Maternal microbiota sets neonatal innate immune system development

Dr Gomez

Dr Mercedes Gomez de Agüero from the University of Bern in Switzerland was invited by the scientific committee of the International Society of Microbiota to present her researches about the maternal microbiota and the neonatal innate immune system development.

The following questions will be answered by Dr Gomez during the congress:

  1. When the impact of the microbiota in the development of the immune system starts?
  2. What is the role played by the maternal antibodies in the impact of maternal microbiota in the development of neonatal immune system?
  3. Which kind of bacterial products would be involved in the effect of maternal microbiota in the shaping of the neonatal immune system?

According to Dr Gomez, Mammalian, born from a sterile environment in the maternal uterus, get colonized by a millions of microorganism at birth. How the immature neonatal immune system of the newborn is prepared to this colonisation was not clearly understood. Using an auxotrophic genetically modified strain of Esc Maternal microbiota sets neonatal innate immune system development herichia coli, we reversible colonised pregnant germ free mice and analysed by flow cytometry and RNA sequencing the impact of maternal microbiota on the development of immune system in the pups. [...] The offspring from gestational colonized mothers were protected against microbiota challenge preventing bacterial translocation to mesenteric lymph nodes and modulating gene expression. Our results reveal the tremendous role played by maternal microbiota and antibodies in setting the baseline of the innate immune system in the neonates.

Bacteriophages for improving human health: from food additives to dietary supplements

A Sukalvelidze Microbiota Paris2016

The scientific committee of the International Society of Microbiota is honoured to welcome Dr. Alexander Sulakvelidze, Editor-in-chief of Bacteriophage for the 4th edition of Targeting Microbiota World Congress.

During the congress, Dr. Sulakvelidze will talk about bacteriophages for improving human health: from food additives to dietary supplements. According to Dr. Sulakvelidze, the emergence of drug-resistant bacteria has rekindled interest in potential utility of lytic bacteriophages for managing bacterial infections. While most public attention has focused on the use of phages for treating human infections, there are currently no FDA-approved phage products available for human therapeutic applications. It is anticipated that such products will be gradually approved and marketed over the next several years.  Meanwhile, lytic bacteriophages are already improving our health by enhancing our food safety; e.g., several FDA-approved phage-based products are currently on the market for “phage biocontrol” applications. Moreover, application of bacteriophages as dietary supplements / probiotics is also gaining an increased attention, as phages are increasingly being considered for targeted fine-tuning of the human microbiota for health benefits. 

The presentation will give the audience a current perspective about the history of bacteriophage therapy research and the crucial regulatory and human safety issues concerning the use of bacteriophages in various applications ranging from food safety (“phage biocontrol”) to dietary supplements / probiotics.

Role of the microbiome in inflammatory bowel diseases: using multi-omics datase

Knut Rudi Microbiota

The microbial ecosystem residing in the human gastrointestinal tract plays an intimate role in the development and well-being of their human host. The gut commensal microbes reside in synergy with the host, undertaking wide range of functions that benefits themselves and their host. These host-associated microbial communities that share different functional genes between distinct bacterial species are increasingly associated with horizontal gene transfer (HGT).

During Targeting Microbiota World Congress, Dr Knut Rudi from the Norwegian University of Life Sciences will discuss the current status and future developments in their knowledge about the infant gut microbiota mobilome will be discussed.

Marvin Edeas from Institut Cochin, INSERM U1016 will present the challenge to find strategies to modulate the quality and diversity of microbiota

Microbiota marvin edeasOur aim is to highlight the subtle relationship that exists between microbiota and mitochondria. Microbiota targets mitochondria by modulating the Reactive Oxygen Species (ROS) production and the mitochondrial activity through interactions with toxins, proteins or other metabolites released by gut microbiota. The intriguing relationship that exists between mitochondria and microbiota is strengthened by the probable prokaryotic origin of mitochondria. Emerging data implicates a role for ROS, nitric oxide, Short Chain Fatty Acids and hydrogen sulfide in the cross-talk between microbiota – mitochondria and REDOX signaling. Several studies have shown that microbiota act and modulate mitochondrial activity, and use it as a relay to strengthen host-microbiotal interaction. This modulation depends on the gut bacterial strain quality and diversity to increase its pathogenic versus beneficial effects. Furthermore, based on conclusions from new studies, it is possible that microbiota can directly interact with the host cell gene expression by favoring bacterial and mitochondrial DNA insertion in the nuclear genome. The emerging knowledge of mitochondria-microbiota interaction may be of great importance to better understand the mechanism of mitochondrial and metabolic diseases, and the syndromes associated with change in quality and quantity of microbiotal species.  We suggest that microbiota via mitochondrial modulation influence cell homeostasis and metabolism. The challenge will be to find strategies to modulate the quality and diversity of microbiota rather than acting on microbiota metabolites and microbiota related factors. The medicine of tomorrow will be completely personalized. Firstly there will be a test to show the quality, quantity and diversity of microbiota, and secondly a preventive or therapeutic strategy will be administrated (probiotics, diet, prodrug or fecal transplantation). The era of digital medicine is here.

