Genomic Sequence of a Clinical Vancomycin-Resistant Reference Strain, Enterococcus faecalis ATCC 51299

Area of Science:

• Microbiology
• Genomics
• Antimicrobial Resistance

Background:

• Enterococcus faecalis is an opportunistic pathogen.
• Accurate antibiotic susceptibility testing is crucial for effective treatment.
• Reference strains are essential for quality control in clinical microbiology.

Purpose of the Study:

• To generate a draft genome sequence of Enterococcus faecalis ATCC 51299.
• To provide a high-quality reference genome for antimicrobial resistance studies.
• To characterize the genetic basis of antibiotic resistance in this strain.

Main Methods:

• Whole-genome sequencing was performed on Enterococcus faecalis ATCC 51299.
• Bioinformatic analyses were used to assemble and annotate the genome.
• Multilocus sequencing typing (MLST) was conducted.

Main Results:

• A draft genome sequence for Enterococcus faecalis ATCC 51299 (MLST ST6) was obtained.
• The strain exhibits sensitivity to teicoplanin and resistance to vancomycin.
• The vanB gene, a vancomycin resistance marker, was identified.

Conclusions:

• The genome sequence provides a valuable resource for Enterococcus faecalis research.
