Role of DNA in Bacterial Aggregation
Current Microbiology, 2008The role of DNA in bacterial aggregation was determined using various types of DNA and Escherichia coli, a good model for investigating the correlation between added polymer and bacterial aggregation and adsorption of polymer to bacterial surfaces. The results of the aggregation assay suggest that extracellular DNA indeed increased the aggregation ...

Arrest of Bacterial DNA Replication
Annual Review of Microbiology, 1992The chromosomes of both gram-positive and gram-negative bacteria contain sites that arrest the progression of DNA replication forks. These replication-arrest sites limit the end of the replication cycle to a particular region of the chromosome, called the terminus region.

Bacterial DNA in Clarkia fossils
Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 1991For the growing number of investigators who study ancient DNA, the most stimulating paper published during 1990 reported the determination of a chloroplast DNA sequence from a plant compression fossil found in a Miocene deposit at Clarkia, Idaho (Golenberg et al. 1990). During August 1990, S.P.

Dodecylamine in the isolation of bacterial DNA
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1971Abstract Lysis of enterobacteria by lysozyme and detergent was greatly accelerated by n-dodecylamine. Nicking of supercoiled DNA was not detected.

Bacterial Dna in Mixed Cholesterol Gallstones
American Journal of Gastroenterology, 1999Numerous investigators have proposed a role for bacteria in biliary lithogenesis. We hypothesized that bacterial DNA is present in gallstones, and that categorical differences exist between gallstone type and the frequency of bacterial sequences.Polymerase chain reaction (PCR) was used to amplify bacterial 16S rRNA and uidA (encoding Escherichia coli ...

The Antigenicity of Bacterial DNA
2002DNA is a complex macromolecule whose immunological properties vary with base sequence and backbone structure. Although now recognized as important for normal immunity, the antigenic and immunogenic properties of DNA were originally conceptualized entirely in the context of systemic lupus erythematosus (SLE).

DNA motifs that sculpt the bacterial chromosome
Nature Reviews Microbiology, 2010During the bacterial cell cycle, the processes of chromosome replication, DNA segregation, DNA repair and cell division are coordinated by precisely defined events. Tremendous progress has been made in recent years in identifying the mechanisms that underlie these processes.

Bacterial DNA Methylation and Methylomes
2016Formation of C5-methylcytosine, N4-methylcytosine, and N6-methyladenine in bacterial genomes is postreplicative and involves transfer of a methyl group from S-adenosyl-methionine to a base embedded in a specific DNA sequence context. Most bacterial DNA methyltransferases belong to restriction-modification systems; in addition, "solitary" or "orphan ...

Immobilization of plasmid DNA in bacterial ghosts
Journal of Controlled Release, 2005The development of novel delivery vehicles is crucial for the improvement of DNA vaccine efficiency. In this report, we describe a new platform technology, which is based on the immobilization of plasmid DNA in the cytoplasmic membrane of a bacterial carrier.

Mechanisms of immune stimulation by bacterial DNA [PDF]
Springer Seminars in Immunopathology, 2000 Bacterial DNA promotes powerful immune system activation because of its content of characteristic sequence motifs. These sequences induce cellular changes that promote inflammation and the generation of Thl responses. This activation involves internalization of DNA as well as the activation of NF-κB and stress kinases.
