Acinetobacter spp. have been implicated in recent years as an important nosocomial pathogen. They are being increasingly reported as the casual organism of numerous hospital outbreaks despite of their low pathogenic potential. Due to the confused taxonomic status the appreciation of the importance of the organism is lacking. Therefore the present study was made to type the Acinetobacter spp. by simple phenotypic identification schemes, to determine its resistance patterns and study of clinical demographic pattern. A study of clinical specimens received in Microbiology department, SCB Medical College, Cuttack over a period of one year(01-05-2015 to 01-07-2016). Identification Speciation and antibiotyping was performed from the clinical isolates of Acinetobacter was recovered from clinical samples. Clinical demographic pattern was studied retrospectively. Out of the total 1422 clinical isolates 158(9%) were Acinetobacter spp. The most common species was Acinetobacter baumannii 98(62%). Acinetobacter was predominantly isolated from pus samples 65(42.5%) followed by urine 46(29%) and respiratory samples 30(19%). The most effective antibiotic was Amikacin (78%) followed by Quinolones (73%) and most of the isolates were resident to Cephalosporins and Macrolides group of antibiotics. Multidrug resistant Acinetobacter infection has emerged as an increasing problem. The analysis of speciation and susceptibility pattern will be useful in proper identification and treatment.
