Antimicrobial Resistance of Bacterial Uropathogens Before and During Coronavirus Pandemic

Abstract

Background: Define the most common bacterial isolates of urinary tract infections and the difference in the antibiotic resistance before and during the coronavirus pandemic.

Methods: The study included 213 patients with a diagnosis of urinary tract infection treated at the Clinic of infectious diseases in Mostar in a two-year period, 2019 and 2021. We analyzed the incidence of urinary infections, uropathogens and antibiotic resistance.

Main findings: We had total of 213 patients, more female patients, the average age was 66 and over, with the most clinical diagnosis of acute cystitis. The most common bacterial isolates were E. coli, K. pneumoniae and Entercoccus spp. We showed in 2019 decrease the incidence of E. coli and the increase in incidence of K. pneumoniae in 2021. Antibiogram results showed an increase in the antibiotic resistance in 2021 for all bacterial isolates except for K. pneumoniae.

Principal conclusion: The frequency of urinary tract infections was highest in older women with the most common diagnosis of acute cystitis. The most common bacterial pathogen of urinary tract infections are E. coli, K. pneumoniae and Enterococcus spp. as the main cause of urinary tract infections and general an increase in the antibiotic resistance of uropathogens.
