Whole-genome sequencing to explore genomic profile, pathogenicity, virulence motifs, and pangenome of clinical MRSA isolates.

ABSTRACT: Multidrug-resistant (MDR) and Methicillin-resistant Staphylococcus aureus (MRSA) are major opportunistic pathogens, particularly in healthcare settings. Despite the importance of such strains as a priority nosocomial pathogen, genomic data on Bangladeshi isolates remain limited. This study presents whole genome sequence (WGS) analysis of three MDR-MRSA strains (SA-18, SA-36, and SA-41) isolated from wound-infected patients in a tertiary care hospital in Bangladesh. Multi-locus sequence typing (MLST) identified SA-18 and SA-36 as sequence type ST6, and SA-41 as ST1930. All isolates carried the mecA gene and SCCmec type IVa were classified as MRSA. A total of 22 antibiotic resistance genes (ARGs) were identified, including blaZ, erm(C), norA, and sdrM. Pathogenicity prediction classified all
