Conclusion

One of the central goals in research within the One Health theme is to understand the complexity of direct and/or indirect factors that drive the dynamics of pathogens in ecosystems and facilitate spillovers between species^37,38,39. Although there are multiple connections between cancerous pathologies, infections and pathogen transmission⁹, to our knowledge, no study has attempted to link the two within a One Health perspective. Such concerns are nevertheless important because several human activities influence the prevalence of cancers in nature^11,12,14. In this work, we explored a key prediction proposed by Dujon et al.¹⁰—namely, that tumoral individuals within communities could play the role of symbiont amplifiers, increasing the likelihood of spillover to other species.

Our study provides the first preliminary evidence that tumoral individuals, at least in Hydra, could act as a super spreader of symbionts within and between species. Our findings confirm that tumoral hydras exhibit higher ciliate loads and demonstrate that they have a more pronounced spillover effect compared to healthy ones, although with different consequences according to the species introduced. While the reasons for the higher ciliate colonization of tumoral hydras remain unclear (see also²⁵), these results represent a first step towards full proof of concept, assessing the potential implications of tumor-induced vulnerability to infections for ecosystem functioning⁸. Further research using more complex experimental approaches is needed to understand the proximate mechanisms underlying the spillover effect of tumoral individuals and to generalize the results obtained to other models, thus exploring their ecological realism. By improving our understanding of these processes through the One Health approach, we can enhance strategies for managing disease transmission and preserving ecosystem stability in natural populations.

“… Clearly, addressing multi-host, zoonotic-origin outbreaks requires a cross-sectoral approach addressing human, animal, and ecosystem health. Such a “One Health” approach remains weak in the Proposal for the WHO Pandemic Agreement—with numerous caveats and few concrete mechanisms to prevent future zoonotic diseases from spilling over between wildlife, humans, and livestock. This is disappointing to say the least. …”

“A new six-year training program at the University of Guelph is set to prepare scientists for the inevitable: the next pandemic.

The course, co-lead by researchers at the university, will use the One Health approach to research and build capacity for a next pandemic in Canada.

The Canadian One Health Training Program on Emerging Zoonoses, or COHTPEZ, is the first training of its kind in the country. …”
