A Cross Sectional Study Characerization and Antimicrobial Susceptibility Pattern of Clinical Isolates of Acinetobacter at a Tertiary Health Care Teaching Hospital, Bhavnagar, Gujarat

Introduction: Acinetobacter is considered an important nosocomial pathogen because of its intrinsic as well as acquired antibiotic resistance. Hospital acquired infection is most common. The genus Acinetobacter consists of Gram negative, facultative aerobic organisms that are ovoid in shape and may appear as gram negative cocco-bacilli. This study conducted in a tertiary care centre from August 2014 to March 2016. Material and Method: Sample like blood pus and other body fluid are collected from 72 patients into wide mouth open sterile container. Samples processed by microscopy by wet mount and gram stain. Samples cultured on Mac Conkey and Blood Agar media by standard loop method for semi-quantitative culture and incubated aerobically for 24 hrs at 37C.Antibiotic sensitivity testing by Kirby Bauer method according to CLSI guidelines. Result: All 72 cases observed more commonly in patients with hospital admitted patients. Bacteria isolated included A.baumanii with a prevalence of 88.88%, followed by A. Lwoffii spp 11.11% were also isolated. Conclusion: Risk factor associated with nosocomial infections are associated with duration of hospital stay, more common among patients with catheterization and Mechanical ventilation, Surgical site infection subjects. Further, long term studies investigating the occurrence of complications in patients with XDR and PDR studies for studying the efficacy of antimicrobial therapy in preventing further complications in patients with Hospital acquired infections.
