For updated information see Microbiome Prescription

“Bifidobacterium and Veillonella are commensal anaerobes which reside in gastrointestinal tract and help deconjugate bile acids. ” [2010]

  •  “Microbial diversity and relative abundance of Streptococcus , Prevotella and Veillonella were inversely associated with airway inflammation in cystic fibrosis . ” [2017]
  • ” decreased abundance of genus Akkermansia but increased abundance of Veillonella was found in children with food allergy in comparison with healthy control children.” [2017]
  • “IBS microbiota is different from that of healthy individuals due to an unbalance in a number of commensal species, with an increase in relative abundance of lactobacilli, B. cereus and B. clausii, bifidobacteria, Clostridium cluster IX and E. rectale, and a decrease in abundance of Bacteroides/Prevotella group and Veillonella genus. ” [2012]
  • In the IBD group, Firmicutes, Proteobacteria, Verrucomicrobia, and Fusobacteria were significantly increased, whereas Bacteroidetes and Cyanobacteria were decreased. At genus level Escherichia, Faecalibacterium, Streptococcus, Sutterella and Veillonella were increased, ” [2017]
  • “Molecular techniques revealed Prevotella and Veillonella as potentially pathogenic anaerobic species with bronchiectasis ” [2017]


  • “alterations of the microbiota in the oral carriage microbiome along with bacterial overgrowth (Streptococcus) and decreases in distinct bacterial species (Neisseria, Veillonella) were observed with proton pump inhibitors (PPIs)” [2017]
  • “Veillonella. dispar DNA bands were markedly inhibited after washing with chlorhexidine mouthwash”. [2017]
  • “However, lipopolysaccharides increased with the reduction of 25(OH)D (p-trend <0.05). Prevotella was more abundant (log2FC 1.67, p<0.01), while Haemophilus and Veillonella were less abundant (log2FC -2.92 and -1.46, p<0.01, respectively) in the subset with the highest vitamin D intake” [2017]
  • “An Italian-style gluten-free diet caused increases in the abundance of Granulicatella, Porphyromonas and Neisseria and decreases in Clostridium, Prevotella and Veillonella,” [2015]



  • “Fecal calprotectin decreased rapidly in both groups. In the infants with dominant fecal gram negatives (Klebsiella, Proteus, and Veillonella), resolution of colic was associated with marked decreases in these organisms with Lactobacillus reuteri ” [2017]
  • ” After one month of Lactobacillus kefiri LKF01 DSM32079 (LKEF)  probiotic oral intake we observed a reduction of Bilophila, Butyricicomonas, Flavonifractor, Oscillibacter and Prevotella. Interestingly, after the end of probiotic administration Bacteroides, Barnesiella, Butyricicomonas, Clostridium, Haemophilus, Oscillibacter, Salmonella, Streptococcus, Subdoligranolum, and Veillonella were significantly reduced if compared to baseline samples.”
  • “there were greater proportions of Actinomyces and Streptococcus-like species and lower proportions of Veillonella parvula, Capnocytophaga sputigena, Eikenella corrodens, and Prevotella intermedia-like species with Bifidobacterium animalis subsp. lactis ” [2017]
  • ” In addition, populations of Escherichia coli, Veillonella spp. and Bacteroides vulgatus were decreased, while populations of Bifidobacterium genus and Lactobacillus spp. were increased with Lactobacillus reuteri” [2014]


Bottom Line



  • proton pump inhibitors
  • Lactobacillus reuteri
  • Lactobacillus kefiri
  • Vitamin D
