PREVALENCE AND ANTIBIOTIC RESISTANCE PATTERN OF GRAM POSITIVE UROPATHOGENIC BACTERIA ISOLATED FROM URINE SAMPLES IN BANDAR TORKAMAN, IRAN

Background and Aim: Urinary tract infection (UTI) is one of the most common bacterial infections in humans, so updated epidemiological data on antibiotic resistance pattern of agents will be a big help for physicians to prescribe the choice antibiotic. The aim of this study was to determine antibiotic resistance pattern of Gram positive uropathogenic isolated from urine samples referred to clinical laboratories of Bandar Torkaman, Iran.Methods:In this study from April to June 2017, midstream urine samples were collected from patients who had clinical manifestation of UTI. In positive samples uropathogenic bacteria were identified by biochemical tests and their antibiotic resistance pattern were determined by disk diffusion method against different antibiotics.Results:Out of 1754 urine samples, 89 samples were positive for urinary infection. The most commonly isolated were as follows: Staphylococcus epidermidis (30), Staphylococcus saprophyticus (6), Micococcus sp. (3), Group B Streptococcus (28), Non-hemolytic Streptococcus (10), Alpha-hemolytic Streptococcus (5) and Group D Streptococcus (7). Among the isolates, the highest resistance rates were observed for Ampicilin and Cotrimoxazole. All the isolates were sensitive to Vancomycin.Conclusion:The result of this study revealed that Staphylococcus epidermidis and Group B Streptococcus were the most common isolated bacteria from the urine samples. Moreover, according to more than half of the isolates were resistant to antibiotics commonly used in clinical practices, performing an accurate Antibiogram test before prescribing antibiotics is recommended and is an inevitable necessity.
