Plasmids of Psychrotolerant Polaromonas spp. Isolated From Arctic and Antarctic Glaciers – Diversity and Role in Adaptation to Polar Environments

open access: yesFrontiers in Microbiology, 2018
Cold-active bacteria of the genus Polaromonas (class Betaproteobacteria) are important components of glacial microbiomes. In this study, extrachromosomal replicons of 26 psychrotolerant Polaromonas strains, isolated from Arctic and Antarctic glaciers ...

How endo- is endo-?: surface sterilization of delicate samples: a Bryopsis (Bryopsidales, Chlorophyta) case study [PDF]

open access: yes, 2010
In the search for endosymbiotic bacteria, elimination of ectosymbionts is a key point of attention. Commonly, the surface of the host itself or the symbiotic structures are sterilized with aggressive substances such as chlorine or mercury derivatives ...

STRUCTURE AND IMMUNE ADJUVANT PROPERTIES OF CPG-D

open access: yesМедицинская иммунология, 2014
Bacterial DNA, along with other bacterial pathogen-associated molecular structures, may activate both innate and adaptive immune systems. This activity is associated with by nonmethylated CpG dinucleotides, which are present in the bDNA molecule, and it ...

Choice of DNA extraction method affects detection of bacterial taxa from retail chicken breast

open access: yesBMC Microbiology, 2022
Background Sequence-based methods for the detection of bacteria such as 16S rRNA amplicon sequencing and metagenomics can provide a comprehensive view of the bacterial microbiome of food.

High Sensitivity of Shotgun Metagenomic Sequencing in Colon Tissue Biopsy by Host DNA Depletion

open access: yesGenomics, Proteomics & Bioinformatics, 2023
The high host genetic background of tissue biopsies hinders the application of shotgun metagenomic sequencing in characterizing the tissue microbiota. We proposed an optimized method that removed host DNA from colon biopsies and examined the effect on ...

The antimicrobial polymer PHMB enters cells and selectively condenses bacterial chromosomes [PDF]

open access: yes, 2016
To combat infection and antimicrobial resistance, it is helpful to elucidate drug mechanism(s) of action. Here we examined how the widely used antimicrobial polyhexamethylene biguanide (PHMB) kills bacteria selectively over host cells.

A Toll for lupus [PDF]

open access: yes, 2005
Toll-like receptor (TLR)-9 recognizes CpG motifs in microbial DNA. TLR9 signalling stimulates innate antimicrobial immunity and modulates adaptive immune responses including autoimmunity against chromatin, e.g., in systemic lupus erythematosus (SLE ...

Inherent bacterial DNA contamination of extraction and sequencing reagents may affect interpretation of microbiota in low bacterial biomass samples

open access: yesGut Pathogens, 2016
BackgroundThe advent and use of highly sensitive molecular biology techniques to explore the microbiota and microbiome in environmental and tissue samples have detected the presence of contaminating microbial DNA within reagents.

Bacteria in the airways of patients with cystic fibrosis are genetically capable of producing VOCs in breath. [PDF]

open access: yes, 2016
Breath contains hundreds of volatile organic compounds (VOCs), the composition of which is altered in a wide variety of diseases. Bacteria are implicated in the formation of VOCs, but the biochemical mechanisms that lead to the formation of breath VOCs ...

Bacteria-human somatic cell lateral gene transfer is enriched in cancer samples. [PDF]

open access: yesPLoS Computational Biology, 2013
There are 10× more bacterial cells in our bodies from the microbiome than human cells. Viral DNA is known to integrate in the human genome, but the integration of bacterial DNA has not been described. Using publicly available sequence data from the human
