Until today, one of the leading predominant infections is Urinary tract infection (UTI). It exerts a huge burden on health systems worldwide each year. Treating UTIs empirically with antimicrobials improves morbidity rates. This study aims to assess the prevalence of UTI-associated bacteria in adult patients and to determine their antibiotic susceptibility profile. A retrospective study was conducted for adult outpatients who visited Al-Diwaniya tertiary hospitals from January 2020 till February 2022 to review their medical and lab records in addition to sociodemographic data. A total of 256 patients’ records were included of which 204 (79.7%) belong to females and 52 (20.3%) were males with an average age of 39.22±17.10 years. The predominant organisms’ isolates were Staphylococcus spp. found in 100 records (39.1%), Escherichia coli (E. coli) demonstrated in 90 records (35.2%), and Klebsiella spp. (K. spp.) revealed in 23 records (9%). Staphylococcus spp. (Staph. spp.) showed high resistance to ampicillin (92.9%) followed by ceftazidime (87.5%), and were highly sensitive to vancomycin. The higher resistance profile of E. coli was to ampicillin (97.9%) and ceftriaxone (81.3%) while was highly susceptible to meropenem (97.9%) and amikacin (97.6%). Additionally, Klebsiella spp. was highly susceptible to nitrofurantoin (78.6%), while was completely resistant to ampicillin. This study presents Staphylococcus spp. as the most prevalent gram-positive uropathogen and E. coli as the most prevalent gram-negative bacteria with a multidrug resistance profile to commonly used antimicrobials which is an alarming situation to implement an immediate effective stewardship program.
