MiDOG is proud to announce that Dr. Mark Yacoub, PhD, has been awarded the Outstanding Presentation Award at the prestigious Microbial Dark Matter Symposium. This recognition underscores MiDOG’s role in advancing next-generation sequencing (NGS) as a powerful tool for both veterinary diagnostics and wildlife conservation.
The Microbial Dark Matter Symposium brings together microbiologists and data scientists from around the world to tackle the mysteries of the microbiota – what they call “microbial dark matter.” From exploring environmental microbiomes in remote ecosystems to developing novel testing approaches, every presentation showcased new ways to illuminate the unseen world of microbes.
MiDOG at the Symposium: Two Perspectives on Microbiome Science
Both Dr. Mark Yacoub and Dr. Kaylie Zapanta represented MiDOG at this year’s meeting, sharing research that demonstrates how NGS is reshaping microbial detection:
-
Dr. Kaylie Zapanta presented on how NGS can detect microbes even in low-biomass samples, a key advantage over culture or PCR when working with challenging or degraded material.
-
Dr. Mark Yacoub’s award-winning talk, “From Parasites to Phages – Metagenomic Exploration of the Fecal Microbiome in Eastern Indigo Snakes,” highlighted how whole-genome sequencing (WGS) and metagenomics can reveal the full microbial landscape, including bacteria, fungi, parasites, and viruses.
Breakthroughs in the Indigo Snake Study
Working with collaborators at Tulane University and the Central Florida Zoo’s Orianne Center for Indigo Conservation, Dr. Yacoub’s research achieved two field-defining firsts:
-
🧬 The first publicly available genome of Cryptosporidium serpentis (NCBI Accession: GCA_049309605.1)
-
🌍 The first comprehensive microbiome profile of wild and captive Eastern Indigo Snakes (Drymarchon couperi), a federally threatened apex predator
Why the Genome Matters
The new 6.5 Mb genome assembly (~85% complete) represents a milestone for reptile health. Unlike other Cryptosporidium species, C. serpentis infects the stomach, causing chronic gastric cryptosporidiosis in snakes, a disease with no consistently effective treatment.
With this reference genome, researchers and veterinarians can now:
-
Develop genome-informed diagnostics that outperform traditional PCR.
-
Compare C. serpentis with gastric-adapted species (C. muris, C. andersoni) to understand stomach-specific survival strategies.
-
Detect low-abundance parasite DNA in shotgun metagenomics workflows, improving disease surveillance in both wild and captive populations.

Key Findings from the Indigo Snake Study
By sequencing over 80 Eastern Indigo Snakes, the team uncovered:
-
Microbial shifts in infection: Significant changes across bacteria, fungi, protozoa, and phages.
-
Wild vs. captive differences: Wild snakes carried greater eukaryotic diversity, while captive snakes showed higher phage richness.
-
Zoonotic potential: Human-associated species (C. hominis and C. sp. chipmunk LX-2015) were detected exclusively in wild snakes.
These findings not only deepen our understanding of host–parasite–microbiome interactions but also offer new genomic tools for conservation management.
Recognizing Scientific Impact
The Outstanding Presentation Award highlights Dr. Yacoub’s excellence in research and communication, as well as MiDOG’s mission: bringing genome-level science to veterinary and conservation medicine.
Together, Dr. Yacoub and Dr. Zapanta’s work at the Microbial Dark Matter Symposium showcased how MiDOG is helping to illuminate the unseen microbiome—from low-biomass samples to complex wildlife infections, pushing diagnostics beyond panels and culture toward comprehensive, DNA-driven insights.
