E. coli Drug Resistance in Relict Gull Fecal Samples from Hongjian Nur, China

172 Escherichia coli strains were isolated from fecal samples of relict gulls (Larus relictus) in the Hongjian Nur area of Shaanxi Province, China. The dataset includes results from drug susceptibility testing, drug resistance gene detection via PCR, phylogenetic clustering, and multi-locus sequence typing. It was authored by Anwen He and uploaded to figshare on March 19, 2026.

Use Cases

• Analyze phenotypic resistance rates for antibiotics like azithromycin, ampicillin, and tetracycline based on drug susceptibility test results.
• Study the prevalence and distribution of specific drug resistance genes (e.g., tem, strA) based on PCR amplification results.
• Investigate phylogenetic relationships and multi-locus sequence types (e.g., ST4162, ST1299) of multi-drug resistant E. coli strains.
• Model the potential for migratory birds as reservoirs and transmitters of antibiotic resistance based on the high proportion of multiple drug resistance reported.

Strengths

• Contains specific phenotypic resistance rates: 37.21% for azithromycin, 12.21% for ampicillin, and 9.88% for tetracycline.
• Reports a quantified proportion of multiple drug resistance: 19.95% of the 172 strains.
• Provides precise detection rates for resistance genes, with the top five genes having carrying rates above 90% and tem and strA at 99.42%.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the single sampling location, Hongjian Nur.
