A vancomycin-resistant Gram-positive bacterium of the genus Enterococcus, designated as BT22, was isolated from untreated hospital effluents at Chettia Chlef Hospital. The complete genome of strain BT22 was sequenced using the Illumina MiSeq platform, revealing a total length of 2,577,707 bp, with 2462 coding sequences (CDS) and an average G+C content of 38.00 mol%. Phylogenomic analyses confirmed that strain BT22 belongs to the same species as Enterococcus faecium AVS0243, with a similarity of 99.79 %. The study identified 12 antibiotic resistance genes and one virulence gene in strain BT22. These genes confer resistance to various classes of antibiotics, including aminoglycosides, macrolides, tetracyclines, and vancomycin. However, the virulence gene identified codes for adhesion. Furthermore, mobile genetic elements, such as IS elements carried by a conjugative plasmid, were detected. The genomic sequencing data of E. faecium BT22 will be of great value to the scientific community, enabling comparative genomic analyses and a better understanding of antibiotic resistance mechanisms, particularly towards vancomycin. The genomic information has been deposited in the DDBJ/EMBL/GenBank databases under accession number JASSVD010000000, providing an essential resource in the fight against antibiotic resistance and the spread of resistant bacterial strains. |
