Characterization of the translational attenuator of 20 methicillin-resistant, quinupristin/dalfopristin-resistant Staphylococcus aureus isolates with reduced susceptibility to glycopeptides.
Sir, Macrolide, lincosamide and streptogramin antibiotics are chemically distinct inhibitors of bacterial protein synthesis. Quinupristin/dalfopristin is a combination of streptogramin B and A compounds (SB/SA) with a synergic activity against most Gram-positive bacteria. Expression of MLS resistance in staphylococci may be constitutive or inducible. When expression is constitutive, the strains...
متن کاملOutbreak of methicillin-resistant Staphylococcus aureus with reduced susceptibility to glycopeptides in a Parisian hospital.
Epidemiological relationships were investigated between 40 methicillin-resistant Staphylococcus aureus (MRSA) strains with decreased glycopeptide susceptibility isolated from November 1998 to March 1999 from 39 patients (17 infected and 22 colonized patients) in nine wards of the Broussais Hospital, Paris, France. Reduced glycopeptide susceptibility was readily detected on brain heart infusion ...
متن کاملHigh percentage of methicillin-resistant Staphylococcus aureus isolates with reduced susceptibility to glycopeptides in The Netherlands.
While testing the in vitro activities of 14 antimicrobial agents against 107 methicillin-susceptible Staphylococcus aureus (MSSA) and 250 methicillin-resistant S. aureus (MRSA) isolates collected in The Netherlands, we found to our surprise that 19 (7.6%) MRSA isolates were suspected of having reduced susceptibilities to the glycopeptides when the Etest system (AB Biodisk, Solna, Sweden) was us...
متن کاملMethicillin Resistant Staphylococcus aureus
Etiology Staphylococcus aureus is a Gram positive, coagulase positive coccus in the family Staphylococcaceae. Methicillin-resistant S. aureus (MRSA) strains are resistant to methicillin and essentially all other beta-lactam antibiotics. MRSA isolates are genetically heterogeneous. 1 Some strains, which are called epidemic strains; are more prevalent and can spread within or between hospitals an...
متن کاملMethicillin Resistant Staphylococcus aureus
Staphylococcus aureus is an opportunistic pathogen often carried asymptomatically on the human body. Methicillin-resistant S. aureus (MRSA) strains have acquired a gene that makes them resistant to all beta-lactam antibiotics. Hospital-associated strains of this organism are serious nosocomial pathogens that have become resistant to most common antibiotics, and treatment can be challenging. Com...
