectors. Enhancing stakeholder education, strengthening regulatory frameworks, and providing supportive policies and infrastructure for farmers to adopt sustainable practices are crucial for the long-term viability of agrifood systems. The Food and Agriculture Organization of the United Nations plays a pivotal role in guiding this sustainable transformation through the One Health approach.

Risk perceptions and preventive preparedness toward anthrax re-emergence within the lens of one health in Northcentral Nigeria.

Anthrax has re-emerged in domestic ruminants in Nigeria with public health concerns. This study assessed stakeholders' perceptions and preventive preparedness toward further resurgence and spread at the human-animal-environment interface. A questionnaire-based cross-sectional study was conducted in Nigeria. Descriptive and analytical statistical analyses were performed at 95% confidence levels. All the 384 recruited stakeholders responded. The majority (96.2%) of animal health practitioners (AHPs) and 56.7% of pastoralists were aware of the recent anthrax re-emergence in Nigeria (p < 0.001). Noteworthy, 88.5% of the AHPs and 32.2% of pastoralists mentioned that anthrax has an environmental component in its transmission to humans and animals. From the environmental perspective, 87.7% of AHPs and 24.0% of pastoralists significantly perceived that soil and aerosol contamination with anthrax spores are highly plausible explanation routes for its re-emergence. Extreme weather events (high rainfall, flooding, winds, and drought) (p = 0.001); grazing of livestock on pastures grown on contaminated soil (p < 0.001), transboundary movement and trade of animals (p = 0.001); introduction of new animals into the herds without quarantine (p = 0.001); and bioterrorism (p < 0.001) were more likely to influence the re-emergence and spread of anthrax. To tackle gaps in knowledge and risk perceptions, and address the socio-economic and anthropogenic drivers, cooperation and collaborations through the lens of the One Health approach are needed. The partnership will promote an integrated disease surveillance system from planning to implementation for the realization of elimination or reduction of the burden of anthrax and other zoonoses in Nigeria and contribute to achieving food safety, food security, and public and ecosystem health.

A One Health Approach to Public Safety: A Review of Police Canines in the United States.

Working dogs are an essential part of modern society, and police canines (K9s) in the United States are amongst the most recognizable of all working dogs. Given the dearth of published data on active police canines in the U.S. and the calls for police reform, an interdisciplinary effort is necessary to comprehensively understand how these dogs are best used for the benefit of society. This review paper relies on veterinary public health expertise to present a comprehensive overview of police canine use by municipal law enforcement in the United States, including known impacts and gaps in knowledge. The existing literature from animal-assisted interventions (AAI) provides evidence to ensure working dog well-being, while human-animal bond research contributes to officer safety and canine partnership. Lastly, law enforcement and public health agendas (LEPH) assure the team's successful efforts in built environments and local neighborhoods. These frameworks acknowledge the complexity of police dog use, spanning from punitive to public relations, which mirrors the role of law enforcement in U.S. society. This paper proposes the use of a One Health framework to ensure police canine contributions to society, including suggested approaches to partner municipal police with veterinary medicine and public health, and integrate One Health in promoting public safety for local communities.

Immunomics in one health: understanding the human, animal, and environmental aspects of COVID-19.

The coronavirus disease 2019 (COVID-19) pandemic underscores the critical need to integrate immunomics within the One Health framework to effectively address zoonotic diseases across humans, animals, and environments. Employing advanced high-throughput technologies, this interdisciplinary approach reveals the complex immunological interactions among these systems, enhancing our understanding of immune responses and yielding vital insights into the mechanisms that influence viral spread and host susceptibility. Significant advancements in immunomics have accelerated vaccine development, improved viral mutation tracking, and broadened our comprehension of immune pathways in zoonotic transmissions. This review highlights the role of animals, not merely as carriers or reservoirs, but as essential elements of ecological networks that profoundly influence viral epidemiology. Furthermore, we explore how environmental factors shape immune response patterns across species, influencing viral persistence and spillover risks. Moreover, case studies demonstrating the integration of immunogenomic data within the One Health framework for COVID-19 are discussed, outlining its implications for future research. However, linking humans, animals, and the environment through immunogenomics remains challenging, including the complex management of vast amounts of data and issues of scalability. Despite challenges, integrating immunomics data within the One Health framework significantly enhances our strategies and responses to zoonotic diseases and pandemic threats, marking a crucial direction for future public health breakthroughs.

The genetic relationship between human and pet isolates: a core genome multilocus sequence analysis of multidrug-resistant bacteria.

INTRODUCTION: The global increase of multidrug-resistant organisms (MDROs) is one of the most urgent public health threats affecting both humans and animals. The One Health concept emphasizes the interconnectedness of human, animal and environmental health and highlights the need for integrated approaches to combat antimicrobial resistance (AMR). Although the sharing of environments and antimicrobial agents between companion animals and humans poses a risk for MDRO transmission, companion animals have been studied to a lesser extent than livestock animals. This study therefore used core genome multilocus sequence typing (cgMLST) to investigate the genetic relationships and putative transmission of MDROs between humans and pets. METHODS: This descriptive integrated typing study included 252 human isolates, 53 dog isolates and 10 cat isolates collected from 2019 to 2022 at the Charité University Hospital in Berlin, Germany. CgMLST was performed to characterize methicillin-resistant Staphylococcus aureus, vancomycin-resistant enterococci and multidrug-resistant gram-negative bacteria. The genetic diversity of the MDROs of the different host populations was determined and compared based on sequence type and core genome complex type. RESULTS: Within this study the majority of samples from pets and humans was genetically distinct. However, for some isolates, the number of allelic differences identified by cgMLST was low. Two cases of putative household transmission or shared source of VR E. faecium and MDR E. coli between humans and pets were documented. CONCLUSIONS: The interaction between humans and their pets appears to play a minor role in the spread of the MDROs studied. However, further research is needed. This study emphasizes the importance of comprehensive molecular surveillance and a multidisciplinary One Health approach to understand and contain the spread of MDROs in human and animal populations. TRIAL REGISTRATION: The study is registered with the German Clinical Trials Register (DRKS00030009).

