Identification of Carbapenem Resistance among Enterobacteriaceae Pathogens Isolated from Clinical Samples in Shendi locality

Abstract

Introduction: One of the most serious issues in medicine is the increasing resistance of Enterobacteriaceae to antimicrobial agent’s especially broad-spectrum antibiotics such as Cephalosporins and Penicillins. This fact is associated with higher mortality and morbidity rates, prolonged hospital stays, and increased treatment-related costs. Carbapenems are the last line for the treatment of infection caused by bacteria resistance to a broad spectrum of antibiotics. Objective: This study aimed to detect the Distribution of Carbepanems Resistance in Enterobacteriaceae Pathogens Isolated from Clinical Samples in the Shendi locality Method: Cross-sectional study and a laboratory-based study was carried out on 63 isolates from different specimens, 63 types of pathogenic bacteria were isolated and identified using Gram stain, biochemical reactions, and testing for their susceptibility to Carbapenems antibiotics was performed for all Enterobacteriaceae isolates. Result: The isolated Enterobacteriaceae comprising of 19.0(30.2%) E. coli, 17 (27.0%) K. pneumoniae, 13(20.6%) P. vulgaris, 5(7.9%) P. mirabilis, 1(1.6%) Enterobacter species, 3(4.8%) C.freundii and 5(7.9%) M. morganii.Carbapenem (Imipenem and meropenem) susceptibility testing showed that 36.0% of Enterobacteriaceae isolates were Carbapenem resistant.Conclusions: The study revealed the low resistance pattern of Enterobacteriaceae to Carbapenems. Despite that E. coli (19.0, 30.0%) was the most isolated organism, K. pneumonniae (7.0, 11.0%) was the most resistant isolate to Carbapenems. The urine sample had the highest degree of resistance. There was a correlation between patients with chronic diseases such as cancer and the resistance level to Carbapenems, while there was no statistical significance between the period of antibiotics usage and the degree of resistance.
