Abstract

Background: Acinetobacter baumannii is currently being considered by the World Health Organization (WHO) as the first bacteria of interest in hospital control and treatment. Objectives: to determine the prevalence of infection and antibiotic resistance of Acinetobacter baumannii bacteria isolated from respiratory tract specimens at Can Tho City General Hospital, 2021. Materials and methods: a cross-sectional descriptive study analyzed over 318 samples from respiratory specimens of patient who was diagnosed with pneumonia at Can Tho City General Hospital in 2021. Results: 100/318 samples of Acinetobacter baumannii were isolated, accounting for 31.4%. Most of the bacteria Acinetobacter baumannii were resistant to 13 experimental antibiotics with rates ranging from 75% with Tobramycin to 100% with Cefazolin. Acinetobacter baumannii was only susceptible to a few antibiotics: colistin with the ratio 91/100 (91%), trimethoprim/sulfamethoxazole (50%) or tobramycin 22/100 (22%) and a very small percentage from 0 -11% Acinetobacter baumannii has intermediate resistance. Conclusions: The prevalence of infection with Acinetobacter baumannii was quite high (31.4%). Acinetobacter baumannii was also determined to be highly resistant (over 75%) to 13/15 experimental antibiotics.
