Emergence of Aztreonam/Avibactam and Tigecycline-Resistant Pseudomonas putida group Co-producing blaIMP-1, blaAFM-4 and blaOXA-1041 With a Novel Sequence Type ST268 in Southwestern China

The emergence of carbapenem-resistant Pseudomonas putida (CRPP) has raised public awareness. This study investigated two strains from the Pseudomonas putida group that were resistant to carbapenem, tigecycline, and aztreonam-avibactam (ATM-AVI), with a focus on their microbial and genomic characteristics.
