Fig. 2From: Staphylococcus aureus colonization in hemodialysis patients: a prospective 25 months observational studyNasal colonization density in patients dialyzed by an arteriovenous fistula (AVF) or a central venous catheter (CVC) from February 2016 to February 2018. About 1/3 of the cohort was dialyzed at least temporarily by a CVC. The number of colony forming units per milliliter (CFU/ml) is higher in patients with an AVF compared to the CVC cohortBack to article page
