Salicylic acid (SAL) has recently been shown to induce biofilm formation in Staphylococcus aureus and affect the expression of virulence factors. This study was aimed investigate effect SAL on regulatory agr system its impact S. formation. The quorum-sensing system, which is a central regulator pathogenicity, plays pivotal role dispersal mature biofilms contributes creation new colonization sites. Here, we demonstrate that impairs by interfering with expression. As revealed our work,...
Aspirin has provided clear benefits to human health. But salicylic acid (SAL) -the main aspirin biometabolite- exerts several effects on eukaryote and prokaryote cells. SAL can affect, for instance, the expression of Staphylococcus aureus virulence factors. also form complexes with iron cations it been shown that different chelating molecules diminished formation S. biofilm. The aim this study was elucidate whether content limitation caused by modify metabolism and/or metabolic regulators...
Staphylococcus aureus nasal carriage is a risk factor for individuals suffering from trauma, surgical procedures, invasive devices, and/or decreased immunity. Recently, we demonstrated that artificial colonization with an attenuated S. mutant reduced by bacterial interference the of pathogenic strains . This could be optional tool to diminish rate infections in hospitalized patients. The aim this study was construct safe Δ aroA and discriminate it colonizing osteomyelitis isolates Sma I...

ABSTRACT Acinetobacter baumannii is a human pathogen that frequently acquires antibiotic resistance genes leading to the emergence of multi-drug-resistant (MDR) strains. To investigate role transformation in acquisition determinants by this species, susceptible strain A118 was exposed genomic DNA carbapenem-resistant Klebsiella pneumoniae (CRKp). Resistant transformants were obtained and an increase level all β-lactam antibiotics observed. Whole genome analysis transformant clones...
