Introduction:
Urinary tract infection (UTI) is one of the most common bacterial human infections encountered in medical practice in developing countries. More than ۱۰۵ colonies of an organism per milliliter of urine samples shows the symptom of UTI. The major UTIs caused by strains of Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa and Proteus. Antibiotics play an important role in treating infections. Area-specific studies aimed to gain knowledge about the type of pathogens responsible for UTIs and their resistance patterns may help the physician to choose the correct empirical treatment.Therefore, the aim of this study was to determine the distribution and antibiotic resistance patterns of bacterial strains isolated from hospitalized patients of ****from ۲۰۱۱ to ۲۰۱۶
Methods and materials:
This cross sectional study was conducted over a ۵-year period. All data available on all urine samples of hospitalized patients that was submitted to the ****laboratory for urine culture …show more content…

Of the total positive samples, ۶۸.۶% were female and ۳۱.۴% were male. The most common pathogens isolated were Escherichia coli (۵۷.۶%), Citrobacter (۱۴.۳%) and Enterobacter (۱۱.۷%). In Antibiotic susceptibility on all obtained data, most sensitivity was related to Amikacin (۴۸.۲%) and most resistance to Ampicillin (۳۲.۸%). in the case study E. coli and Enterobacter showed the highest percentage of resistance to ampicillin (۸۸%) and Nalixic Acid (۶۱%) and Citrobacter to Ampicillin (۷۱.۴%) . however, most isolates of E.Coli were susceptible to Nitrofurantoin (۷۶.۳%), Ceftizoxime (۶۵.۷%), Amicacin (۶۷.۲%) and Enterobacter to Gentamicin (۷۲.۴%), Imipenem (۷۱%), Ciprofloxacin (۶۷.۴%) and Citrobacter to Ciprofloxacin (۷۱.۵%) and Imipenem (۶۶.۷%). Most UTIs samples was observed among CCU hospitalized patients (۴۹.۶%) and then respectively surgery unit (۲۳.۷%), emergency unit (۱۳.۸%), Heart unit (۷.۵%) and ICU
