Streptococcus ⇒ Streptococcus oralis {10000859} Record Keys Parent:Streptococcus Definition:Streptococcus oralis Details Initialisation date:[ ] Meta Information Rank: Species Domain: Bacteria Zone:[ ] Enzyme:[ ] Function:[ ] Notes: [ ]Shared Reference Notes [1.1] [#Alzheimer’s disease] - The predominant bacterium of salivary microbiome and periodontal microbiome from AD patients was Streptococcus oralis and #Porphyromonas gingivalis, respectively. - P. gingivalis was associated with AD only in GCF. - the dominant species were different between early-onset AD and late-onset AD patients. - the predominant species were changed as the clinical severity of AD. [1.2] [#Candida albicans] - C. albicans colonization supports colonization with Streptococcus oralis in mice and leads to expansion of endogenous #Enterococcus faecalis [1.3] [#Streptococcus agalactiae, #Streptococcus anginosus, #Streptococcus gordonii, #Streptococcus parasanguinis] - S. anginosus, S. oralis subsp oralis, S. parasanguinis, S. gordonii, and S. agalactiae were associated with coronary #Atherosclerosis. - These species all belong to the viridans group streptococci (VGS), except for S. agalactiae (a β-hemolytic non-VGS). - VGS can enter the bloodstream through mucosal barrier injuries from daily dental care activities and dental procedures, and could also pass the gut barrier when injured. - VGS can invade human aortic endothelial cells and stimulate #Atherosclerosis-related proinflammatory cytokines [1.4] [#Lactobacillus acidophilus, #Lactobacillus jensenii, #Streptococcus gordonii, #Streptococcus mitis, #Streptococcus sanguinis] - Some species in the oral cavity involved in this process produce #Hydrogen peroxide (H2O2). Known peroxigenic oral bacteria include: Streptococcus oralis, S. mitis, S. sanguinis, S. gordonii, S. oligofermentans , #Lactobacillus fermentum, L. jensenii, L. acidophilus, L. minutus, and #Bifidobacterium adolescentis [#Streptococcus gordonii, #Streptococcus mitis, #Streptococcus salivarius, #Streptococcus sanguinis] [#Alcohol Consumption] - Several oral microbial species such as #Streptococci S. gordonii, S. mitis, S. oralis, S. salivarius, S. sanguinis, and #Candida yeasts possess the enzyme alcohol dehydrogenase (ADH), which metabolizes alcohol to #Acetaldehyde, which is indisputably carcinogenic. [#Streptococcus constellatus, #Streptococcus mitis, #Streptococcus salivarius, #Streptococcus sanguis] - oral #Streptococci (#Streptococcus intermedius, S. constellatus, S. oralis, S. mitis, S. sanguis, S. salivarius) were the most common isolates from cervical lymph nodes in patients with #Oral cancer. - Among the anaerobic bacteria, #Peptostreptococcus spp. dominated [1.5] [#Natural oral microbiomes] [#Streptococcus mutans] - #sIgA binds to oral bacteria, such as #Streptococcus mitis, Streptococcus oralis, and S. mutans, which have epitopes recognized by #sIgA, selectively recruiting these specific bacteria to the mucus layer on the mucosal surfaces of the oral cavity. [1.6] [#Candida albicans, #Fusobacterium nucleatum] - The ability of C. albicans to form alliances with F. nucleatum, circumventing host defenses, and its interaction with #Streptococcus mutans, or S. oralis to exacerbate oral candidiasis or dental #CariesReferences Notes[ ]
