Linezolid Resistance in Hungarian Poultry-Derived Enterococcus, 218 Isolates

218 poultry-derived Enterococcus isolates from Hungary were tested for linezolid resistance, with 36.2% classified as non-susceptible. The dataset integrates phenotypic minimum inhibitory concentration distributions with whole-genome sequencing results for 73 isolates. Ádám Kerek published this research data on figshare in May 2026.

Use Cases

• Analyzing phenotypic resistance distributions based on minimum inhibitory concentration (MIC) values and clinical breakpoints.
• Investigating genomic correlates of resistance based on the screening for transferable oxazolidinone resistance genes and target-site mutations.
• Assessing the prevalence of specific resistance mechanisms, such as the G2576T 23S rRNA substitution, within a targeted subset.
• Evaluating methodological differences in resistance interpretation based on the comparison of CLSI clinical breakpoints and EUCAST epidemiological classifications.

Strengths

• Includes 218 isolates with detailed linezolid minimum inhibitory concentration (MIC) values ranging from 0.015 to 512 μg/mL.
• Provides whole-genome sequencing data for a targeted subset of 73 isolates to link phenotypes with genomic markers.
• Applies dual interpretation frameworks (CLSI and EUCAST) for resistance categorization, enhancing methodological transparency.

Limitations

• The dataset is based on a resistance-enriched analytical subset, which the authors note is not designed for prevalence inference.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the primary Excel file is unknown, which may limit suitability assessment.

Collection Method

Isolates were collected from healthy broiler chicken and turkey farms across seven Hungarian regions, followed by broth microdilution testing and whole-genome sequencing.
