Adherence of staphylococcus aureus to catheter tubing inhibition by quaternary ammonium compounds.

Introduction: is a Gram positive bacterium which is responsible for a wide range of infections. This pathogen has also the ability to adhere to biotic or abiotic surface such as central venous catheter (CVC) and to produce a biofilm. The aim of this study was to evaluate the effect of hexadecyltrimethyl ammonium bromide (HTAB) and Hexadecylbetainate chloride (HBC) on adherence to the catheter tubing and on bacteria growth.
