The study of infectious agents of the urinary tract infections in Durrës, Albania

Urinary tract infections (UTI) are characterized by the presence of infectious agents in the genital-urinary tract that cannot be explained by contamination. These agents have the potential to invade the tissues of the urinary tract and adjacent structures. Settings and Design: Prospective study was done in the Health Directory in Durrës. Methods and Material: The study included all the patients who were admitted or visited the outpatient departments in the Health Directory and had urinary tract infection confirmed by positive urine culture reports. Results: A total 3160 urine samples were analyzed for isolation and identification of bacterial isolates. Out of which 956 (30.25%) samples were found to have significant bacteriuria and remaining 2204 samples were found to have either non significant bacteriuria or very low bacterial count or sterile urine. In the present study, out of 223 isolated pathogens the most common isolate was Escherichia coli (25.89%), followed by Staphylococcus aureus (2.94%), Proteus vulgaris (1.04%) and Pseudomonas aeruginosa (0.38 %). Age group most affected by Escherichia coli is 61-75 years (38.8%). Conclusions: Women are more susceptible to urinary tract infections, especially against Escherichia coli, resulting positive in 52.4% of cases; while Proteus vulgaris have a female percentage of 57.7%. This percentage increased slightly among women infected with Staphylococcus saprophyticus in 58% and low in 61.5% infected with Pseudomonas aeruginosa.
