Introduction: Staphylococcus aureus is an important cause of severe infections in hospital and community and can cause significant mortality and morbidity in patients. In this study, the susceptibility and resistance pattern of Staphylococcus aureus to common antibiotics was investigated by disk diffusion, MIC (Minimal-inhibitory concentration) determination with E-test and D-test Methods: This...
The high prevalence of methicillin resistance among Staphylococcus aureus bacteremias leads to common use of vancomycin as empirical therapy. However, investigators have reported poor outcomes with vancomycin treatment for methicillin-susceptible Staphylococcus aureus bacteremia. We review the evidence supporting empirical combination of both vancomycin and a β-lactam agent for Staphylococcus a...
Eighty-nine Staphylococcus aureus strains were grouped according to their susceptibility or resistance to methicillin and oxacillin. The role of beta-lactamase in borderline methicillin resistance was confirmed by tests with beta-lactamase inhibitors, particularly when salt-supplemented medium was used. A penicillin-binding protein assay indicated that borderline methicillin-resistant S. aureus...
Background and Aims: Based on the results, Staphylococcus aureus is one of the serious infectious agents found in community and hospitals with remarkable potential for high morbidity and mortality around the globe. The present study was carried out for molecular investigation of methicillin-resistant Staphylococcus aureus strains and Staphylococcal Chromosomal Cassette mec (SCCmec) phenotypes i...
Staphylococcus aureus and Staphylococcus epidermidis strains isolated at eight large medical centers in Korea were examined for methicillin resistance and resistance to eight other antibiotics; cefazolin, cefamandole, cefuroxime, cefoxitin, cefotaxime, moxalactam, penicillin G and vancomycin. Methicillin resistance was found in 296 of 1225 strains (24.2%) of S. aureus and 126 of 348 strains (36...
Major challenges in diagnostic molecular microbiology are to develop a simple assay to distinguish Staphylococcus aureus from the less virulent but clinically important coagulase-negative staphylococci (CoNS) and to simultaneously determine their antibiotic resistance profiles. Multiplex PCR assays have been developed for the detection of methicillin- and mupirocin-resistant S. aureus and CoNS ...
background staphylococcus aureus is a major pathogen in hospital setting and in the community and causes a wide range of diseases. mrsa infection has recently become a serious problem in anti-microbial chemotherapy. the aim of the study was to detect and analyze the antibiotic diversity and isolation of methicillin resistance gene (meca) of s. aureus isolated from tehran hospitals as a rapid an...
We report characterization of a methicillin-susceptible, vancomycin-resistant bloodstream isolate of Staphylococcus aureus recovered from a patient in Brazil. Emergence of vancomycin resistance in methicillin-susceptible S. aureus would indicate that this resistance trait might be poised to disseminate more rapidly among S. aureus and represents a major public health threat.
Background and Objective: Efflux pumps are regarded as one of the most important mechanisms of antibiotic resistance in this era. Staphylococcus aureus is one of the bacterial groups with efflux pumps. The pumps’ activity is coded by specific genes. The aim of this study was to determine the phenotypic and molecular pattern of efflux pumps in the clinical isolates of methicillin-resistant...
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...
