Abstract:
Objective To explore the biofilm forming ability and the ability to survive in stress environment of staphylococcus epidermidis strains isolated from catheters .Methods Semiquantitative biofilm assay and bacteria cell counting were performed to explore the biofilm forming ability and the ability to survive in stress environment of staphylococcus epidermidis strains .Results Staphylococcus epidermidis strain of 1457 and 5 clinical strains isolated from catheters had the similar ability of biofilm formation (P>0 .05) ,similar growth ability of planktonic and biofilm cells ,similar attachment ability to polystyrene ,similar ability to survive in an oxidative and ethanol stress environment (P>0 .05) .Conclusion The biofilm forming ability and the ability to survive in stress environment of staphylococcus epidermidis strains isolated from catheters were similar to staphylococcus epidermidis 1457 strain .
