background and objective: methicillin resistance in staphylococcus aureus is an increasingly important clinical problem. a chromosomal gene, meca, mediates resistance to penicillinase-resistant penicillins such as methicillin and oxacillin in staphylococcus aureus. we evaluated the validity of disk diffusion test by using oxacillin, methicillin and cefoxitin disks with consideration of the pres...

Ceftobiprole is a novel broad-spectrum cephalosporin that binds with high affinity to PBP 2a, the methicillin-resistance determinant of staphylococci, and is active against methicillin- and vancomycin-resistant Staphylococcus aureus. Ceftobiprole was compared to vancomycin in a rabbit model of methicillin-resistant S. aureus aortic valve endocarditis. Ceftobiprole and vancomycin were equally ef...

Outbreaks of invasive methicillin-resistant Staphylococcus aureus infection within families are unusual. We investigated 2 family clusters of invasive methicillin-resistant Staphylococcus aureus infection, including 1 in which a young mother died of fulminant pneumonia. Although surveillance via culture of family contacts of patients with invasive methicillin-resistant Staphylococcus aureus inf...

An electronic surveillance network for monitoring antibiotic resistance in The Netherlands has been in operation since 1989. Seven public health laboratories participate and the system covers about 25% of all bacteriological determinations in The Netherlands. This paper reports the results of staphylococci isolated in the period 1989-1995. About 0.3% of the Staphylococcus aureus isolates in the...

ABSTRACT The emergence of livestock-associated methicillin-resistant Staphylococcus aureus strains (LA-MRSA) and the potential role pigs in evolution these has led to increased interest research microorganisms. However, this contributed a lack isolation characterization methicillin-susceptible S. (MSSA). In study, prevalence nursery finishing stages were analyzed. susceptibility profiles antibi...

PURPOSE OF REVIEW The scourge of community-acquired methicillin-resistant Staphylococcus aureus in pediatrics continues unabated. This review provides information on changes in epidemiology, therapeutic considerations, and measures to control the epidemic. RECENT FINDINGS The epidemiology and clinical manifestations of methicillin-resistant S. aureus have undergone important changes that pose...

Eight cephalosporins were tested for their activity against methicillin-susceptible and methicillin-resistant, coagulase-negative staphylococci and for their resistance to beta-lactamase from methicillin-resistant, coagulase-negative staphylococci. Susceptibility testing by the agar plate method was evaluated for the effect of inoculum size and duration of incubation. Methicillin-susceptible, c...

60 years following the primary isolation of the Oxford Staphylococcus. From an evolutionary perspective, it is noteworthy that members of this clonal lineage have subsequently acquired methicillin resistance [specifically following acquisition of the staphylococcal chromosome cassette mec (SCCmec) type IV element] and emerged as a community-associated MRSA strain (ST30MRSA-SCCmecIV) which has b...
