Objective:

To determine the prevalence of uropathogens, sensitivity and antimicrobial resistance in urinary tract infections that go to the Private Basic Hospital "Provida" from January 1, 2014 to December 31, 2016.

Material and methods:

The results of 116 urine cultures in non-pregnant women of all ages from 2014 to 2016, which were treated at the Private Basic Hospital "Provida" of the city of Latacunga, in Ecuador, were analyzed. The data obtained was analyzed using descriptive statistics.

Results:

In the 116 samples, Escherichia coli (84.5%), Staphylococcus saprophyticus (8.6%) and Proteus spp. (6.9%) were isolated. E. coli showed sensitivity to ceftriaxone in 70%, followed by fosfomycin and gentamicin with 62 and 60%, respectively. The sensitivity found for quinolones was 40% and for sulbactam ampicillin reached a 37%. Proteus spp. showed sensitivity of 75% for gentamicin and 50% for quinolones and cefuroxime. S. saprophyticus had a sensitivity greater than 50% for gentamicin, sulbactam ampicillin, quinolones and nitrofurantoin. For E. coli the highest resistance recorded was found on ampicillin in 86.5%, followed by quinolones with a resistance greater than 50%. Ampicillin associated with inhibitor of beta-lactamase, fosfomycin, cephalosporins, nitrofurantoin and aminoglycosides showed a resistance below 25%.

Conclusion:

The most prevalent pathogen in urinary tract infections (UTI) is E. coli (84.7%), a percentage that matches what has been reported in national and world literature. The antimicrobials for this uropathogen with the highest resistance were ampicillin (86%), ciprofloxacin (55%) and norfloxacin (53%). This should be taken into account when administering an empiric therapy, even though this data should be corroborated with the susceptibility information depending on the context.
