HN-01560099_Evaluation of Antibiotic Resistance of Escherichia Coli Strains Isolated from ICU Enteral Nutrition

The widespread use of antimicrobial agents and lack of infection control procedures, is the main cause of the current antimicrobial resistance in human pathogens. The use of antimicrobials in food animal production also influences, because resistance genes can spread from animals to humans by food chain, so If the environment of hospital has been infected, hospitalized patients are at a high risk of this dangerous infection because of their weak immune system, so that is a sever risk for their health. Our aim was to explore the antibiotic resistance of Escherichia coli strains isolated from enteral feedings. 40 samples of enteral feedings were collected from Tabriz Imam Reza hospital. Samples were diluted from 10-1 to 10-6 and were cultured on MacConkey agar by pour plate method and incubated in 37 C° for 48 hours. Typical colonies randomly selected and streaked onto blood agar medium.13 samples were positive for E.coli. The minimum inhibitory concentration (MIC) test was used to find the resistance level for 4 antibiotics. Isolates were resistant to Amoxicillin 26%, Tetracycline 23%, Chloramphenicol 23% and Ceftriaxone 7%. Monitoring of antibiotic-resistance patterns and preparation of reliable strategies may lead to enhanced results for inhibition and control of E. coli infections in patients receiving enteral feeding.
