The Study of Common Bacterial Factors of Urinary Tract Infections and Determining their Antibiotic Resistance in Hospitalized and out patients Referred to the Vase’ee Hospital in Sabzevar in 2016

Urinary tract infection is the most common infectious diseases and increasing resistance to antimicrobial agents in bacteria is a major problem around the world in treatment of urinary infections. This study was conducted to identify causative agents of urinary tract infection and to determine their susceptibility to antibiotics in hospitalized and out patients referred to the Vase’ee Hospital in Sabzevar. This descriptive cross-sectional study was performed on 256 individuals hospitalized and out patients older than eighteen age in the Sabzevar Vase’ee hospital. Identification of bacteria was performed using biochemical tests and their susceptibility was determined by disk diffusion method. The data were analyzed using t-test, Chi-square and Fisher’s exact test with percentage error 5%. Of 256 patients, 59.7 % and 40.3% were female and male, respectively. The most frequently isolated pathogen were Escherichia coli (50.8%), Klebsiella (17.6%), Coagulase-Negative Staphylococci (15/62%), Enterobacter (7.8%). E. coli as most common pathogen of urinary tract infections showed the most resistance to ampicillin and the least resistance to Imipenem indicated. In total, regardless of the type of bacteria, the highest resistance was against amoxicillin and the lowest resistance was against Imipenem. Considering the frequency of urinary tract infections and in order to prevent serious complication, a survey of regional resistance pattern and timely treatment can control development of resistant bacteria.
