Abstract:

Introduction: Antibiotic resistance among bacteria in particular those producing Extended Spectrum Beta lactamases (ESBLs)"nhas a very significant role in hospital acquired infections. Some of the gram negative bacilli including Klebsiella pneumonia"nand Escherichia coli are known to be ESBL producers which cause uncontrollable infections because they are also often"nresistant to other antimicrobial agents. This study was designed to assess the ESBL producing gram-negative bacilli among"nclinical isolates of inpatients at Shohada-ye Ashayer Hospital, Khorramabad, Iran."nMaterials and Methods: Samples were processed with routine laboratory methods and gram-negative bacilli were identified"nby standard tests. ESBL producing gram-negative bacilli were screened by MacConkey Agar containing 4 mg/liter ceftazidime"nand confirmed with the double disk synergy method."nResults: Fifty-three cases (23.6%) of 225 total isolated gram-negative bacilli were positive in terms of ESBL production."nKlebsiella pneumoniae comprising 20 cases (8.9%) was the dominant organism producing ESBLs followed by Escherichia"ncoli (10 cases; 4.4%) and Pseudomonas aeruginosa (10 cases; 4.4%). The most ESBL producing organisms were found in"nurine samples (21 cases; 39.6%). Ten cases (18.9%) of isolates were from samples collected with sterile bronchoscopy."nConclusion: Results of the study indicated that ESBL producing gram negative bacilli are frequently isolated from Shohadaye"nAshaier Hospital. Regarding the high resistance of these strains against many of the antibiotics and even against carbapenems,"nhealth care professionals need to plan policies to fight the induction and spread of such strains
