Abstract

Background: Currently, the World Health Organization (WHO) ranks Acinetobacter baumannii as a priority bacteria in the number 1 group of bacteria that are difficult to control and treat related diseases.. Objectives: To determine the infection rate and antibiotic resistance rate of Acinetobacter baumannii isolated from patients with hospital-acquired pneumonia at Can Tho General Hospital in 2024-2025. Materials and methods: A cross-sectional descriptive study with analysis was conducted on 314 respiratory tract specimens of pneumonia patients at Can Tho General Hospital in 2024-2025. Results: 100/314 Acinetobacter baumannii samples were isolated, accounting for 31.4%. Most Acinetobacter baumannii bacteria were highly resistant to 13 experimental antibiotics with rates ranging from 75% to tobramycin to 100% to cefazolin. Acinetobacter baumannii bacteria were only sensitive to a few antibiotics: colistin with a rate of 9%), trimethoprim/sulfamethoxazole with a rate of 50% and a very small rate of 0-11% Acinetobacter baumannii with intermediate resistance. Conclusions: The rate of isolation of Acinetobacter baumannii bacteria was quite high (31.4%). Acinetobacter baumannii bacteria were also determined to be highly resistant (over 75%) to 13/15 experimental antibiotics.
