Characterization of hydrogen peroxide-induced DNA release by Streptococcus sanguinis and Streptococcus gordonii.
Extracellular DNA (eDNA) is produced by several bacterial species and appears to contribute to biofilm development and cell-cell adhesion. We present data showing that the oral commensals Streptococcus sanguinis and Streptococcus gordonii release DNA in a process induced by pyruvate oxidase-dependent production of hydrogen peroxide (H(2)O(2)). Surprisingly, S. sanguinis and S. gordonii cell int...
متن کاملPneumococcus-Induced Serotonin Release from Human Platelets
present in normal human plasma and serum. We have identified this factor as immunoglobulin by: (a) removing it from plasma and serum with solid phase antiFab antibody; (b) demonstrating its absence from the serum of an individual with severe immunoglobulin deficiency; and, (c) showing its presence in IgG preparations isolated from normal individuals. Evidence suggesting that the release reactio...
متن کاملGenome of the opportunistic pathogen Streptococcus sanguinis.
The genome of Streptococcus sanguinis is a circular DNA molecule consisting of 2,388,435 bp and is 177 to 590 kb larger than the other 21 streptococcal genomes that have been sequenced. The G+C content of the S. sanguinis genome is 43.4%, which is considerably higher than the G+C contents of other streptococci. The genome encodes 2,274 predicted proteins, 61 tRNAs, and four rRNA operons. A 70-k...
متن کاملRole of Streptococcus sanguinis sortase A in bacterial colonization.
Streptococcus sanguinis, a normal inhabitant of the human oral cavity, has low cariogenicity, though colonization on tooth surfaces by this bacterium initiates aggregation by other oral bacteria and maturation of dental plaque. Additionally, S. sanguinis is frequently isolated from infective endocarditis patients. We investigated the functions of sortase A (SrtA), which cleaves LPXTG-containing...
متن کاملGenome-wide essential gene identification in Streptococcus sanguinis
A clear perception of gene essentiality in bacterial pathogens is pivotal for identifying drug targets to combat emergence of new pathogens and antibiotic-resistant bacteria, for synthetic biology, and for understanding the origins of life. We have constructed a comprehensive set of deletion mutants and systematically identified a clearly defined set of essential genes for Streptococcus sanguin...
