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.

Prolonged carriage of OXA-244-carbapenemase-producing Escherichia coli complicates epidemiological investigations

International Journal of Medical Microbiology
The rapid increase of OXA-244-producing Escherichia coli, predominantly driven by genetically clustered isolates of sequence type (ST)38, has been observed in at least nine European countries, including Germany. However, the reasons for the spread of OXA-

In Vitro Activities of Colistin and Sitafloxacin Combinations against Multidrug-, Carbapenem-, and Colistin-Resistant Acinetobacter baumannii Using the Broth Microdilution Checkerboard and Time-Kill Methods

Antibiotics, 2020
Drug-resistant Acinetobacter baumannii (A. baumannii) infections are a critical global problem, with limited treatment choices. This study aims to determine the in vitro activities of colistin–sitafloxacin combinations against multidrug-, carbapenem- and

The first report of the coproduction of CMY-16 and ArmA 16S rRNA methylases in carbapenemase-ESBL producing Escherichia coli isolates

European Journal of Biological Research, 2020
The main aim of this work was to assess the occurrence and to characterize AmpC genes and to investigate the co-existence of 16S rRNA methylases and carbapenemases genes among the ESBL producing Escherichia coli strains.

On the essentiality of lipopolysaccharide to Gram-negative bacteria [PDF]

Current Opinion in Microbiology, 2013
Lipopolysaccharide is a highly acylated saccharolipid located on the outer leaflet of the outer membrane of Gram-negative bacteria. Lipopolysaccharide is critical to maintaining the barrier function preventing the passive diffusion of hydrophobic solutes such as antibiotics and detergents into the cell.

Acquisition of siderophores in Gram-negative bacteria

Nature Reviews Molecular Cell Biology, 2003
The outer membrane of Gram-negative bacteria constitutes a permeability barrier that protects the cell from exterior hazards, but also complicates the uptake of nutrients. In the case of iron, the challenge is even greater, because of the scarcity of this indispensable element in the cell's surroundings.

High genetic relatedness between multidrug resistant bacteria before and after the 2022 invasion of Ukraine

Genome Medicine
Background The Russian invasion of Ukraine in 2022 has placed extraordinary pressure on hospitals there. One consequence of this has been the alarming increase in infections caused by multi-drug resistant organisms (MDROs), both within Ukraine and among ...

Solvent tolerance in Gram-negative bacteria

Current Opinion in Biotechnology, 2012
Bacteria have been found in all niches explored on Earth, their ubiquity derives from their enormous metabolic diversity and their capacity to adapt to changes in the environment. Some bacterial strains are able to thrive in the presence of high concentrations of toxic organic chemicals, such as aromatic compounds, aliphatic alcohols and solvents.

Stopping an outbreak of Pseudomonas aeruginosa ST111 by temporarily blocking the siphon to disinfect it before the transition to the wastewater drain

GMS Hygiene and Infection Control
Introduction: Resulting from an analysis of an outbreak of carbapenem-resistant Pseudomonas (P.) aeruginosa, the siphons of washbasins in patient rooms were identified as source of colonizations and/or infections.
