Summary

The talk, delivered by Sergio Camilo Malaver, a doctoral student, provides an introductory overview of metabarcoding applied to enteric parasites of public health importance. It begins by defining enteric parasites and their impact on hosts, including malnutrition, diarrhea, microbiota disruption, inflammation, and anemia. The presentation then contrasts traditional diagnostic methods like microscopy and coproparasitoscopy with molecular techniques such as PCR and metabarcoding, highlighting the advantages of metabarcoding in detecting multiple species simultaneously. Key steps in the metabarcoding workflow are detailed: sample collection and conservation (using ethanol, refrigeration, or DNA/RNA stabilizers), DNA extraction (with emphasis on quality, concentration, and integrity assessment), and the importance of choosing appropriate genetic markers and primers. The speaker shares insights from his own research on avian parasites, illustrating the practical application of these methods. The talk concludes with a discussion of bioinformatics analysis and the potential of metabarcoding to provide a comprehensive view of the eukaryotic microbiome, despite challenges such as cost and complexity.
