Diversity of culturable moderately halophilic and halotolerant bacteria in a marsh and two salterns a protected ecosystem of Lower Loukkos (Morocco) [PDF]

, 2012
To study the biodiversity of halophilic bacteria in a protected wetland located in Loukkos (Northwest, Morocco), a total of 124 strains were recovered from sediment samples from a marsh and salterns.

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

The Current Burden of Carbapenemases: Review of Significant Properties and Dissemination among Gram-Negative Bacteria

Antibiotics, 2020
Carbapenemases are β-lactamases belonging to different Ambler classes (A, B, D) and can be encoded by both chromosomal and plasmid-mediated genes.

Human platelet activation by Escherichia coli: roles for FcγRIIA and integrin αIIbβ3 [PDF]

, 2016
Gram-negative Escherichia coli cause diseases such as sepsis and hemolytic uremic syndrome in which thrombotic disorders can be found. Direct platelet–bacterium interactions might contribute to some of these conditions; however, mechanisms of human ...

Epidemiology and Diagnostics of Carbapenem Resistance in Gram-negative Bacteria

Clinical Infectious Diseases, 2019
Carbapenem resistance in gram-negative bacteria has caused a global epidemic that continues to grow. Although carbapenemase-producing Enterobacteriaceae have received the most attention because resistance was first reported in these pathogens in the ...

Destabilization of α-helical structure in solution improves bactericidal activity of antimicrobial peptides: Opposing effects on bacterial and viral targets [PDF]

, 2016
We have previously examined the mechanism of antimicrobial peptides on the outer membrane of vaccinia virus. Here we show that the formulation of peptides LL37 and magainin-2B amide in polysorbate 20 (Tween-20™) results in greater reductions in virus ...

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 ...

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.

Outer Membrane Lipid Secretion and the Innate Immune Response to Gram-Negative Bacteria

Infection and Immunity, 2020
The outer membrane (OM) of Gram-negative bacteria is an asymmetric lipid bilayer that consists of inner leaflet phospholipids and outer leaflet lipopolysaccharides (LPS). The asymmetric character and unique biochemistry of LPS molecules contribute to the

Multi-drug resistant Gram-negative bacteria: antibiotic-resistance and new treatment strategies [PDF]

, 2017
In this editorial, we treat the multi-drug-resistance of microorganisms such as Klebsiella pneumonia (Kp) and Acinetobacter baumanii and the issues concerning the management of these infections.
