Streptococcus ⇒ Streptococcus mitis {10000317}

Shared Reference Notes

• [1.1] [#Crohn’s disease] [#Dorea longicatena, #Ruminococcus lactaris] 
  - ileocolonic resection (ICR) in CD patients > amples collected at time of surgery were enriched in #Proteobacteria and harbored high levels of unusual, bacteria such as Streptococcus mitis, #Undibacterium oligocarboniphilum, #Sphingomonas melonis and #Gemella haemolysans - 6 months after surgery samples had elevated proportions of anaerobic bacteria belonging to #Lachnospiraceae (#Clostridium nexile, #Blautia wexlereae, #Dorea longicatena). - Remission was characterized by increased levels of bacteria belonging to #Bacteroides, #Dorea, #Ruminococcus and #Dialister genera, whereas recurrence was associated with increased levels of #Gemmiger formicilis, #Enterococcus durans and #Ruminococcus lactaris.
• [1.2] [#Lactobacillus acidophilus, #Lactobacillus jensenii, #Streptococcus gordonii, #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 oralis, #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 oralis, #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
• [#Oral squamous cell carcinoma] - The levels of three species (#Capnocytophaga gingivalis, #Prevotella melaninogenica, and Streptococcus mitis) were elevated in the saliva of patients suffering from OSCC.
• [#Pancreatic Cancer] - In pancreatic cancers, in addition to #Fusobacterium nucleatum and #Porphyromonas gingivalis, strains of #Aggregatibacter actinomycetemcomitans, #Neisseria elongata, and Streptococcus mitis have been described.
• [1.3] [#Crohn’s disease] [#Colectomy] 
  - in CD patients > Six months after surgery, ten patients developed recurrence of CD lesions. Samples collected at time of surgery were enriched in #Proteobacteria and harbored high levels of unusual, bacteria such as Streptococcus mitis, #Undibacterium oligocarboniphilum, #Sphingomonas melonis and #Gemella haemolysans, while 6 months after surgery samples had elevated proportions of anaerobic bacteria belonging to #Lachnospiraceae (#Clostridium nexile, #Blautia wexlereae, #Dorea longicatena). Remission was characterized by increased levels of bacteria belonging to Bacteroides, Dorea, Ruminococcus and Dialister genera, whereas recurrence was associated with increased levels of #Gemmiger formicilis, #Enterococcus durans and #Ruminococcus lactaris.
• [1.4] [#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.
• [1.5] [#Idiopathic Pulmonary Fibrosis] 
  - IPF > The buccal proportion of #Streptococcus correlated positively with FVC. - IPF > Greater microbial diversity was associated with an increased risk of death while a greater proportion of #Streptococcus was associated with a reduced risk of death. - IPF > The #Streptococcus genus was mainly comprised of #Streptococcus mitis species. - IPF > The oral commensal #Streptococcus mitis spp associates with preserved lung function and improved survival.
