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 ...

Regulation of innate and adaptive immune responses by Gram-positive and Gram-negative bacteria [PDF]

, 2009
Bacteria are classified as Gram-positive or Gram-negative, depending on their cell wall structure. The role of the bacterial cell wall in immune regulation is the focus of the current work.

Quorum-sensing in Gram-negative bacteria [PDF]

FEMS Microbiology Reviews, 2001
It has become increasingly and widely recognised that bacteria do not exist as solitary cells, but are colonial organisms that exploit elaborate systems of intercellular communication to facilitate their adaptation to changing environmental conditions.

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

Oligonucleotide recombination in Gram-negative bacteria [PDF]

Molecular Microbiology, 2010
This report describes several key aspects of a novel form of RecA-independent homologous recombination. We found that synthetic single-stranded DNA oligonucleotides (oligos) introduced into bacteria by transformation can site-specifically recombine with bacterial chromosomes in the absence of any additional phage-encoded functions.

Performance of seven carbapenemase detection assays in Pseudomonas aeruginosa across different epidemiological settings: a multicenter cross-sectional study

Journal of Clinical Microbiology
The detection of carbapenemases in Pseudomonas aeruginosa remains challenging due to a great variety of other resistance mechanisms, and most laboratories, therefore, do not test for them.

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.

Approaches forPurifying Recombinant Proteins from Gram Negative Bacteria [PDF]

, 2019
The ideal vaccine can generate a strong immune reaction without adverse effects on the body. Thus, many vaccines are now created using recombinant technology to accomplish this goal. Purification of recombinant proteins produced in Gram negative bacteria