One Health: Urban birds peck up resistant pathogens.

A spatial-genomic analysis reveals that bird species living closer to humans have higher diversity of the pathogen Campylobacter and its antimicrobial resistance genes. This suggests that urbanization could promote pathogen transmission among wild animals and, potentially, humans.

Cancer and One Health: tumor-bearing individuals can act as super spreaders of symbionts in communities.

Recent theoretical advances in the One Health approach have suggested that cancer pathologies should be given greater consideration, as cancers often render their hosts more vulnerable to infectious agents, which could turn them into super spreaders within ecosystems. Although biologically plausible, this hypothesis has not yet been validated experimentally. Using a community of cnidarians of the Hydra genus (Hydra oligactis, Hydra viridissima, Hydra vulgaris) and a commensal ciliate species (Kerona pediculus) that colonizes them, we tested whether tumoral polyps of H. oligactis, compared to healthy ones, played an amplifying role in the number of ciliates, potentially resulting in a higher likelihood of infection for other community members through spillovers. Our results indicate that K. pediculus has a higher proliferation rate on tumoral polyps of H. oligactis than on healthy ones, which results in the infestation of other hydras. However, the magnitude of the spillover differed between recipient species. This study provides to our knowledge the first elements of proof of concept that tumoral individuals in communities could act as super spreaders of symbionts within and between species, and thus affect biotic interactions and dynamics in ecosystems.

Core-shell molecularly imprinted polymer sensor for enrofloxacin determination in various matrices: a novel, sustainable One Health analytical strategy.

Antibiotics are essential in treating infectious diseases in both humans and animals, and they are also utilized to enhance animal growth. However, their widespread use has led to significant environmental concerns. After administration of antibiotics, a substantial portion of them is excreted by animals, contaminating various environmental compartments. This problem is examined from the One Health perspective which seeks to balance human, animal, and environmental health for the benefit of global well-being. Enrofloxacin (ENR) is a commonly used antibiotic in veterinary medicine. Despite its efficacy in animal health, ENR is not approved for human use due to its associated toxicities. To address ENR detection, a sensor built upon a core-shell molecularly imprinted polymer (MIP) was created for the determination and testing of ENR in different matrices. Offering a miniaturized and reproducible tool for determining antibiotic residues in biological and environmental samples helps in revolutionizing the way we monitor and control antibiotic usage and contamination in various settings. The fabricated sensor demonstrated an optimum response time and functioned effectively across the pH range of 2.0 to 5.0. The potential profile displayed a linear correlation within a varying concentration spectrum of 1.0 × 10-5 M to 1.0 × 10-2 M characterized by a slope of 57.21 mV per decade. Furthermore, a comprehensive assessment of the environmental sustainability of the developed method was carried out using the Analytical Greenness calculator, AGREE algorithm. Lastly, an examination of the method's level of environmental friendliness was pursued using the newly developed RGB12 model to evaluate its "whiteness" level.

Global genomic epidemiology and transmission dynamics of plasmid-borne tmexCD-toprJ-carrying Klebsiella pneumoniae in a one health context.

The emergence of tmexCD-toprJ, a novel plasmid-mediated resistance-nodulation-division (RND) type efflux pump gene cluster, poses a significant threat to public health by diminishing bacterial susceptibility to the last-resort antibiotics, including tigecycline. Between 2020 and 2022, 18 Klebsiella pneumoniae strains carrying the tmexCD-toprJ gene were recovered from over 30,000 human stool samples collected from patients across five hospitals in China. Phylogenetic analysis of these 18 strains revealed clonal transmission of tmexCD-toprJ-carrying K. pneumoniae among patients and hospital settings. Comparative analysis of the 18 tmexCD-toprJ-carrying plasmids showed conservation in the genetic backgrounds of tmexCD-toprJ, despite the diverse backbone structures among the plasmids. The inactive suppressor, TNfxB1, is located in front of all tmexCD1-toprJ1, while TNfxB3 is located upstream of tmexCD3-toprJ3. Conjugation experiments demonstrated the transferability of plasmids from three strains to the recipient Escherichia coli J53. Among all 237 globally distributed tmexCD-toprJ-carrying strains, the majority (92.83 %) were from China. These strains encompassed 50 sequence types, with the most prevalent being ST11 (12.66 %), ST37 (11.81 %), and ST15 (11.39 %). Samples originated from various sources: 47.26 % from human, 38.82 % from livestock, and 13.08 % from the environment. The most common tmexCD-toprJ genotype was tmexCD1-toprJ1 (86.92 %, n = 206), followed by tmexCD2-toprJ2 (8.86 %, n = 21) and tmexCD3-toprJ3 (4.22 %, n = 10). The tmexCD1-toprJ1 gene was found in livestock (44.66 %, n = 92), humans (39.81 %, n = 82), and environmental samples (15.05 %, n = 31). In contrast, tmexCD2-toprJ2 and tmexCD3-toprJ3 were only found in human samples. Additionally, tmexCD-toprJ has been detected in 79 strains of K. pneumoniae harboring carbapenem-resistance genes. Given the presence of tmexCD-toprJ across various hosts and environments, establishing a comprehensive surveillance system from a One Health perspective is particularly vital.
