You can play around with the Shanghai dog MAG catalog here: sh-dog-mags.big-data-biology.org
where we added MAG basic information, ARGs annotation, and linked the 16S rRNA genes to MicrobeAtlas.
More data at Zenodo & ENA.

Using global dog gut microbiome data, we found that the living environment (household, colony, free-roaming) was the strongest factor shaping the gut microbiome composition.
(This is consistent with the mapping results: higher mapping rates for pet dog vs. non-pet dog cohorts)

In general, our species-level MAG representatives were more contiguous and had a higher quality than the reference genome assembly in public databases —especially regarding the presence of rRNA and mobile genetic elements, which are often missed in short-read assemblies.

Our Shanghai dog catalogs proved to be globally representative🌍: over 90% of reads (median value) from pet dog cohorts in Germany, South Africa, and the USA mapped to them.

Let's go to some of the main messages:
🧬We recovered 2,676 MAGs from Shanghai dogs, ~72% were near-finished (high-quality regarding MIMAG criteria) & highly contiguous.
⭕We recovered 185 circular extrachromosomal elements like plasmids and viruses from the same dogs.

Each stool sample was deeply sequenced 🐶💩: 20 Gbp Illumina short-reads + (at least) 20 Gbp Nanopore long-reads per dog. That's a substantial throughput for assembling MAGs from complex metagenomes🧬!

We started by sharing questionnaires via WeChat 📲 and then collected 💩 samples from 51 pet dogs across Shanghai 🐶. Along the way, we met many doggies (& their humans)!
