Nutritional Requirements of Staphylococcus aureus S-61

Staphylococcus aureus: methicillin-susceptible S. aureus to methicillin-resistant S. aureus and vancomycin-resistant S. aureus.

The evolution of methicillin-resistant and vancomycin-resistant Staphylococcus aureus has demanded serious review of antimicrobial use and development of new agents and revised approaches to prevent and overcome drug resistance. Depending on local conditions and patient risk factors, empirical therapy of suspected S. aureus infection may require coverage of drug-resistant organisms with newer a...

Reduced sensitivity of staphylococcus aureus to vancomycin

Introduction: Staphylococcus aureus is one of the most common causes of infections in hospitals and vancomycin is used for the treatment of methicillin resistant S, aureus infections. Therefore, imergence of Staphylococcus aureus with reduced sensitivity to vancomycin is a serious problem. The aim of this study was to investigate the prevalence of Staphylococcus aureus with reduced suscep...

Characterization of the s Regulon in Staphylococcus aureus

Emergence of Vancomycin-Intermediate Staphylococcus aureus and S. sciuri, Greece

and specific detection of verotoxin genes in Escherichia coli by the polymerase chain reaction. TE. Detection and characterization of the eae gene of Shiga-like toxin-producing Escherichia coli using polymerase chain reaction. To the Editor: Staphylococcal isolates with reduced susceptibility to glycopeptides, such as vancomycin and teicoplanin, are a serious public health problem because staph...

Teicoplanin Stress-Selected Mutations Increasing s Activity in Staphylococcus aureus

A natural rsbU mutant of Staphylococcus aureus, unable to activate the alternative transcription factor s via the RsbU pathway and therefore forming unpigmented colonies, produced first-step teicoplanin-resistant mutants upon selection for growth in the presence of teicoplanin, of which the majority were of an intense orange color. By using an asp23 promoter-luciferase fusion as an indicator, t...
