Streptococcus Dysgalactiae Alp Gene Prevalence and Diversity in Global Strains

Camilla Olaisen's dataset, last updated April 10, 2026, presents findings from screening 1,243 Streptococcus dysgalactiae genomes for Alpha-like protein (Alp) genes. It includes results from global strain collections from Norway, Japan, Canada, and Australia, with detailed analysis of 32 Norwegian strains sequenced via Nanopore technology. The data reveals the prevalence, genetic heterogeneity, and distribution of Alp genes across human and animal strains.

Use Cases

• Analyze geographic differences in Alp gene prevalence based on strain origin data.
• Study genetic heterogeneity and mosaicism in Alp genes based on sequence variation findings.
• Investigate the association between Alp genes and mobile genetic elements based on described genomic context.
• Compare Alp gene distribution between human and animal host strains based on reported prevalence percentages.

Strengths

• Data is derived from screening 1,243 S. dysgalactiae genomes, providing a substantial sample size.
• Includes long-read sequencing data from 32 strains to resolve complex tandem repeat regions.
• Covers strains from four distinct geographic regions: Norway, Japan, Canada, and Australia.
• Reports specific prevalence figures: 18% in human strains and 10-15% in animal strains.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small at 115.7 KB, indicating limited scope or summary-level data.
