Microbial community dynamics during composting of sewage sludge and straw studied through phospholipid and neutral lipid analysis [PDF]

, 2008
The composting process involves a succession of different communities of microorganisms that decompose the initial material, transforming it into a stable final product. In thiswork, the levels of phospholipid fatty acid (PLFA), neutral lipid fatty acid (

In host evolution of beta lactam resistance during active treatment for Pseudomonas aeruginosa bacteremia

Frontiers in Cellular and Infection Microbiology, 2023
Multidrug-resistant (MDR) Pseudomonas aeruginosa has been declared a serious threat by the United States Centers for Disease Control and Prevention. Here, we used whole genome sequencing (WGS) to investigate recurrent P. aeruginosa bloodstream infections

Molecular surveillance of carbapenemase-producing Pseudomonas aeruginosa at three medical centres in Cologne, Germany

Antimicrobial Resistance and Infection Control, 2019
Background Pseudomonas aeruginosa is a common pathogen causing hospital-acquired infections. Carbapenem resistance in P. aeruginosa is either mediated via a combination of efflux pumps, AmpC overexpression, and porin loss, or through an acquired ...

A single Proteus mirabilis lineage from human and animal sources: a hidden reservoir of OXA-23 or OXA-58 carbapenemases in Enterobacterales

Scientific Reports, 2020
In Enterobacterales, the most common carbapenemases are Ambler’s class A (KPC-like), class B (NDM-, VIM- or IMP-like) or class D (OXA-48-like) enzymes. This study describes the characterization of twenty-four OXA-23 or OXA-58 producing-Proteus mirabilis ...

Gram-Negative Bacteria’s Outer Membrane Vesicles

Infection & Chemotherapy, 2023
Outer membrane vesicles (OMVs) are spherical bilayered nanoparticles derived from the outer layer of Gram-negative bacteria. Bacteria communicate with nearby bacteria, their environment, and the cells of their host by secreting OMVs, which are essential for their survival.

Extended-spectrum ß-lactamases in gram negative bacteria

Journal of Global Infectious Diseases, 2010
Extended-spectrum ß-lactamases (ESBLs) are a group of plasmid-mediated, diverse, complex and rapidly evolving enzymes that are posing a major therapeutic challenge today in the treatment of hospitalized and community-based patients.

Five-year period evaluation of isolated agents and their resistance profiles in intensive care unit patients with malignancy

Journal of Infection in Developing Countries, 2020
Introduction: Patients treated in the intensive care unit (ICU) are usually patients who deteriorated health condition and could have longer hospital stay compared to other patients. Hospital infections are more common in ICU patients.

Trapped lipopolysaccharide and LptD intermediates reveal lipopolysaccharide translocation steps across the Escherichia coli outer membrane [PDF]

, 2015
Lipopolysaccharide (LPS) is a main component of the outer membrane of Gram-negative bacteria, which is essential for the vitality of most Gram-negative bacteria and plays a critical role for drug resistance.

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
