Table 2_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 data, authored by Huimin Zhang and last updated in May 2026, reveals significant strain-level microdiversity and population-specific patterns in the transmission of gut Bifidobacteria.

Use Cases

• Compare strain-level diversity based on full-length 16S rRNA versus single-copy gene (groEL/tuf) sequencing methods mentioned in the description
• Analyze population specificity in gut symbiont inheritance based on cohort-level strain similarity patterns
• Identify core bifidobacterial (sub)species present across multiple ethnic cohorts as described

Strengths

• Includes data from 54 mother-infant pairs across three distinct ethnic groups
• Compares results from three different genetic markers (full-length 16S rRNA, groEL, tuf)
• Identifies a core group of at least 10 bifidobacterial (sub)species consistently across cohorts

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data is contained in a 1.2 MB DOCX file, which may require extraction and formatting for analysis