Dr. Jasper will hightlight the age-related immune senescence and microbiota dysbiosis

JasperDr. Henri Jasper, Professor and CSO of the Buck Institute for Research on Aging in Novato, Canada, will give a presentation about Age-related immune senescence and microbiota dysbiosis: lessons from the fly, on the 4th World Congress on Targeting Microbiota.

Dr. Jasper’s lab studies the effects of aging on the intestinal microbiota, using Drosophila as a genetically accessible model system. Recent studies have uncovered a critical role for immune deregulation in the development of microbiota dysbiosis in aging animals. The work established that the intestinal epithelium of aging flies develops an inflammatory condition that is characterized by hyper activation of the Relish-NFkB signaling pathway, and results in expansion of the commensal microbiota, a secondary inflammatory response, and over-activation of intestinal stem cell proliferation. By preventing NFkB deregulation, the authors are able to delay these phenotypes and extend lifespan. Current work focuses on age-related changes in microbiota composition and compartmentalization, and new findings will be presented at the conference.

Skin microbiota: Towards a new era in dermocosmetics/ Dermatology

skin microbiota dermatology marvin edeasThis review was based on symposium on skin microbiota which was organized by the International Society of Microbiota on June 17, 2015, Paris, France. Marvin Edeas, Chairman of the Scientific Committee of ISM stated: "This review shortly characterises skin microbiota and their functions. The impact of external factors such as xenobiotics, traumatization, UVB light, cosmetic products and antiseptics are discussed. Strategies to target axillary microbiota to prevent body odour, as well as potential targets to manipulate microbiota in cosmetics and athopic dermatitis are outlined with examples. In future we may expect that knowledge of skin microbionome will allow development of wide range of cosmetical products and stratify patient and people with high predispostion to disease subsets, predict the best treatment or preventiv modality and outcome and introduce new treatment strategies by targetely manipulation of microbial communities."

The ISM awarded Pr Iradj Sobhani for his Scientific Contribution during the 3rd World Congress on Targeting Microbiota

sobhani iradj During the 3rd World Congress on Targeting Microbiota held at Pasteur Institute from October 21 to 23, Pr Iradj Sobhani from Hôpital Universitaire Henri Mondor, France gave a strategic presentation about "Cancer & Microbiota: Potential of fecal microbiota for early-stage detection of colorectal cancer".

 

According Pr Sobhani: "Colorectal cancer (CRC) is one of the main major problems in health care. The incidence is growing in western countries and no evident cause is found although germline DNA mutations in less than 5% of patients are identified and environment factors such as food, style of life, medicine, etc... are now suspected to induce majority of cancers. Exhaustive quantitative and qualitative evaluation of all factors from the environment is not possible. The microbiota may be considered as platform offering host and environment interactions for studying CRCs. And growing data show specific changes in microflora (dysbiosis) in colon cancer patients’ stools or adherent to the colonic mucosa. The hypothesis that colon cancer might be a bacteria-related disease is suggested and perspectives discussed."

The Scientific Committee of the International Society of Microbiota was delighted to award Pr Sobhani for this strategic presentation and his scientific contribution during the international congress.

ADahlgren

Dr. Dahlgren is a Swedish physician specialised in International Public Health and is affiliated to Karolinska Institutet Department of Microbiology, Tumor and Cell biology, in Stockholm Sweden. His current field of research is the clinical application of Anaerobically Cultivated Intestinal Microbiota, especially in Recurrent Clostridium difficile infections, a major public health concern in US, Canada, Europe and other countries. Since 2003 he in an advisor to the Bhutan Health Trust Fund and the Ministry of Health in the Kingdom of Bhutan.

During Targeting Microbiota World Congress 2005, Dr Dahlgren gave a short oral presentation about "anaerobically cultivated human intestinal microbiota". 

For almost 20 years, Dr Dahlgren's team have produced a human intestinal microbiota under strict anaerobic conditions, as an in vitro batch culture. This cultivated microbial ecosystem designated anaerobic cultivated human intestinal microbiota (ACHIM) has been reinoculated every second week during the years into new production batches. The cultivated microbiota has retained a microbial diversity comparable to that of feces from healthy donors, containing the major bacterial phyla Firmicutes, Bacteroidetes, Proteobacteria and Actinobacteria, as confirmed by gene sequencing.This batch-cultured microbial ecosystem has been tested for safety and clinical efficacy for many years in more than 400 patients, most of them suffering from recurrent Clostridium difficile-infection (RCDI).
