<p><strong>Background:</strong> Bacterial colonization of central venous catheter (CVC) carries risk of developing catheter-related blood stream infections (CRBSI). The purpose of this study is to find out the frequency of colonization of CVC by different bacterial pathogens and their antibiotic sensitivity pattern.</p><p>Materials and Methods: A total of 53 CVC tip were received in one-year duration for culture and antibiotic sensitivity pattern. The isolated organisms were identified by standard microbiological procedure and subjected to antimicrobial sensitivity.</p><p><strong>Results:</strong> out of 53 CVC tip sent for culture and sensitivity, 21 (39.6%) showed significant growth. Out of 21 culture positive 52.3% were gram negative bacilli, 33.3% were gram positive cocci, 4.8% were Candida spp. Acenitobacter baumannii and Staphylococcus aureus were frequent pathogens isolated. Gram negative bacteria were less sensitive to antibiotics whereas gram positive bacteria were sensitive to Vancomycin.</p><p><strong>Conclusion:</strong> Though various organisms were isolated as colonizer of CVC, Acenitobacter baumannii is the most common colonizer. Antibiotic resistance has already emerged and represents a major problem. </p>
