Đặc điểm vi sinh vật và mức độ nhạy cảm kháng sinh của nhiễm khuẩn tiết niệu liên quan ống thông bàng quang

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.
