Analysis of the genotype and virulence of Staphylococcus epidermidis isolates from patients with infective endocarditis.
Staphylococcus epidermidis is one of the most common causes of infections of prosthetic heart valves (prosthetic valve endocarditis [PVE]) and an increasingly common cause of infections of native heart valves (native valve endocarditis [NVE]). While S. epidermidis typically causes indolent infections of prosthetic devices, including prosthetic valves and intravascular catheters, S. epidermidis ...
متن کاملRelated clones containing SCCmec type IV predominate among clinically significant Staphylococcus epidermidis isolates.
SCCmec is a mobile genetic element that carries the gene (mecA) mediating methicillin resistance in staphylococci. For Staphylococcus aureus, four SCCmec types have been described, one (type IV) of which has been associated with newly identified community-acquired methicillin-resistant S. aureus. However, the distribution of SCCmec types among S. epidermidis is not known. SCCmec typing of a col...
متن کاملAntibiotic therapy of experimental Staphylococcus epidermidis endocarditis.
Endocarditis was produced in rabbits with a methicillin-resistant Staphylococcus epidermidis isolate. Subpopulations resistant to other semisynthetic penicillins and cephalosporins were detected in the isolate. Their presence was probably responsible for the increase in minimum bactericidal concentrations and minimum inhibitory concentrations when tests with high inocula, rather than low inocul...
متن کاملPlasmid pattern analysis of Staphylococcal epidermidis isolates from patients with prosthetic valve endocarditis.
The electrophoretic pattern formed by individual bacterial plasmid DNA molecules of differing molecular size was evaluated as an epidemiological marker among isolates of Staphylococcus epidermidis from patients with prosthetic valve endocarditis (PVE). Purified covalently closed circular plasmid DNA was obtained from selected isolates, and 79% of the plasmids were found to be less than 10 megad...
متن کاملComparative epidemiology of Staphylococcus epidermidis isolates from patients with catheter-related bacteremia and from healthy volunteers.
Staphylococcus epidermidis is a major cause of catheter-related bloodstream infections (CRBSIs). Recent studies suggested the existence of well-adapted, highly resistant, hospital-associated S. epidermidis clones. The molecular epidemiology of S. epidermidis in Belgian hospitals and the Belgian community has not been explored yet. We compared a set of 33 S. epidermidis isolates causing CRBSI in...
