Abstract

Nosocomial infections are the fourth leading cause of death. About 60-70% of nosocomial infections are associated with some type of implanted medical device. When microorganisms gain access to the intraluminal or extraluminal surface of the catheter, they become irreversibly adherent and provides a protective environment against the host defenses and antibiotics. The present study was carried out to look for the pattern of microorganisms causing Catheter-related infections. Samples analyzed were intravascular catheters, Foley’s catheters, blood and urine samples. A total of 106 catheter samples obtained from 105 patients were studied. Samples were processed as per standard methods. Out of 105 cases, maximum number of samples were from neonates. A total of 53 organisms were isolated, Out of which, 41 were isolated from IVC and 12 from urinary catheters. The commonest organism colonizing IVC were Candida spp. (73.1%), CONS (19.5%) and Klebsiella spp. (4.8%). Urinary catheter samples were commonly colonized with CONS (25%), P. aeruginosa and Acinetobacter spp. (16.6%).
