introduction: one of the most important agents in hospital-acquired infections is staphylococcus aureus. treatment of methicillin-resistant s. aureus (mrsa) infections with decreased susceptibility to vancomycin has recently been more difficult. the aim of this study was to evaluate the possible presence of vancomycin intermediate s. aureus (visa) and vancomycin- resistant s. aureus (vrsa) and ...

staphylococcus aureus causes a wide variety of infections worldwide. methicillin-resistant s. aureus is one of most common causes of nosocomial and community acquired infections. the fluoroquinolones are an important class of antibiotics that used to treat infections caused by s. aureus. today, a significant increase in the rate of ciprofloxacin resistance in methicillin-resistant s. aureus str...

abstract        background and objective: staphylococcus aureus is the most common and important infectious agent. this bacterium can enter the bloodstream and cause some complications in the intensive care unit (icu).this organism can frequently be found in the nose and transmitted by the carriers. this study aimed to determine the efficiency of eradicating s. aureus from the nose of icu perso...

Intravascular infection due to Staphylococcus aureus requires colonization of subendothelium in the presence of shear forces. von Willebrand factor (VWF) is a large multimeric glycoprotein playing a key role in platelet adhesion to subendothelium. To determine whether VWF may also play a role in adhesion of S. aureus to endovascular sites, binding of VWF to S. aureus and adhesion of S. aureus t...

tigecycline is a new glycylcycline antibiotic structurally similar to minocycline antibiotic. it has broad spectrum activity, including staphylococcus aureus infections. this is the first study that evaluated the activity of tigecycline against staphylococcus aureus isolated from biological samples in iran. in vitro activity of tigecycline against 160 staphylococcus aureus including 99 methicil...

We report the complete genome sequence of the methicillin-sensitive Staphylococcus aureus (MSSA) strain FDA209P (ATCC 6538P and NCTC 7447).

S. aureus ID (bioMérieux, La Balme Les Grottes, France) is a new chromogenic agar medium designed to enable the isolation of staphylococci and the specific identification of Staphylococcus aureus. S. aureus produces green colonies on this medium due to production of alpha-glucosidase. To evaluate this medium, a total of 350 wound swabs were cultured onto S. aureus ID, CHROMagar Staph. aureus, a...

BACKGROUND Staphylococcus aureus alpha-toxin is a major virulence factor, but its mechanism of action in vivo is incompletely understood. METHODS We examined the role of alpha-toxin in S. aureus pneumonia using the mouse model of intranasal lung infection with S. aureus strain 8325-4 (hla(+) S. aureus) and an alpha-toxin-deficient mutant strain made on the 8325-4 background (hla(-) S. aureus)...
