Draft genome sequences of three clinical isolates of teicoplanin-resistant Staphylococcus epidermidis from patients without prior exposure to glycopeptide antibiotics.

OBJECTIVES

The aim of this study was to analyse the DNA sequences of three teicoplanin-resistant Staphylococcus epidermidis isolates collected from patients not previously treated with glycopeptide antibiotics.

METHODS

The minimum inhibitory concentrations (MICs) of 12 antibiotics, including teicoplanin and vancomycin, were determined by the broth microdilution method. Genomic DNA was isolated, was sequenced by HiSeqX paired-end sequencing and was assembled into draft genome sequences using MyPro pipeline.

RESULTS

Analysis of the draft genome sequences demonstrated that the teicoplanin-resistant S. epidermidis isolates belonged to multilocus sequence typing (MLST) sequence types ST5 and ST87 and encoded multiple antimicrobial resistance genes, including the methicillin resistance gene mecA.

CONCLUSIONS

This report highlights the risk of dissemination of S. epidermidis strains resistant to a wide range of clinically important antibiotics.
