Abstract :
Today, microorganisms have become resistant to drugs by causing genetic mutations. The aim of this study was to determine the antibiotic resistance of gram-negative bacteria isolated from urine culture in the laboratory of Savadkuh city. The cross-sectional descriptive study was performed on gram-negative bacteria isolated from urinary tract infections in Savadkuh laboratory. Bacterial isolates were identified by microscopic examination, morphology and biochemical tests. Fifty samples of gram-negative bacteria causing urinary tract infections were isolated from 5 cases (10%) of men and 45 cases (90%) of women. According to the study, the two most common gram-negative bacteria in urinary tract infections are based on the percentage of infectivity in this study, which include: E.Coli (62%), and Klebsiella (30%) and other gram-negative (8%), They were isolated from urine samples. According to the antibiogram test, the most cases of resistance were related to the antibiotics ampicillin, nalidixic acid and cefazolin, respectively. On the other hand, the most sensitive drugs are nitrofurantoin, sulfamethoxazole trimethoprim and ciprofloxacin, respectively.
