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

BMC 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

Genomics, 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

Electrochemistry 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 ...

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

Canadian 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 ...

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

PLoS 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

DNA vaccines for bacterial infections

Immunology & 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.
