Comment on "Eco-epidemiology of gastrointestinal parasitic infections in captive chimpanzees in Gabon" by Mohamed-Djawad et al. (2025).

Mohamed-Djawad et al. (2025) provided an insightful eco-epidemiological analysis of gastrointestinal parasites in captive and semi-captive chimpanzees in Gabon, revealing important associations with abiotic factors and host traits. Here, we offer critical reflections on methodological aspects, suggest molecular approaches for zoonotic risk assessment, and raise questions regarding sampling design and behavioural ecology interpretations. Integration of quantitative parasitology, molecular diagnostics, and behavioural data could deepen understanding of parasite transmission dynamics, inform One Health surveillance, and enhance both chimpanzee welfare management and zoonotic disease prevention strategies.
