We report here the draft genome sequences of four vancomycin-intermediate Staphylococcus aureus (VISA) strains from South Korean hospitals participating in a nationwide laboratory surveillance program for vancomycin-intermediate and vancomycin-resistant Staphylococcus aureus All strains harbor mutations in the walKR, graSR, and/or rpoB genes that are known frequently mutated determinants of VISA.

Background: Sinusitis is a common respiratory infection increasingly associated with antibiotic-resistant Staphylococcus aureus, posing significant treatment challenges. The emergence of methicillin-resistant S. aureus (MRSA) in sinus infections necessitates comprehensive profiling of resistance patterns to guide effective therapy.

Microbial contamination of absorbable collagen membranes used in guided bone regeneration (GBR) may compromise healing outcomes. This study aimed to investigate whether the minimum inhibitory concentration (MIC) of hydrogen peroxide (HO) can improve the antibacterial effect of indocyanine green (ICG)-mediated antimicrobial photodynamic therapy (PDT) on absorbable collagen membranes while reducing the need for high HO concentrations. A laboratory-based model was developed using Streptococcus sanguinis and Staphylococcus aureus.

Purpose: Infective endocarditis (IE) has been associated with severe outcomes when complicated by diabetes mellitus (DM). We aimed to report characteristics, microbial etiology, and mortality for patients with IE stratified by DM from a nationwide cohort.
Methods: We used Danish registries, and patients with first-time IE (2010-2020) were stratified by DM.

Unlabelled: (SA) colonizes most mammals but also represents a danger in clinical settings because it evolves resistance against antibiotics, and SA infections represent a leading cause of death worldwide. SA nasal carriage provides the bacterial reservoir for opportunistic infection because clinical strains often match the patient's own nasally carried strain. The global SA carriage rate is typically reported as 25%-30% after sampling subjects once or twice and defining carrier status using culture-based methods.
