ceftazidime-avibactam offers a differentiated profile versus existing treatment options in serious Gram-negative infections through its coverage of a broad range of species of carbapenem-resistant Enterobacteriaceae (CRE) together with difficult to treat Pseudomonas aeruginosa combined with robust coverage of extended spectrum B-lactamase (ESBL)-expressing pathogens.
Phenotypic detection of carbapenem susceptible metallo B-lactamase producing Gram negative bacilli in the clinical laboratory.
These data confirm the presence of an extended spectrum b-lactamase (ESBL) producing IncHI2 plasmid in strain A54560 that is capable of con jugative transfer and suggest that the plasmid might have been acquired by residual index strain within the patient by transfer from an unknown donor bacterium.
