While nosocomial infections by Staphylococcus epidermidis have gained much attention, this skin colonizer has apparently not evolved to cause disease, but maintain the commonly benign relationship with its host. Accordingly, S. epidermidis does not produce aggressive virulence g: estafilococo ‎| ‎Must include: ‎estafilococo. The epidemiology of Staphylococcus epidermidis in U.S. hospitals remains limited.

Amplicons were sequenced on both strands.

The ribosomal estafilococo epidermidis obtained were compared to those from wild-type S. In addition, seven linezolid-susceptible all with MIC values of 0. All selected strains were subjected to pulsed-field gel electrophoresis PFGE.

MLST was performed in all strains according to the methods published for S. STs were determined using estafilococo epidermidis S.

In accordance with the low virulence potential of S. Evasion of host defenses Pathogen survival estafilococo epidermidis the human body requires evasion of host defenses.


While a limited subset of host defense mechanisms such as antimicrobial peptides AMPs are present on estafilococo epidermidis human skin 12S. The estafilococo epidermidis immune system reacts first and in a rather non-specific way to any invading microorganism, including S.

For example, as a key part of innate host defense, neutrophils ingest bacteria and kill them using reactive oxygen species and AMPs The role of the specific, acquired immune response to S. The fact that our immune system has difficulties clearing long-lasting S. This may be due in part to S.

Furthermore, our immune system may have evolved not to react in a strong manner to prevalent colonizing bacteria. It can be given orally or parenterally in doses of to mg bid. estafilococo epidermidis

For infections involving oxacillin-resistant isolates or in penicillin-allergic patients, these agents may have certain advantages. Daptomycin, for example, may have the advantage of being bactericidal, for estafilococo epidermidis, in patients or neonates with persistent bacteremia Other new agents that are awaiting FDA approval include cephalosporins that bypass the abberant penicillin-binding protein causing oxacillin resistance ceftaroline and ceftobiprolelipoglycopeptides dalbavancin, telavancin and dihydrofolate reductase inhibitors icalprim.


Many estafilococo epidermidis these agents look very promising as agents that will be useful clinically against coagulase-negative staphylococci58, Ba cteremia The estafilococo epidermidis of bacteremia due to coagulase-negative staphylococci is also evolving.

Since almost all nosocomial bacteremias are due to oxacillin-resistant strains, vancomycin has been the keystone of therapy.

Now, however, clinicians feel more comfortable with newer, alternative agents, as we have hinted in previous sections. Very recent data suggest that for bacteremia, daptomycin may be a reasonable alternative, particularly in patients failing on previous therapy This is due primarily to the increasing use of intravascular and implanted prosthetic devices 1438 estafilococo epidermidis, Other populations at risk for coagulase-negative staphylococci bacteremia are the immunocompromised and low-birth weight, premature infants 67 Management of catheter related infections has traditionally included the removal of the infected line.

However, there is increasing evidence for conservative medical management when these infections are due to coagulase-negative staphylococci and especially when occurring in children 15,
