Streptococcus Dysgalactiae Alpha-Like Protein Genes from Global Strain Collections

A global collection of 1,243 Streptococcus dysgalactiae genomes from human and animal origins in Norway, Japan, Canada, and Australia was screened for alp genes. The research, authored by Camilla Olaisen and last updated in April 2026, identified five novel alp genes and found alp prevalence in 18% of human and 10-15% of animal strains.

Use Cases

• Comparative genomics analysis based on the presence and diversity of alp genes across strains.
• Studying genetic heterogeneity and mosaicism in bacterial surface proteins based on described tandem repeat variations.
• Investigating the geographic distribution and prevalence of virulence factors based on data from Norway, Japan, Canada, and Australia.
• Analyzing the mobility of virulence genes based on the finding that alp genes reside on mobile genetic elements.

Strengths

• Includes 1,243 screened genomes, providing a substantial sample size.
• Long-read Nanopore sequencing was used on a subset of 32 strains to resolve complex repeat regions.
• Data covers a global geographic scope with strains from Norway, Japan, Canada, and Australia.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• The primary data file is a 205.1 KB PDF, which likely contains textual results rather than raw genomic data tables.
