Summary
# Editorial Summary: Proteomics of Trypanosoma evansi Infection Surra, caused by the protozoan parasite *Trypanosoma evansi*, presents a significant economic burden to the livestock industry, particularly affecting equines, camels and donkeys, yet diagnostic and therapeutic options remain severely limited—with no WHO-approved tests or vaccines available and existing medications demonstrating considerable toxicity. To address this knowledge gap, Roy *et al.* employed mass spectrometry-based proteomics to characterise the clinical proteome of *T. evansi* infection in a rodent model, taking advantage of recent technological advances in protein identification that have not yet been systematically applied to this neglected pathogen. The proteomic analysis identified key parasite-derived and host-response proteins that could serve as potential diagnostic biomarkers and therapeutic targets, generating molecular data that may accelerate the development of improved diagnostic protocols and treatment strategies. These findings carry direct relevance for equine practitioners, as the proteomic signatures characterised could inform the development of more sensitive diagnostic assays and inform rational drug development efforts—particularly important given the parasite's emerging zoonotic potential and the continuing limitations of current clinical tools. The work highlights the value of applying modern molecular approaches to economically important parasitic diseases of horses, offering a foundation upon which improved diagnostic and control measures can be built.

Practical Takeaways
- •This research contributes to developing improved diagnostic methods for surra, which affects equines, camels, and donkeys—important for early detection in affected populations
- •Findings may eventually lead to better drug targets and treatment options, addressing current drug toxicity issues in surra management
- •Equine practitioners in endemic regions should be aware that improved diagnostics from such research may become available to support surra identification and control
Key Findings
- •Proteomics analysis using mass spectrometry identified potential diagnostic markers for T. evansi infection
- •Study addresses gap in knowledge regarding T. evansi pathophysiology compared to related parasites T. brucei and T. cruzi
- •No established WHO diagnostic tests or effective vaccines currently available for surra in livestock
