Evolution of Antibiotic Resistance in and from Urine Cultures.

Objective: Determine the evolution of antibiotic resistance of symptomatic bacteriuria caused by and in Granada.

Material And Method: A descriptive retrospective study was carried out, including antibiograms of urine cultures in which microorganisms identified as and , were isolated in the Microbiology laboratory of the Hospital Universitario Virgen de las Nieves (Granada, Spain) between January 2016 and June 2021.

Results: was the most frequent isolate (10,048) and its resistance to ampicillin (59.45%) and ticarcillin (59.59%), and the increase to cefepime (15.07%) and amoxicillin-clavulanic acid (17.67%) is noteworthy. (2222) is notable for resistance to Fosfomycin (27.91%) and an increase to ciprofloxacin (37.79%) and amoxicillin-clavulanic acid (36.63%). Resistance is generally higher in hospitalized patients, males, and adults.

Conclusions: Antibiotic resistance to the studied is on the rise, requiring empirical treatment targeted to the population area.
