Accurate identification, isolation and antibiotic sensitivity pattern of non-fermenting gram-negative bacilli (NFGNB) is important for proper patient management. Aim: to find out the prevalence and the antibiotic sensitivity pattern of non- fermenters (NFs). A cross-sectional study was conducted on specimen collected from patients of tertiary care centre and send to microbiology laboratory for culture and sensitivity. Out of 4819 specimens collected in a year, 3363 (69.78%) were found culture positive and among them 378 (7.84%) were positive for NFGNB. Maximum percentage of NFs was from surgical wards (38.88%) followed by medical ICUs (24.07%) and surgical ICUs (21.69%). P. aeruginosa was the predominant isolate (47.88%) followed by A.baumannii (38.09%). Pus (37.83%) was the most common specimen shows growth of NFs followed by urine (16.93%), wound swab (16.40%), sputum (8.73%) and blood (8.20%). The antibacterial sensitivity pattern of NFGNB showed that isolated organisms were susceptible to higher generation of antibiotics, but showed some degree of resistance to routinely used drugs. NFGNB which was thought to be commensals or contaminants are now emerging as important nosocomial pathogens and keeping in mind the antibiotic sensitivity pattern, judicial use of antibiotics is required for management of concern infection.
