Abstract

Urinary tract infections are among the most common diseases in our population that most often affects females, being symptomatic or asymptomatic, which, if not treated in time there are complications in the future.

The study was descriptive, using simple random selection and whose purpose was to determine urinary tract infection, identify the causative agent and antimicrobial susceptibility in women aged 18-45 years in the city of Cuenca. We analyzed 400 urine samples by elemental and microscopic examination of urine (EMO) useful in the search for bacteria and cellular structures (pus cells, leukocytes, etc.) that guided us to an infection. To perform the urine culture and sensitivity was considered from two crosses of bacteria in the EMO, this method was based on planting, inoculation, interpretation, reading, isolation and reseeding of the microorganism; all these procedures were performed using bio-security measures and making the appropriate quality controls.

Of the 400 samples tested, 41 were positive for ITU, representing 10%, against 90% of negative samples. The group with the highest prevalence of infection was 18-21 years.

The most common pathogen was Escherichia Coli with 88%, followed by 10% Staphylococcus and Proteus 2%. Meropenem was found that the antibiotic was the most sensitive, followed by Nitrofurantoin and Fosfomycin.

Amoxicillin / Clavulanic Acid, Cefadroxil and Gentamicin were Trimethoprim Sulfa antibiotics showed resistance compared with other antimicrobial.
