Polyclonal Staphylococcus epidermidis intravascular catheter-related infections.
During a 4-month period we prospectively investigated the frequency of polyclonal catheter infections with Staphylococcus epidermidis. Of each catheter with pure growth of S. epidermidis, six colonies were genotypically analyzed with pulsed-field gel electrophoresis. Two out of 12 patients with catheter infection had a polyclonal infection. Both clones of each catheter had a clearly different antibiotic susceptibility. This study shows that polyclonal catheter infections are not exceptional. Further studies are needed to define the clinical consequences of polyclonal catheter infection.
