Abstract :

Background: Non fermenter gram negative (NFGNB) have emerged as important pathogen responsible for hospital associated infections,as these bacilli show multi drug resistance , therefore it is important to correctly identify and know there antibiotic susceptibility pattern for better patient care.

Aim & objective of study:To isolate and identify non fermenter gram negative bacilli from various clinical isolates and to know the distribution pattern in various samples along with antibiotic susceptibility pattern of the isolates.

Material & method: NFGNB isolated from various clinical samples like pus, urine, blood and respiratory specimen which were receivedfor culture and sensitivity in Microbiology department at a tertiary care hospital were included in the study.

Results:Among 1566 clinical sample received, NFGNB isolates were 200(12.77%). .Among 200(12.77%) NFGNB isolates 95 (47.5%) isolates were from pus followed by 55 (27.5%) isolates from sputum, 23(11.5%) isolates from urine, 17 (8.5%) isolates from blood, 7(3.5%) isolates from endotracheal secretions and 3 (1.5%) isolates from pleural fluid.Out of 200 NFGNB isolates, Pseudomonas aeruginosa were the commonest organism constituting 112(56%) of the total isolates, followed by Acinetobacterbaumannii which constituted for 71 (35.5%) , Pseudomonas fluorescens– 7 isolates (3.5%), Acinetobacterlwoffii– 6 isolates (3%), Burkholderiacepacia complex –2 isolates (1%) and Sphingomonaspaucimobilis – 2 isolates (1%).Overall all NFGNB (n=200) showed high sensitivity to colistin 100%, imipenem 70.5%, amikacin 65.5% and piperacillin–tazobactam 64% however maximum resistance was noted for ciprofloxacin 61.5%. .
