Abstract:
We report the draft genome of multidrug-resistant Escherichia coli UA1 from Kosovo retail chicken liver, revealing ARGs (blaEC-18, blaCTX-M-55, and dfrA36), virulence genes, and plasmids. Assembled into 86 contigs and 214 scaffolds, it highlights antimicrobial resistance dissemination in the food chain.
Insights
The draft genome of multidrug-resistant Escherichia coli UA1 was sequenced from chicken liver. This study reveals key antimicrobial resistance genes and plasmids, highlighting food chain contamination risks.
Area of Science:
- Microbiology
- Genomics
- Food Safety
Background:
- Multidrug-resistant bacteria pose a significant threat to public health.
- The food chain is a potential reservoir and transmission route for antimicrobial resistance.
Purpose of the Study:
- To sequence and analyze the draft genome of multidrug-resistant Escherichia coli UA1.
- To identify antimicrobial resistance genes (ARGs) and plasmids within the isolate.
- To understand the dissemination of antimicrobial resistance in the food chain.
Main Methods:
- Whole-genome sequencing of Escherichia coli UA1.
- Bioinformatic analysis for genome assembly and gene identification.
- Identification of antimicrobial resistance genes and plasmid sequences.
Main Results:
- The draft genome of Escherichia coli UA1 was assembled into 86 contigs and 214 scaffolds.
- Key ARGs including blaEC-18, blaCTX-M-55, and dfrA36 were identified.
- Presence of virulence genes and plasmids associated with antimicrobial resistance was confirmed.
Conclusions:
- The genome data provides insights into the genetic basis of multidrug resistance in this E. coli strain.
- The findings underscore the importance of monitoring antimicrobial resistance in food products.
- Retail chicken liver can harbor multidrug-resistant bacteria, indicating potential food chain contamination.
