Staphylococcus aureus is a major human pathogen responsible for severe infections. While traditionally described as extracellular, increasing evidence establishes S. aureus as a facultative intracellular pathogen. Intracellularity contributes to immune evasion, dissemination, and antibiotic failu...

The global proliferation of methicillin-resistant Staphylococcus aureus (MRSA) persists as a significant contributor to challenging infections, highlighting the urgent necessity for therapies that utilize novel mechanisms. Aspartate transcarbamoylase (ATCase), which catalyzes the initial committe...

Approximatively 75% of the genome of S. aureus (“core” genome) are highly conserved between strains, whereas the remaining 25% (“accessory” genome) are composed of variable regions that are mostly composed of mobile genetic elements (MGE), containing virulence and resistance genes. We have developed...

Analysis of the intergenic regions of Staphylococcus aureus by bioinformatics predicted multiple regulatory regions. From this analysis, we also characterized 11 novel noncoding RNAs (RsaA-K) that are expressed in several S. aureus strains under different experimental conditions. Many of them accumu...

Subinhibitory concentrations of the neuroleptic drug thioridazine (TDZ) are well-known to enhance the killing of methicillin-resistant S. aureus (MRSA) by β-lactam antibiotics, however, the mechanism underlying the synergy between TDZ and β-lactams is not fully understood. In the present study we ...

Novel anti-infective agents targeting Staphylococcus aureus and capable of increasing S. aureus susceptibility towards antibiotics are needed. One alternative approach is targeting the bacterial quorum sensing (QS) system. QS is a process by which bacteria produce and detect signal molecules and the...

Staphylococcus aureus is a major human pathogen and resistant to numerous clinically used antibiotics. The first antibiotic developed for S. aureus infections was the nonribosomal petide secondary metabolite penicillin. We discovered cryptic nonribosomal peptide secondary metabolites, the aureusimi...

Precisely targeting a biomolecule within living systems could create unique opportunities at the biology-medicine interface. Such methods have been non-trivial due to the complex selectivity attributes. Here, we introduce an electronically tunable chemical technology that targets N-terminal glycine,...

Multi-drug resistant Staphylococcus aureus (S. aureus) infections continously threaten public health. The rapid escalation in morbidity and mortality rates associated with methicillin-resistant S. aureus (MRSA) infections necessitates the urgent development of novel antimicrobial agents. Our study r...

Staphylococcus aureus strain MW2 was exposed to the following neutrophil microbicides, hydrogen peroxide (H2O2), hypochlorous acid (HOCl) and azurophilic granule proteins. At the indicated time points, bacterial cultures were centrifuged and bacteria were lysed with RLT buffer (Qiagen) using a Fast...
