Evaluation Du Risque D’infections Urinaires Sur Sondes : Isolement Des Souches Uropathogènes Et Sensibilité À La Canneberge

Résumé: Faced with issues related to the massive use of antibiotics, which over time leads to an increase in bacterial resistance and side effects, a nutritional and natural approach based on cranberry can help reduce the use of antibiotics. The effectiveness of cranberry, known for its antibacterial properties, as a prophylactic alternative in the prevention of healthcare associated urinary tract infections is recognized. In this context, we undertook this study at the Beni Safe hospital in Ain Temouchent, which consists of isolating and identifying uropathogenic strains from urinary catheters, directly after their removal from patients, and on the other hand, testing their sensitivity to cranberry. Six bacterial strains were isolated, and the identification results showed that the implicated strains are: Escherichia coli, Pseudomonas aeruginosa, Enterococcus sp., and Staphylococcus aureus. The antibacterial activity of the cranberry extract was evaluated, revealing variable efficacy depending on the concentration. Notably, resistance was observed in E. coli at 20mg/mL, while the activity was more pronounced at lower concentrations. The results indicate that cranberry could play a significant role in the prevention of urinary tract infections, particularly in catheterized patients. The cranberry extract demonstrated notable antibacterial activity against E. coli, and moderate activity against Staphylococcus aureus. However, no activity was observed against Enterococcus sp. At concentrations above 20 mg/mL. This study highlights that cranberry can be used in the prevention of urinary tract infections.
