Abstract

---

One of the most common hospital-acquired infections (HAIs) is catheter-associated urinary tract infection (CAUTI). Proteus species (spp) are the primary infectious agent in patients with long-term indwelling urinary catheters. We aim to study some virulence factors of Proteus spp isolated from CAUTIs; three types of motility: swarming (SW), swimming (SM) and twitching (TW), urease production, biofilm formation and swarming over three different materials of urinary catheters (latex, silicon and silicon coated latex), also, Proteus isolates were tested for their sensitivity to different classes of antibiotics by disc diffusion method. This study was carried on 110 urine samples from CAUTI cases. Proteus isolates were (10/110 isolates, 12.5%). All of them were urease producers, strong biofilm former and had the ability to twitch, swim and swarm all over the plates except one strain. Four strains could bridge over latex catheters while two strains could bridge silicon catheters and silicon coated latex catheters. Seven strains were multidrug resistant (MDR) and two strains were extremely drug resistant (XDR) while only one strain was sensitive, so Proteus isolates from CAUTI are very virulent, so insert urinary catheter only if indicated and if you suspect long duration, use silicon better than latex.

Keywords: CAUTIs, Proteus, virulence factors, Catheter, Urinary tract infection.
