A protocol for mapping Blastocystis epidemiology and diagnostics from One Health perspective

Area of Science:

• Microbiology
• One Health
• Epidemiology

Background:

• Blastocystis is a globally prevalent gut protist affecting over a billion individuals worldwide.
• Its epidemiology, transmission dynamics, and clinical significance are not well understood.
• Current diagnostic practices lack standardization across different sectors.

Purpose of the Study:

• To initiate a large-scale mapping of Blastocystis epidemiology and diagnostic practices in Europe.
• To assess current diagnostic methodologies in clinical, veterinary, and environmental settings.
• To lay the groundwork for future research, standardization, and policy development.

Main Methods:

• The study outlines a protocol for assessing diagnostic methodologies for Blastocystis detection.
• It involves evaluating practices across clinical, veterinary, and environmental sectors.
• This forms the initial phase of the COST Action CA21105: Blastocystis under One Health.

Main Results:

• Key findings regarding current diagnostic approaches are highlighted.
• Challenges in Blastocystis detection and standardization are identified.
• A roadmap for improving detection methods is presented.

Conclusions:

• Standardizing Blastocystis diagnostics is crucial for understanding its global impact.
• This work will inform future research, policy, and microbial ecology studies.
• Improved detection methods are essential for public health and environmental surveillance.
