Résumé
Antimicrobial resistance of urinary tract pathogens has increased worldwide. Empiric treatment of community-acquired urinary tract infection [CA-UTI] is determined by antimicrobial resistance patterns of uropathogens in a population of specific geographical location. This study was conducted to determine the prevalence of CA-UTI in rural Odisha, India, and the effect of gender and age on its prevalence as well as etiologic agents and the resistance profile of the bacterial isolates. Consecutive clean-catch mid-stream urine samples were collected from 1670 adult patients. The urine samples were processed and microbial isolates were identified by conventional methods. Antimicrobial susceptibility testing was performed on all bacterial isolates by Kirby Bauer's disc diffusion method. The prevalence of UTI was significantly higher in females compared with males [females 45.2%, males 18.4%, OR = 2.041, 95% CI = 1.64-2.52, P /= 68 years] showed high prevalence of UTI. Escherichia coli [68.8%] was the most prevalent isolate followed by Enterococcus spp. [9.7%]. Amikacin and nitrofurantoin were the most active antimicrobial agents which showed low resistance rate of 5.8% and 9.8%, respectively. Our study revealed E. coli as the pre-dominant bacterial pathogen. Nitrofurantoin should be used as empirical therapy for uncomplicated CA-UTIs. In the Indian setting, routine urine cultures may be advisable, since treatment failure is likely to occur with commonly used antimicrobials. Therefore, development of regional surveillance programs is necessary for implementation of national CA-UTI guidelines
