Cephalosporin-Resistant E. coli in Korean Livestock, 2010–2023

A 14-year longitudinal study (2010–2023) of third-generation cephalosporin-resistant Escherichia coli isolated from livestock in South Korea. The dataset, authored by Ji-In Kim and shared under CC-BY-4.0, documents resistance trends, genetic determinants like blaCTX-M-55, and multidrug resistance profiles. It was last updated on 2026-05 08.

Use Cases

• Analyze longitudinal trends of cephalosporin resistance in livestock based on the 14-year study period mentioned in the description
• Model the genetic determinants and plasmid-mediated transfer of resistance based on the described ESBL genotypes and mobile genetic elements
• Investigate co-resistance patterns to fluoroquinolones and colistin based on the reported multidrug resistance profiles
• Study the prevalence and evolution of specific E. coli lineages like ST752 and ST457 based on the multi-locus sequence typing results

Strengths

• Covers a 14-year longitudinal period from 2010 to 2023, providing a long-term view of resistance evolution
• Includes specific, quantified findings such as blaCTX-M-55 being the predominant variant in 52.3% (112/214) of isolates
• Reports on multidrug resistance, with 88.8% (190/214) of isolates exhibiting this phenotype
• Documents high genetic diversity and transferability of resistance determinants via IncF and IncI1 plasmids

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment for specific analytical tasks
• The data is contained in a DOCX file (721.8 KB), which is a small and potentially unstructured format for quantitative analysis
