Increasing Dorea Formicigenerans

Another low bacteria is dorea formicigenerans reported by Ian Lapkin et al 2017 paper [Index to all posts on Study].  This bacteria was formerly known as Eubacterium formicigenerans [2002].

  • Bacteria> Firmicutes> Clostridia> Clostridiales> Clostridiaceae> Dorea> Dorea formicigenerans
  • Conditions with low Dorea:
    • Parkinson’s Disease [2017]
    • Functional Abdominal Pain in Children With Autism Spectrum Disorder. [2016] But without pain, Dorea is increased [2017]
  • “An adequate bowel cleansing (Moviprep),…notably increased the levels of Proteobacteria, Fusobacteria and bacteria related to Dorea formicigenerans.” [2015]
  • “decreased after treatment only in the antibiotic (amoxicillin, tetracycline and metronidazole for 2 weeks)  group. Eubacterium rectale, Dorea formicigenerans,”

That’s it!  Moving up the tree to Dorea, we have:

  • “prebiotic (fructo-oligosaccharides (FOS) and inulin mixture)..revealed a lower abundance of Dorea” [2017]
  • “bacteria (arabinogalactan and inulin) belonging to Gemmiger, Dorea, Roseburia, Alistipes, Lactobacillus and Bifidobacterium genera were found to be highly abundant or stimulated by the prebiotics in the lean microbiota” [2016]
  • Alcohol …  significant reductions in genra Clostridium IV and XIVb (p<0.001), Dorea (p<0.01), [2017]
  • “animal-based diet caused a significant increase in the relative abundance of Bilophila, Odoribacter, Dorea and Ruminococcus (belonging to Lachnospiraceae) and a significant decrease in the level of Bifidobacterium after five days of intake.” [2016]
  • High Molecular Weight Barley β-Glucan .. decreased Dorea” [2016]
    • whole-grain barley and barley malt, decreases” [2015]
  • Oral Iron …was associated with decreased abundances of operational taxonomic units assigned to the species Faecalibacterium prausnitzii, Ruminococcus bromii, Dorea sp.” [2017]  – IV Iron should be the preferred treatment in CFS
  • L-glutamine .. had statistically significant reduction. [2015]
  • L. rhamnosus hsryfm 1301.. positive correlation was observed between Ruminococcus spp. and serum triglycerides, Dorea spp. ” [2014]

Bottom Line

Above we see a lot of items to avoid. In terms of items to take, we have just a few

  • Inulin or arabinogalactan and inulin are beneficial
  • Lactobacillus rhamnosus
  • If you  are low in Iron, stop taking Oral Supplements and switch to IV Iron.
