«Checkerboard Array» as a Test for Evaluation of Decrease in Gram-Negative Bacteria Resistance to Carbapenems in the Presence of Bisphosphonate [PDF]

Клиническая микробиология и антимикробная химиотерапия, 2015
One of the main mechanisms of resistance of Gramnegative microorganisms to antibiotics is enzymatic hydrolysis by beta-lactamases (for example, metallobeta-lactamases).

Study of biofilm formation and antibiotic resistance pattern of gram-negative Bacilli among the clinical isolates at BPKIHS, Dharan

BMC Research Notes, 2019
Objectives Gram-negative bacilli are the common causative agents for community-acquired, nosocomial and opportunistic infections. The recent upsurge of biofilm, as well as beta-lactamases producing strains, have synergistically led to the extensive ...

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.

Antarctic soil microbiomes encode structurally conserved and phylogenetically diverse beta‐lactamases

iMetaOmics, EarlyView.
An integrative metagenomic framework combining sequence, structural, and functional inference reveals a phylogenetically diverse and structurally conserved repertoire of putative beta‐lactamases across Antarctic soil microbiomes, with predominance of class A and subclass B3 enzymes and limited but detectable associations with mobile genetic elements ...

Evaluation of Ceftriaxone as a Monotherapy and Amoxicillin With Clavulanic Acid as Combination Therapy in Surgical Prophylaxis

iNew Medicine, EarlyView.
ABSTRACT Surgical antibiotic prophylaxis (SAP) is crucial in preventing postoperative surgical site infections (SSIs), especially in clean and clean‐contaminated surgeries. It was a prospective comparative observational study that compared the effectiveness and safety of single‐dose ceftriaxone monotherapy with amoxicillin–clavulanic acid as a ...

Massive culture-based approach for the screening of AmpC, ESBL, and carbapenemase producers from rectal swabs

Microbiology Spectrum
Gram-negative bacilli-producing beta-lactamases are major causes of difficult-to-treat infections, especially the AmpC, extended-spectrum beta-lactamases (ESBL), and carbapenemase types. Their spread within and outside hospital settings demands effective

Detecting Antibiotic Resistance in Strains of Selected Gram‐Negative Bacterial Species Using Raman Spectroscopy

Journal of Raman Spectroscopy, EarlyView.
Raman spectroscopy successfully identified antibiotic‐resistant Gram‐negative strains. Resistant strains of four bacterial species were discriminated from sensitive ones with 99.1% accuracy using PLS regression. The method allows for rapid, label‐free detection of antibiotic resistance.
