Research Article: Prevalent Dominant Acinetobacter baumannii ST// Strains in Bloodstream Infections Have High Drug Resistance and Mortality

Date Published: 2023-04-24

Abstract:
Acinetobacter baumannii (AB) is one of the most common pathogens causing hospital-acquired infections, some of which can prove fatal. AB was the most common pathogen in bloodstream infections (BSIs) acquired in hospitals in a multicenter cohort study conducted across countries. According to data from the China Bacterial Resistance Monitoring Network (CHINET) from to , AB accounted for .% of all isolated strains. Carbapenem antibiotics are the main drugs for treating AB infections. However, due to the widespread use of these antibiotics, the resistance rate of AB to carbapenem antibiotics has increased rapidly. Globally, ~% of AB isolates are resistant to carbapenems, with a resistance rate almost four times higher than that of other Gram-negative pathogens. The mortality of patients infected with carbapenem -resistant AB (CRAB) can be as high as –%., Therefore, in , the World Health Organization classified CRAB as a class of pathogens that pose a serious threat to global health, that require continuous public health surveillance and prevention, and for which priority should be given to the research and development of new antimicrobial therapies.
