Đặc điểm phân loại lớp Ambler carbapenemase trên Acinetobacter spp. tại Bệnh viện Nhi Đồng 2

This study conducted a descriptive cross-sectional investigation on 93 strains of Acinetobacter spp. at Children's Hospital 2 from January 2019 to December 2020, with the goal of evaluating the rate of carbapenemase production and the distribution rate of Ambler carbapenemase classes in Acinetobacter spp. Results: Acinetobacter spp. bacteria that produce carbapenemase enzymes account for 82.8% (77/93), compared to 17.2% (16/93) of bacteria that do not. The Ambler D class of Acinetobacter spp. produces the highest carbapenemase, accounting for 39.8% (37/93), followed by the Ambler B class with 32.2% (30/93), the negative 17.2% (16/93), and lastly 10.8% (10/93). However, the Ambler class has yet to be found. Conclusions: There was no correlation between Acinetobacter spp. carbapenemase production and sex, age, specimen type, department, diagnosis, or number of days in the hospital across Ambler classes. The generation of carbapenemase by Ambler class Acinetobacter spp. differs significantly from the patient's condition upon discharge.
