Our contamination aware approach is crucial
By carefully controlling for contamination at every step of microbiome analysis, we provide reliable data that reflect the actual bacterial load of tissues rather than contaminants.

Beyond the human gut microbiome
The microbiota is not only located in the gut. It expands to every part of the body, ranging from very high to very low bacterial biomass. Learn more by travelling through our microbiome atlas.
Vaiomer tailor - made metagenomics
Challenging low bacterial biomass samples are now accessible thanks to our specifically optimized and contamination-aware metagenomic workflow. Discover our services.

“at the International Clinical Research Center (ICRC) in Brno, Czech Republic, we were able to use Vaiomer’s collected information about the blood microbiota in humans and in mice models to understand the pathogenesis of leukemia and the effect of different diets on systemic inflammation. This information is exceptionally accurate and provide us with a dynamic insight into host-microbiota interaction during pathogenesis”

Altered intestinal permeability (also called ‘leaky gut’) is attracting growing scientific interest due to its involvement in numerous health conditions including, most importantly, autoimmune diseases. The JPI-funded projet ‘MaPLE’ (Microbiome mAnipulation through Polyphenols for managing gut Likeness in the Elderly) aims to demonstrate that dietary polyphenols may preserve intestinal permeability in the elderly. A pivotal and essential role in this project is played by the assessment of bacterial translocation through the blood microbiomics analyses that Vaiomer can provide.

Translocation of bacteria from the gut into the blood has been defined as a key factor contributing to inflammation and disease progression in the last decade. However, characterization of the translocated bacteria has remained elusive due to technical issues, that we have been able to sort out with an extremely efficient collaboration with Vaiomer.

One of the goals of our research is to understand how the unique immunological state of pregnancy protects the fetus from rejection without compromising the mother. Our collaboration with Vaiomer is examining this from a unique perspective by using their novel disruption and extraction methodologies to determine if pregnancy alters the blood microbiome. We will also test if this information can be used as an early discovery platform for the prediction of poor pregnancy outcomes associated with infection, such as preterm birth

Thanks to the expertise of Vaiomer, we have found a dysbiosis of the blood and brain microbiota of 5XFAD mice, transgenic mouse model of Alzheimer’s disease, compared to wild-type littermate animals. These striking results pave the way for new biomarkers of the disease and unexpected therapeutic strategies.

« With the development of immune checkpoint inhibitors in thoracic oncology, there are more and more evidences of the impact of gut microbiota on the efficacy of these drugs. In this context, Vaiomer offers the exciting opportunity to get a reflect of the gut microbiota profile on a simple blood test in patients with lung cancer treated with immunotherapies.”

Translocation of the gut microbiota into the circulatory system modulates the inflammatory response in many diseases, including liver disease. The nature and composition of the microbiota that enters and circulates in different compartments of blood can be explorer by the tools of Vaiomer. Indeed, independent of Vaiomer, positive cultivation in selected patient samples demonstrated circulating viable bacteria. Moreover, members of circulating microbiome showed strong correlation with inflammatory cytokines, which deliver comprehensive data of circulating microbiome in different blood compartments and their association with systemic inflammation, at least in liver diseases.

We left our unique liver biopsies from overweight human subjects with steatosis and from lean non-steatotic subjects to Vaiomer for evaluation of the bacterial metagenome in human liver tissue. With the invaluable and professional help from the Vaiomer team, we are now interpreting the exciting bacterial DNA results and we look forward to provide a window to the hepatic relative proportions of taxa in the two groups. The potential bacterial ‘fingerprints’ of bacteria in human liver tissue that may arise from our collaboration with Vaiomer may procure a new understanding of how gut bacteria are involved in the development metabolic disease
