Poultry-Derived Enterococcus Linezolid Resistance Data from Hungary

Hungarian poultry farms across seven regions contributed 969 Enterococcus spp. isolates, with a resistance-enriched subset of 218 isolates tested for linezolid susceptibility and a targeted subset of 73 isolates sequenced. The dataset, created by Ádám Kerek and last updated in May 2026, provides phenotypic minimum inhibitory concentrations and genomic screening results. It includes 79 linezolid non-susceptible isolates and identifies a 23S rRNA target-site mutation in seven sequenced samples.

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 resistance genes and target-site mutations.
• Assessing the prevalence of specific resistance mechanisms, such as the G2576T 23S rRNA substitution, within a poultry-derived bacterial population.
• Modeling the spread of linezolid non-susceptibility in agricultural settings based on isolate collection from multiple Hungarian regions.

Strengths

• Includes 218 isolates with broth microdilution test results for linezolid, providing a resistance-enriched analytical subset.
• Contains whole-genome sequencing data for a targeted subset of 73 isolates to screen for specific resistance determinants.
• Reports specific findings, including MIC50 of 2 μg/mL and the identification of the G2576T mutation in seven isolates.

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 described as an enrichment-based design not intended for prevalence inference, which may limit generalizability.

Collection Method

Isolates were collected from healthy broiler chicken and turkey farms, with phenotypic testing via broth microdilution and genomic analysis via whole-genome sequencing.
