Molecular characterization of the whole genome in clinical multidrug-resistant strains of Klebsiella pneumoniae

Journal of Infection in Developing Countries, 2023
Introduction: Antimicrobial resistance (AMR) is a major public health concern. The spread of AMR-encoding genes between enterobacteria, especially in Klebsiella pneumoniae strains, lead to failure in the treatment of most individuals.

Ampicillinase C Beta-lactamase Producers among Isolates of Enterobacteriaceae in a Tertiary Care Centre: A Descriptive Cross-sectional Study

Journal of Nepal Medical Association, 2022
Introduction: Ampicillinase C beta-lactamase-producing organisms are often resistant to multiple antimicrobial agents, and therapeutic options against these pathogens are limited. Limited information is available regarding Ampicillinase C beta-lactamase

Presence of different beta-lactamase classes among clinical isolates of Pseudomonas aeruginosa expressing AmpC beta-lactamase enzyme

Journal of Infection in Developing Countries, 2010
Introduction: Infections caused by Pseudomonas aeruginosa are difficult to treat as the majority of isolates exhibit varying degrees of beta-lactamase mediated resistance to most of the beta-lactam antibiotics.

Escape mutations circumvent a tradeoff between resistance to a beta-lactam and resistance to a beta-lactamase inhibitor

Nature Communications, 2020
Beta-lactam antibiotics and beta-lactamase inhibitors compete for the same binding site on beta-lactamases; thus, mutations that increase beta-lactamase activity likely increase also susceptibility to the inhibitor. Here, Russ et al.
