title: Enhanced susceptibility to subcutaneous abscess formation and persistent infection around catheters is associated with sustained interleukin-1beta levels.
abstract: A persistent Staphylococcus epidermidis infection in mice around a subcutaneous polyvinylpyrrolidone-grafted silicon elastomer catheter (SEpvp) but not around a conventional silicon elastomer catheter was observed. With SEpvp pericatheter tissue, protracted and exaggerated interleukin-1beta (IL-1beta) production was found. Apparently, sustained levels of IL-1beta are associated with enhanced susceptibility to biomaterial-associated S. epidermidis infection.
