Table 6: Infection prevention in the tissue samples: the total number of samples where significant (≥3.0 Log) bacterial load was recovered (from sample locations 4, 6, 8, and 10) is divided by the total number of catheters/tracts in each group. This is separated by sample type (tissue and catheter).
