Exposure of clinical MRSA heterogeneous strains to β-lactams redirects metabolism to optimize energy production through the TCA cycle. [PDF]
PLoS ONE, 2013 Methicillin-resistant Staphylococcus aureus (MRSA) has emerged as one of the most important pathogens both in health care and community-onset infections. The prerequisite for methicillin resistance is mecA, which encodes a β-lactam-insensitive penicillin

Broad-spectrum β-lactamases among Enterobacteriaceae of animal origin: molecular aspects, mobility and impact on public health [PDF]
, 2010 Broad-spectrum β-lactamase genes (coding for extended-spectrum β-lactamases (ESBLs) and AmpC β-lactamases) have been frequently demonstrated in the microbiota of food-producing animals. This may pose a human health hazard since these genes may be present

A Clinical Extensively-Drug Resistant (XDR) Escherichia coli and Role of Its β-Lactamase Genes
Frontiers in Microbiology, 2020 An extensively-drug resistant (XDR) Escherichia coli W60 was isolated from the urine sample of a patient. The genetic basis for its XDR phenotype was investigated, particularly the basis for its resistance toward β-lactam/BLI (β-Lactamase Inhibitor ...

A degenerate PCR-based strategy as a means of identifying homologues of aminoglycoside and ß-lactam resistance genes in the gut microbiota [PDF]
, 2014 peer-reviewedBackground: The potential for the human gut microbiota to serve as a reservoir for antibiotic resistance genes has been the subject of recent discussion. However, this has yet to be investigated using a rapid PCR-based approach.

Antibiotic Resistance in Pseudomonas Aeruginosa is Associated with Decreased Fitness
Cellular Physiology and Biochemistry, 2013 The number of clinical specimens containing β-lactam-resistant Pseudomonas aeruginosa isolates is increasing. However, whether resistance is associated with reduced fitness is still uncertain in clinical Pseudomonas aeruginosa isolates. In this study, we
