Koirala Institute of Health and Sciences (BPKIHS), Dharan NepalAbstract Acinetobacter spp. is ubiquitous, aerobic gram-negative coccobacilli that are now emerging as an important nosocomial pathogen. In our study over a period of one year (January 2002- December 2002) at BPKIHS, a tertiary care hospital, from a total no. of 1089 isolates from pus/ aspirates of ICU, Burns, Orthopedic and other post operative wards, 146 isolates (13.4%) were Acinetobacter spp. Out of 146, 23 isolates of Acinetobacter spp. were sensitive to base line drugs. Remaining 123 strains of Acinetobacterspp. were resistant to Cefotaxime (99.2%), Ceftazidime (98.4%), Tobramicin (95.9%), Amikacin (96.7%), Netilmicin (89.43%), Ciprofloxacin (96.7%). Apart from these antibiotics none of the strains were sensitive to Piperacillin.en-USArticle
