Ceftazidime/avibactam resistance associated with L169P mutation in the omega loop of KPC-2

Journal of Antimicrobial Chemotherapy, 2019
Objectives Ceftazidime/avibactam resistance due to mutation in the omega loop of KPC-2 has been documented in vitro and in vivo. This study evaluated the mechanism of ceftazidime/avibactam resistance in a KPC-2-expressing Klebsiella pneumoniae isolated ...

Emergence of ceftazidime/avibactam resistance in KPC-3-producing Klebsiella pneumoniae in vivo.

Journal of Antimicrobial Chemotherapy, 2019
OBJECTIVES The β-lactam/β-lactamase inhibitor combination ceftazidime/avibactam is active against KPC-producing Enterobacterales. Herein, we present molecular and phenotypic characterization of ceftazidime/avibactam resistance in KPC-3-producing ...

Has Monopotassium Phthalocyanine, KPc, Been Synthesized?

Inorganic Chemistry, 2007
A recent publication described the synthesis and characterization of monopotassium phthalocyanine, KPc. A reevaluation of the original EPR, magnetic susceptibility, and X-ray diffraction data, along with a comparison to the powder diffraction pattern of an authentic sample of Na2Pc, indicates that the material was actually Na2Pc.
