Investigation of Citrobacter freundii clinical isolates in a Chinese hospital during 2020–2022 revealed genomic characterization of an extremely drug-resistant C. freundii ST257 clinical strain GMU8049 co-carrying blaNDM-1 and a novel blaCMY variant

ABSTRACT The emergence of multidrug-resistant Citrobacter freundii poses a significant threat to public health. C. freundii isolates were collected from clinical patients in a Chinese hospital during 2020–2022. An unusual strain, GMU8049, was not susceptible to any of the antibiotics tested, includi...
