Abstract

Objective: To study the characteristics of microorganisms and the antibiotic sensitivity levels of urinary tract infections associated with indwelling catheters. Subjects and Methods: 14 patients diagnosed with catheter-associated urinary tract infections, treated in the Emergency and Intensive Care Department of Vietnam National Cancer Hospital from March 2022 to November 2022. Results: 16 bacteria/fungi were isolated. E.coli was the most frequently encountered (31.5%), followed by Pseudomonas aeruginosa (12.5%), Klebsiella pneumoniae (12.5%), and Candida fungi (12.5%). Candida fungi were 100% sensitive to the tested antifungal medications. E.coli remained 100% sensitive to imipenem, meropenem, and amikacin. Klebsiella pneumoniae was 100% sensitive to fosfomycin and 50% sensitive to other groups of antibiotics. The Gram-positive bacteria Enterococcus spp. were 100% sensitive to vancomycin and linezolid. Conclusion: The microorganisms causing catheter-associated urinary tract infections are primarily Gram-negative bacteria, with a smaller proportion of Gram-positive bacteria and fungi. These bacteria remain relatively sensitive to antibiotics.
