Protocol for detection of biofilms on needleless connectors attached to central venous catheters

J Clin Microbiol. 2001 Feb;39(2):750-3. doi: 10.1128/JCM.39.2.750-753.2001.

Abstract

Central venous catheter needleless connectors (NCs) have been shown to develop microbial contamination. A protocol was developed for the collection, processing, and examination of NCs to detect and measure biofilms on these devices. Sixty-three percent of 24 NCs collected from a bone marrow transplant center contained biofilms comprised primarily of coagulase-negative staphylococci.
