“…In our study, we report a colonization rate of 13.82% ( n =455). This colonization rate is relatively higher compared with a study of general population conducted previously in our department, which reported a colonization rate of 8.84% ( n =1 451) 18 . Prevalence of colonization in our study was 15.65% in women and 12.67% in men.…”

Background: Due to its incidence, clinical polymorphism and severity, urinary tract infection is an important problem in elderly. The objectives of the authors’ work were to establish the bacteriological profile of urinary tract infection and/or colonization in the elderly and then to study drug resistance of bacterial strains isolated. Materials and methods: This is a 36 months retrospective study from 22 March 2016 to 11 May 2019. The study included urinary specimens of persons aged 65 years or over, hospitalized or consulting at the authors’ hospital. Urines were processed according to the recommendations of the medical microbiology reference system and European Committee on Antimicrobial Susceptibility Testing. Results: The authors collected 6552 requests for cytobacteriological examination of urine. Most of the specimens was collected in the middle stream (n=5503; 84%). Cultures were sterile in 49.77% of cases. Positive in 50.22% of cases. Among positive samples we had 53.41% polymorphic cultures, 32.75% urinary tract infection, and 13.82% urinary tract colonization. Gender distribution showed a sex ratio at 0.62. Gram-negative bacilli, with Escherichia coli as the main species, dominated the isolated bacteria. Resistance rates of E. coli strains that we isolated were 70% for amoxicillin, 36.31% for amoxicillin-clavulanate and 25% for ciprofloxacin. A high resistance rate was seen for third generation cephalosporins. Least resistance recorded to nitrofurantoin. Conclusion: ITU in the elderly is diverse and significantly different from that of younger patients, through its high contamination rate, difficulty in acquiring clinical information, high rate of asymptomatic bacteriuria, and high proportion of multidrug resistant bacteria.
