Abstract:
OBJECTIVE To explore the positive rate of intercellular adhesion (ica) operon and its production- polysaccharide intercellular adhesion(PIA) and the relationship between the rate and adhesion of Staphylococcus epidermidis. METHODS Amplifying icaA of ica operon by PCR and then detecting it by agarose electrophoresis, detecting PIA by Congo red agar (CRA) to detect its adhesive ability by infusion set. RESULTS The icaA positive rate of S.epidermidis was 51.5%; the PIA positive rate was 50%; there was significant difference between the clone numbers of PIA positives and negatives (P
