Identification and determination of the AST pattern of Acinetobacter species isolated from different clinical samples by VITEK circled2 Compact

IntroductionAcinetobacter is a highly diverse genus which includes a range of common pathogenic species such as A. baumannii, A. lwoffii etc. Acinetobacter species causes bacteremia, pneumonia, wound infections, Urinary tract infections in community as well as hospital settings. A. baumannii is one of the ESKAPE pathogen which makes it even more lethal as antibiotics cannot action on this. AimTo isolate Acinetobacter species from various clinical samples and to check their antimicrobial susceptibility pattern by VITEK {square} Compact in SGT Hospital, Gururam, Haryana. ResultsOut of total 6673 samples 595 were the positive isolates from which 35 were Acinetobacter isolates which were received from various wards of the hospital. Occurrence of Acinetobacter was seen more in males(57.14%) as compare to females (46.8%). A total of 31 strains were A. baumannii, 3 were A. lwoffi and 1 strain was of A. haemolyticus. Prominent presence of Acinetobacter was seen in Blood (48.57%) specimen along with pus(22.85%), endotracheal (22.85%), tracheal (2.85%) and eye swabs (2.85%). All the isolates were resistant to piperacillin/tazobactam (100%), ceftriazone (100%), amikacin (100%), gentamicin (100%) ciprofloxacin (91.42%), ceftazidime (91.42%), cefepime (88.57%), levofloxacin (88.57%) and trimethoprim/sulfamethoxazole (80%). Colistin susceptibility was observed in 88.57% of the isolates. ConclusionAcinetobacter is a common pathogen in hospital acquired as well as in community acquired infections as it is a opportunistic pathogen hence to identify the Acinetobacter species and to understand their antimicrobial resistance pattern this study was conducted.
