Organising for One Health in a developing country

Putting one health to the test: Operational challenges and critical reflections from the global South

One Health as a policy framework to tackle zoonoses has gained wide-ranging validation with multiple international organizations throwing their collective might behind it. Such endorsement has convinced several governments to adopt One Health as a national strategy to address zoonoses. Although some argue that One Health is so many things that there are in fact multiple 'One Healths', others find that most international policy documents that use the One Health framing contain certain key recommendations, with intersectoral coordination and disease surveillance prominent among them. In this paper we examine whether and how One Health travels in a sub-national setting in a developing country context such as that of India, with particular focus on intersectoral coordination. We draw on documentary analysis, semi-structured interviews, and workshops with government officials across key sectoral agencies at the district level, to understand prevalent institutional mechanisms in place to address zoonoses in such a setting. We locate our study in the district of Gyalshing in the state of Sikkim in India, which is a potential zoonoses 'hotspot' given its location within the biodiverse Indian Himalayan Region, with numerous avenues for human-animal interactions, and burgeoning human population linked to its tourism-run economy. We outline successful cases where certain zoonotic diseases could be tackled, while also highlighting structural constraints that need to be borne in mind while planning or advocating One Health as a blanket policy prescription. In doing so, we draw attention to the political dimensions of global health policies, and question whether One Health can be uncritically deployed in developing country contexts.

Molecular and Epidemiological Characterization of ESBL-producing Escherichia coli from Captive Wild Birds in Zoological Gardens in Nigeria

Aim

This study aimed to characterize ESBL-producing E. coli isolates obtained from apparently healthy captive wild birds from selected zoological gardens in Nigeria.

Materials and Methods

A total of 121 freshly deposited faecal samples were collected from captive wild birds in seven major zoological gardens and pooled into 50 samples. The samples were screened for the presence of E. coli. The isolates obtained were tested against a panel of antibiotics and screened for ESBL production using the double disc synergy test (DDST). Primer-specific PCR was used to detect the carriage of ESBL genes (bla CTX-M, bla TEM and bla SHV) by the isolates.

Results

A total of 26 ESBL-producing E. coli isolates (52%, n = 26/50) were obtained from the pooled faecal samples of captive wild birds. The highest resistance rate to antibiotics was observed with amoxicillin-clavulanate (88.5%), while the lowest resistance rate was observed with fosfomycin (3.8%). The isolates had Multiple Antibiotic Resistance Index (MARI) values ranging from 0.1 to 0.8 across the tested antibiotics. Approximately 65.4% of the isolates carried bla CTX-M, while bla TEM and bla SHV were detected in 15.4% and 34.6% of the isolates, respectively.

Conclusion

This study revealed a significant prevalence of ESBL-producing E. coli in captive wild birds in Nigeria and highlighted the need to institute control measures in zoological gardens to prevent the transmission of antibiotic resistance.

Global Mapping and Visualization Analysis of One Health Knowledge in the COVID-19 Context

Globally, the COVID-19 pandemic had a significant impact on the health, social, and economic systems, triggering lasting damage and exposing the complexity of the problem beyond just being a health emergency. This crisis has highlighted the need for a comprehensive and collaborative strategy to successfully counter infectious diseases and other global challenges. With the COVID-19 pandemic pushing One Health to the forefront of global health and sustainable development agendas, this concept has emerged as a potential approach for addressing these challenges. In the context of COVID-19, this study investigates global knowledge about One Health by examining its state, significant contributions, and future directions. It seeks to offer an integrated framework of insights guiding the development of well-informed decisions. A comprehensive search using the Scopus database was conducted, employing specific terms related to One Health and COVID-19. VOSviewer 1.6.19 software was used to generate network visualization maps. Countries' research output was adjusted based on their gross domestic product (GDP) and population size. The study identified a total of 527 publications. The United States led with 134 documents (25.4%), but India topped the adjusted ranking. One Health journal stood as the most common outlet for disseminating knowledge (49 documents; 9.3%), while Centers for Disease Control and Prevention (CDC), the United States emerged as the most prolific institution (13 documents; 2.5%). Key topics were related to the virus transmission mechanisms, climate change impacts, antimicrobial resistance, ecosystem health, preparedness, collaboration, community engagement, and developing of efficient surveillance systems. The study emphasizes how critical it is to capitalize on the present momentum of COVID-19 to advance One Health concepts. Integrating social and environmental sciences, and a variety of professions for better interaction and collaboration is crucial. Additionally, increased funding for developing countries, and legislative empowerment are vital to advance One Health and boost disease prevention.

Analyzing One Health governance and implementation challenges in Mexico

Establishing a robust One Health (OH) governance is essential for ensuring effective coordination and collaboration among human, animal, and environmental health sectors to prevent and address complex health challenges like zoonoses or antimicrobial resistance. This study conducted a mixed-methods environmental scan to assess to what extent Mexico displays a OH governance and identify opportunities for improvement. Through documentary analysis, the study mapped OH national-level governance elements: infrastructure, multi-level regulations, leadership, multi-coordination mechanisms (MCMs), and financial and OH-trained human resources. Key informant interviews provided insights into enablers, barriers, and recommendations to enhance a OH governance. Findings reveal that Mexico has sector-specific governance elements: institutions, surveillance systems and laboratories, laws, and policies. However, the absence of a OH governmental body poses a challenge. Identified barriers include implementation challenges, non-harmonised legal frameworks, and limited intersectoral information exchange. Enablers include formal and ad hoc MCMs, OH-oriented policies, and educational initiatives. Like other middle-income countries in the region, institutionalising a OH governance in Mexico, may require a OH-specific framework and governing body, infrastructure rearrangements, and policy harmonisation. Strengthening coordination mechanisms, training OH professionals, and ensuring data-sharing surveillance systems are essential steps toward successful implementation, with adequate funding being a relevant factor.
