analysis of pristinamycin-resistant staphylococcus epidermidis isolates responsible for an outbreak in a parisian 1990, over a 6-month period, an increase from 1 to 10% in the incidence of pristinamycin resistance among coagulase-negative staphylococci was observed in four intensive care units of a parisian hospital. twenty-three such isolates, as well as 25 pristinamycin-susceptible staphylococcus epidermidis isolates, were collected and typed by analyzing various bacterial constituents. two structurally related plasmids of 7.3 and 14.3 kb, carrying the gene vga encoding resistance to pristinamycin, wer ...19938257139
[action of teicoplanin on coagulase negative staphylococci in hospital units of the hospital hôtel-dieu in paris].teicoplanin, a glycopeptide antibiotic, is active against staphylococci, with the exception of some strains of coagulase negative staphylococci (scn). determination of the in vitro activity of teicoplanin by standard disk methodology is not sufficient, and has to be confirmed by the determination of the minimal inhibitory concentration (mic) for all strains presenting an inhibition zone diameter below 17 mm. we have studied during four months, the susceptibility of scn to teicoplanin isolated fr ...19938233626
an epidemiological assessment of coagulase-negative staphylococci from an intensive care unit.detection of an unusual combination of four resistance markers among coagulase-negative staphylococci (cns) isolated in the same intensive care unit led to the undertaking of an epidemiological assessment. seventeen cns isolates from the same unit and 38 epidemiologically unrelated staphylococcus epidermidis isolates were typed by eight methods, including analysis of immunoblot patterns and hybridisation patterns (hp) obtained with three probes. the probes comprised plasmids carrying the genes e ...19921588582
