A reservoir of 'historical' antibiotic resistance genes in remote pristine Antarctic soils [PDF]

, 2018
Background: Soil bacteria naturally produce antibiotics as a competitive mechanism, with a concomitant evolution, and exchange by horizontal gene transfer, of a range of antibiotic resistance mechanisms.

N-acetylhistidine, a novel osmolyte in the lens of Atlantic salmon (Salmo salar L.) [PDF]

, 2010
Volume homeostasis is essential for the preservation of lens transparency and this is of particular significance to anadromous fish species where migration from freshwater to seawater presents severe osmotic challenges. In Atlantic salmon (Salmo salar L.)

Insight into the AcrAB-TolC Complex Assembly Process Learned from Competition Studies

Antibiotics, 2021
The RND family efflux pump AcrAB-TolC in E. coli and its homologs in other Gram-negative bacteria are major players in conferring multidrug resistance to the cells.

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

, 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.

Indole contributes to tetracycline resistance via the outer membrane protein OmpN in Vibrio splendidus [PDF]

, 2020
As an interspecies and interkingdom signaling molecule, indole has recently received attention for its diverse effects on the physiology of both bacteria and hosts. In this study, indole increased the tetracycline resistance of Vibrio splendidus.

Isotope (¹⁴C and ¹³C) analysis of deep peat CO₂ using a passive sampling technique [PDF]

, 2009
We developed and tested a new method to collect CO₂ from the surface to deep layers of a peatland for radiocarbon analysis. The method comprises two components: i) a probe equipped with a hydrophobic filter that allows entry of ...

Overexpression of efflux pump genes is one of the mechanisms causing drug resistance in Mycobacterium tuberculosis

Microbiology Spectrum
Currently, drug resistance is a formidable obstacle to tuberculosisprevention globally. A deep understanding of the drug-resistance mechanism of Mycobacterium tuberculosis is helpful to deal with this problem.

Efflux Pump Activity and Mutations Driving Multidrug Resistance in Acinetobacter baumannii at a Tertiary Hospital in Pretoria, South Africa

International Journal of Microbiology, 2021
Acinetobacter baumannii (A. baumannii) has developed several resistance mechanisms. The bacteria have been reported as origin of multiple outbreaks. This study aims to investigate the use of efflux pumps and quinolone resistance-associated genotypic ...
