PREVALENCE OF URINARY TRACT INFECTIONS AND ITS CAUSATIVE AGENTS IN IMAM REZA HOSPITAL, BOJNURD, IN 1396

Background and Aim:bacterial infections are the most common infectious diseases in the urinary system and are able to engage the upper and lower urinary tract. Given the importance of urinary tract infections in this study the prevalence of and factors involved in urinary tract infection in Imam Reza Hospital were evaluated.Methods:Culture of urine samples received at the laboratory of Imam Reza Hospital was performed to determine the bacterial species. Isolates were identified using conventional biochemical tests.Results:In 1396 a total of 1754 urine culture were performed, of which between 193 (11%) were positive. Of the positive cases 79.8% were Escherichia coli, 4.1% were Staphylococcus aureus ,3.6% were Pseudomonas aeruginosa, 3.1% were Enterobacter aerogenes, 2.6% were Staphylococcus epidermidis, 2.6% were Streptococcus viridians, 2.1% were enterococci and also 2.1% were Proteus mirabilis.Conclusion:The results indicated that the overall rate of positive urine culture is lower than previous studies and E. coli is the leader agent. The relatively low percentage of cases with Proteus and Enterobacter in comparison with gram-positive bacteria, including Enterococci, Streptococci and Staphylococcus epidermidis shows the evolution of the common causes of urinary tract infections.
