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 ...

In situ electrochemical investigation of the interaction between bacteria Xylella fastidiosa DNA and copper(II) using DNA-electrochemical biosensors

open access: yesElectrochemistry Communications, 2021
New emerging bacterial plant diseases are spreading fast in different geographical regions, and effective safety measures have not been found. Xylella fastidiosa (Xf) is a Gram-negative bacterial plant pathogen classified as a priority quarantine pest ...

DNA vaccines for bacterial infections

open access: yesImmunology & Cell Biology, 1997
DNA vaccines are an exciting development in vaccine technology which may have a special role in preventing viral infections and as ‘theracines’ for cancer. Their use in preventing bacterial infections has, by comparison, been less well documented.

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

Potential Capsule Switching from Serogroup Y to B: The Characterization of Three such Neisseria meningitidis Isolates Causing Invasive Meningococcal Disease in Canada

open access: yesCanadian Journal of Infectious Diseases and Medical Microbiology, 2005
Three group B Neisseria meningitidis isolates, recovered from meningococcal disease cases in Canada and typed as B:2c:P1.5, were characterized. Multilocus sequence typing showed that all three isolates were related because of an identical sequence ...

Natural History of DNA-Dependent DNA Polymerases: Multiple Pathways to the Origins of DNA

open access: yesViruses, 2023
One of the major evolutionary transitions that led to DNA replacing RNA as the primary informational molecule in biological systems is still the subject of an intense debate in the scientific community.

Comparison of Bacterial DNA Profiles in Mid-Trimester Amniotic Fluid Samples From Preterm and Term Deliveries

open access: yesFrontiers in Microbiology, 2020
Infection and inflammation are well recognized causes of spontaneous preterm delivery (PTD) (<37 gestational weeks) and adverse infant outcomes. To date, there has been very little investigation into bacterial communities in amniotic fluid using next ...

An efficient strategy for broad-range detection of low abundance bacteria without DNA decontamination of PCR reagents. [PDF]

open access: yesPLoS ONE, 2011
BACKGROUND: Bacterial DNA contamination in PCR reagents has been a long standing problem that hampers the adoption of broad-range PCR in clinical and applied microbiology, particularly in detection of low abundance bacteria.

Bacterial Extracellular DNA Promotes β-Amyloid Aggregation

open access: yesMicroorganisms, 2021
Alzheimer’s disease is associated with prion-like aggregation of the amyloid β (Aβ) peptide and the subsequent accumulation of misfolded neurotoxic aggregates in the brain.
