Coagulase-negative staphylococci (CoNS) are increasing in importance as causes of
hospital-acquired infections, particu-larly nosocomial bacteremias (64). The National …

Recent emergence of vancomycin resistance in methicillin-resistant Staphylococcus aureus
(VRSA) has posed a new threat to hospital infection control and antibiotic chemotherapy …

The surface of an indwelling medical device can be colonized by human pathogens that can
form biofilms and cause infections. In most cases, these biofilms are resistant to …

A highly vancomycin-resistant mutant (MIC= 100 microg/ml) of Staphylococcus aureus,
mutant VM, which was isolated in the laboratory by a step-pressure procedure, continued to …

▪ Abstract The emergence of Staphylococcus aureus resistant to vancomycin has caused
considerable concern. Such strains are currently rare, although they have been isolated …

In the last 5 years, clinical isolates of gram-positive bacteria with intrinsic or acquired
resistance to glycopeptide antibiotics have been encountered increasingly. In many of these …

Coagulase-negative staphylococci (CNS) were the first organisms in which acquired
glycopeptide resistance was recognized. Ever since the early reports, it has been apparent …

Of 41 methicillin-resistant coagulase-negative staphylococcal clinical isolates collected
during a 5-month period between late 1995 and early 1996, 28 showed tube dilution …

Abstract “Derivative isolates” with 4-to 8-fold and 8-to 16-fold increases in MICs of
vancomycin and teicoplanin, respectively, were selected from 2 susceptible clinical isolates …

ABSTRACT A series of 12 Staphylococcus aureus strains of various genetic backgrounds,
methicillin resistance levels, and autolytic activities were subjected to selection for the …
