Streptococcus Gallolyticus Genomic Analysis of 76 Strains

76 Streptococcus gallolyticus subsp. gallolyticus strains from diverse geographic and host origins were analyzed for genomic diversity and virulence determinants. Guadalupe Calderon published this dataset on figshare in May 2026. Systematic characterization identified five new subtypes of the type VII secretion system and a significant association with biofilm formation capacity.

Use Cases

• Identify dominant sequence types correlated with geographic origin based on multi locus sequence typing.
• Analyze the association between T7SS subtype and biofilm formation capacity.
• Expand the known repertoire of LXG domain-containing polymorphic toxins through genome-wide searches.
• Study the distribution patterns of LXG toxins across different bacterial strains.
• Perform phylogenetic reconstruction to understand lineage-associated variation in T7SS architecture.

Strengths

• Includes genomic data from 76 distinct bacterial strains.
• Identifies five new subtypes of the type VII secretion system.
• Demonstrates a significant association between T7SS subtype and biofilm formation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic or host-source bias inherent to the collection.
