- •The skin at the catheter insertion sites is the potential source infection.
- •Bacteria colonized in skin sites and matching catheters were clonally related.
- •The bacterial species isolated from catheter tips and skin sites were diverse.
- •Improved topical antiseptics and catheter care are crucial to prevent infection.
