- Abstract
Introduction and Objectives: The most common human fungal pathogens are Candida species. Studies show that the incidence of urinary tract infections caused by Candida pathogens has increased in recent decades. The purpose of this research was to study the prevalence of Candida urinary tract infections among other causes of urinary tract infections as well as the prevalence percentage of different Candida species in causing this infection. Materials and Methods: In the current study, 500 specimens from patients with positive urine culture test were evaluated. Of these, 479 cases of bacterial infection, 19 cases of candidiasis and 2 cases of mixed infections caused by bacteria and fungi were diagnosed. Candida species were diagnosed based on germ tube test, the colony color on CHROMagar Candida medium, intracellular beta-glycosidase enzyme activity and carbohydrate assimilation pattern. Results: According to the results obtained, 33.3%, 28.6%, 14.3%, 9.2% and 9.5% of the isolates were C. albicans, C. glabrata, C. tropicalis, C. kruzei and C. kefir, respectively. Also, an isolate with a 4.7% incidence of C. dubliniensis was identified. The patients were also examined regarding to predisposing factors in this experiment. Interestingly, the presence of one or more predisposing factors was proved in all the patients of which diabetes was the most prevalent factor by 38% frequency. Concerning blood culture and HIV, all patients were negative. Fourteen patients had proteinuria and 13 patients had glycosuria. Conclusion: Based on obtained results, Candida albicans was the most prevalent species, and in general, urinary tract fungal infections were less prevalent than bacterial urinary infections.
