Microwave assisted antibacterial action of Garcinia nanoparticles on Gram-negative bacteria
Nature Communications, 2022 Owing to the existence of the outer membrane barrier, most antibacterial agents cannot penetrate Gram-negative bacteria and are ineffective. Here, we report a general method for narrow-spectrum antibacterial Garcinia nanoparticles that can only be ...

Outer Membrane Vesicles of Gram-Negative Bacteria: An Outlook on Biogenesis
Frontiers in Microbiology, 2021 Outer membrane vesicles (OMVs) from Gram-negative bacteria were first described more than 50 years ago. However, the molecular mechanisms involved in biogenesis began to be studied only in the last few decades.

Resistance of Gram-Negative Bacteria to Current Antibacterial Agents and Approaches to Resolve It
Molecules, 2020 Antimicrobial resistance represents an enormous global health crisis and one of the most serious threats humans face today. Some bacterial strains have acquired resistance to nearly all antibiotics.

Antimicrobial Resistance and Infection Control, 2022 Background Since May 2016, infection and colonisation with carbapenem non-susceptible Acinetobacter spp. (CRA) and Enterobacterales (CRE) have to be notified to health authorities in Germany. The aim of our study was to assess the epidemiology of CRA and

Environmental microbial communications in gram-positive and gram-negative bacteria [PDF]
Global Journal of Environmental Science and Management, 2023 Microorganisms are present in nature and shape an enormous a half of our micro- and macro-environment. Quorum sensing is the process of intercellular conversation that enables microbes to perceive their surroundings and change their behaviour, allowing ...

Gene Transfer Potential of Outer Membrane Vesicles of Gram-Negative Bacteria
International Journal of Molecular Sciences, 2021 The increasing spread of multidrug-resistant pathogenic bacteria is one of the major threats to public health worldwide. Bacteria can acquire antibiotic resistance and virulence genes through horizontal gene transfer (HGT).

Interactions between Avibactam and Ceftazidime-Hydrolyzing Class D β-Lactamases
Biomolecules, 2020 Class D β-lactamases exhibit very heterogeneous hydrolysis activity spectra against the various types of clinically useful β-lactams. Similarly, and according to the available data, their sensitivities to inactivation by avibactam can vary by a
