Which pathogen is known for forming biofilms on catheters in CAUTI?

• A. Enterococcus Faecalis
• B. Candida Albicans
• C. Pseudomonas Aeruginosa
• D. Escherichia Coli

Answer: (C)

Biofilms on catheter surfaces drive persistence and antibiotic resistance in catheter-associated infections. Pseudomonas aeruginosa is especially known for forming robust biofilms on urinary catheters, using extracellular matrix components and coordinated, quorum-sensing–regulated development to create a protective community that sticks to plastic and resists treatment. This capability is a hallmark of device-related infections, making it the best answer. While other organisms can form biofilms—Candida albicans can produce fungal biofilms on catheters, Enterococcus faecalis can form biofilms, and E. coli can as well—the strong, well-documented association of Pseudomonas with catheter biofilms is what sets it apart.
