Table 1_Significant strain microdiversity in mother-infant dyad cohorts across ethnic grou

54 mother-infant dyads from three ethnic groups across China were analyzed using full-length 16S rRNA, groEL, and tuf gene sequencing. The dataset, authored by Huimin Zhang and last updated in May 2026, compares strain-level diversity of Bifidobacterium communities. It supports findings of population-specific transmission patterns in gut symbiotic consortia.

Use Cases

• Compare strain similarity within and across cohorts based on the reported distribution patterns of ASVs.
• Assess biases in Bifidobacteria community profiling by comparing results from 16S rRNA versus groEL/tuf gene datasets.
• Investigate population specificity in intergenerational inheritance using the reported cohort-level strain similarity metrics.
• Identify a core group of bifidobacterial (sub)species present across multiple cohorts as described.

Strengths

• Data from 54 mother-infant dyads provides paired samples for transmission analysis.
• Analysis spans three ethnic groups across large geographic distances in China, offering population-level context.
• Uses multiple genetic markers (full-length 16S rRNA, groEL, tuf) for comparative taxonomic profiling.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The 410.4 KB file size suggests a limited scope, likely containing summary or processed results rather than raw sequence data.
