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 waves and water [PDF]

open access: yes, 2010
Some bacterial and viral DNA sequences have been found to induce low frequency electromagnetic waves in high aqueous dilutions. This phenomenon appears to be triggered by the ambient electromagnetic background of very low frequency.

Bacterial DNA Extraction Using Individual Enzymes and Phenol/Chloroform Separation†

open access: yesJournal of Microbiology & Biology Education, 2017
Marmur (4) developed one of the first detailed comprehensive methods for purifying bacterial DNA. This procedure is now outdated, and can be difficult to follow for those with limited experience in molecular biology.

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 ...

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.

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.
