Introduction: Acinetobacter Sp. are ubiquitous aerobic gram negative coccobacilli that are increasingly responsible for a large number of nosocomial infections. It represents severe problems for choosing effective antimicrobials because of the resistance to many available drugs. Materials and Methods: Specimens collected from ICU patients were cultured and identified as Acinetobacter Sp. using standard methods. Antibiotic sensitivity pattern was done using modified Kirby Bauer disc diffusion method. Results: Two hundred and eleven isolates of various bacteria from 200 patients with nosocomial infections were collected and evaluated. A total of 38 (18%) isolates of Acinetobacter Sp. were isolated. The prevalence was more among males in all age groups. Multidrug resistance isolate showing resistance to two or more antibiotics was 94.7% (36). Imipenem (60.5%) and Cefaperazone/Sulbactum (50%) showed highest sensitivity. Poor sensitivity was seen with Amikacin (73.6%), Ampicillin (86.8%) and Gentamicin (52.6%). Conclusion: Acinetobacter Sp. is a formidable challenge for managing critically ill people. Continued efforts are needed to develop better antimicrobial policies against this pathogen. |
