- Group 1, blood isolates obtained from patients’ IV line; Group 2, nasal isolates of healthy volunteers; Group 3, nasal isolates of the same patients in Group 1; Group 4, nasal isolates of ICU staff. △Values are given as slime production of S. epidermidis strains vs first group (p<0.05), ◇Values are given as slime production of S. epidermidis strains vs first group (p<0.001). There was no statistical difference among other three groups (P>0.05).
