Abstract

Clinical isolates of Staphylococcus epidermidis are frequently referred to produce a biofilm, known as slime, involved in adherence to medical devices and in resistance to host defences. A high frequency of slime producing Staphylococcus aureus strains was never reported, at least in the case of human isolates. In the present study the production of slime by clinical isolates of S. aureus and S. epidermidis from catheter associated infections and from post-surgical infections was studied by a sensitive method based on culturing the isolates on Congo red agar. The study demonstrates that in nosocomial surgical infections, considered separately from catheter-associated infections, S. aureus emerges as a more prevalent etiologic agent than S. epidermidis, with a proportion of slime producing strains markedly high.
