Salmonella Kentucky Genomic Surveillance Data from Taiwan, 2004-2025

192 Salmonella Kentucky isolates were identified from 45,223 human Salmonella samples collected in Taiwan between 2004 and 2025, with a marked increase in 2024-2025. Whole-genome sequencing was performed on 165 isolates from humans, animals, and chicken meat, identifying three major sequence types. The dataset, authored by Ying-Shu Liao and last updated in June 2026, documents the emergence of azithromycin-resistant extensively drug-resistant (AziR-XDR) strains.

Use Cases

• Phylogenetic analysis of Salmonella Kentucky ST314 based on whole-genome sequencing data.
• Tracking the temporal and geographic spread of azithromycin-resistant extensively drug-resistant (AziR-XDR) strains mentioned in the surveillance.
• Comparative genomics to identify resistance genes and plasmid architectures like the IncFIB(pB171) plasmid.
• Assessing the genetic relatedness of Taiwanese isolates to international strains circulating in China and elsewhere.

Strengths

• Based on nationwide surveillance spanning 22 years (2004-2025).
• Includes whole-genome sequencing data for 165 isolates from multiple sources (humans, animals, food).
• Identifies a specific, high-risk clone (AziR-XDR ST314) with detailed resistance gene profiling.

Limitations

• Row count and column-level documentation are unknown, requiring manual inspection after download.
• The 5.2 MB size suggests the dataset is relatively small, which may limit some analyses.
• Data may reflect geographic and surveillance biases inherent to the Taiwanese sampling context.
