L’origine des infections urinaires chez les patients hospitalisées à l’hôpital Dr Benzerdjeb (Ain Témouchent)

Abstract

Urinary tract infection attributed to the use of an indwelling urinary catheter is one of the most common infections contracted by patients in health care facilities. The purpose of our study is to identify bacteria that contaminate invasive material (urinary catheters) and bacteria that cause urinary tract infections. Out of a total of 7 samples taken at the Dr Benzerdjeb hospital from the urology, neurology and cardiovascular department, 23 strains were isolated and identified, of which 61% were enterobacteria and 39% staphylococci. The bacteriological profile was largely dominated by Enterobacter cloacae 43%, followed by Klebsiella pneumoniae 21%, Acinetobacter baumannii and Aeromonas hydrophila 14% and Proteus mirabilis 7%. Implanted urinary catheters provide extensive diffusion in an agar medium, indicating the impact of length of stay on biofilm formation and the onset of nosocomial urinary tract infections.
