The porin and the permeating antibiotic: A selective diffusion barrier in gram-negative bacteria [PDF]

open access: yesNature Reviews Microbiology, 2008
Gram-negative bacteria are responsible for a large proportion of antibiotic resistant bacterial diseases. These bacteria have a complex cell envelope that comprises an outer membrane and an inner membrane that delimit the periplasm.

In Vitro Activity of Cefiderocol against Clinical Gram-Negative Isolates Originating from Germany in 2016/17

open access: yesAntibiotics, 2023
Antimicrobial resistance poses a global threat to public health. Of great concern are Acinetobacter baumannii, Pseudomonas aeruginosa and Enterobacterales with resistance to carbapenems or third-generation cephalosporins. The aim of the present study was

Environmental microbial communications in gram-positive and gram-negative bacteria [PDF]

open access: yesGlobal 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 ...

A recurrent and transesophageal echocardiography–associated outbreak of extended-spectrum β-lactamase–producing Enterobacter cloacae complex in cardiac surgery patients

open access: yesAntimicrobial Resistance and Infection Control, 2019
Background We report a recurrent outbreak of postoperative infections with extended-spectrum β-lactamase (ESBL)–producing E. cloacae complex in cardiac surgery patients, describe the outbreak investigation and highlight the infection control measures ...

IS26-Mediated Transfer of blaNDM–1 as the Main Route of Resistance Transmission During a Polyclonal, Multispecies Outbreak in a German Hospital

open access: yesFrontiers in Microbiology, 2019
One of the most demanding challenges in infection control is the worldwide dissemination of multidrug-resistant (MDR) bacteria in clinical settings. Especially the increasing prevalence of carbapenemase producing Gram-negative pathogens poses an urgent ...

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

open access: yes, 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.

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

open access: yes, 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 ...

Development of an NGS-Based Workflow for Improved Monitoring of Circulating Plasmids in Support of Risk Assessment of Antimicrobial Resistance Gene Dissemination

open access: yesAntibiotics, 2020
Antimicrobial resistance (AMR) is one of the most prominent public health threats. AMR genes localized on plasmids can be easily transferred between bacterial isolates by horizontal gene transfer, thereby contributing to the spread of AMR.

SYNTHESIS, CHARACTERIZATION AND STUDY THE EFFECT OF (3,5-DIMETHYL-1H-PYRAZOL-4- YL) MERCURY (II) CHLORIDE ON GROWTH INHIBITION OF SOME BACTERIA ,YEAST AND SOME FUNGI (IN VITRO). [PDF]

open access: yesBasrah Journal of Veterinary Research, 2008
The reaction of 3,5-dimethyl-1H-pyrazole with mercury (II)acetate in absolute methanol gave (3,5-dimethyl-1H-pyrazol-4-yl) mercury(II) chloride (DMPMC), which characterized by microanalysis, 1H, and 13C-NMR and IR.
