Metagenomics enables simultaneous detection of multiple microorganisms, including low-abundance parasites.
Current testing methods may miss unexpected pathogens due to reliance on microscopy and targeted PCR.
Standardized workflows and high-quality reference genomes are critical for reliable metagenomic results.
Metagenomics supports longitudinal monitoring of parasitic infections.
Population-scale surveillance can reveal geographic differences in parasite prevalence.

Use species-specific computational pipelines for detecting eukaryotic parasites.

Implement metagenomics alongside traditional methods for comprehensive parasite detection.

Challenges include contamination, sensitivity issues, and distinguishing clinically relevant findings from background noise.

Individuals undergoing testing for parasitic infections

Metagenomics may inform treatment decisions through improved detection of parasites.

Establish standardized workflows for sample collection, DNA extraction, and computational analysis.
Validate thresholds for identifying parasite subtypes to reduce false positives and negatives.
Incorporate proteomics to complement metagenomic findings.
