Gut microbiota influences many aspects of host health, and one of the important roles is protection against pathogens. In this project gut microbiota will be studied by molecular and cultural methods and comparatively in in-vitro model (to be established within this research), in patients and healthy volunteer populations. Studied groups will include different populations of Clostridium difficile patients, patients with different antibiotic treatments and in long term prospect also patients colonized with ESBL or VRE. In-vitro model will be additionally used for studies of gut microbiota modulation with nonatibiotic approaches (phages, probiotics) and for interactions of C. difficile with gut microbiota.
Significance for science
Research of the role of gut microbiota for human health is currently one of most developing and promising fields in medical and microbiological research. Approaches could be divided into two groups: analysis of faecal/mucosal microbiota in individuals or analysis of microbiota within in vitro artificial systems. The results of the research proposed in this application will contribute to 1) basic knowledge of human gut microbiota, 2) role of microbiota in interactions with pathogens, 3) possibilities to modulate microbiota by antibiotics, probiotics, phages, 4) possibilities to use the gut microbiota modulatons for contol of important nosocomial pathogens (C. difficile; multi resistant Gram negative bacteria –ESBL; VRE...) for which the gut is one of the main reservoirs. It is expected that the results will be published in international journals with high impact and presented in national and international conferences.
Significance for the country
Gut microbial community has an important role in metabolism and immunity and is associated with numerous diseases. It was already recognized that development of new approaches to study and modulate gut microbial community is important task for scientific community, society and business sector. The main goal of proposed program is development of research platform for in-vitro studies of gut microbial communities. Developed system will enable basic scientific research of gut microbiome having direct impact on human health .  At the same time it is expected that we will develop new technologies having commercial impact. Developed gut model will enable in-vitro studies of early stage microbiota modulation products such as probiotics, antibiotics, antibacterial peptides and bacteriophages. Therefore, the model will become a basic for contract research activities that could be licensed or marketed through a start-up company. Optimization of nucleic acid and protein isolation protocols could lead to development of new and broadly applicable products such as isolation kits. Such products could be licensed or marketed through new companies. In all these cases Program will have direct economic impact by new high added value products, services and new employments of highly educated people. Developed in-vitro gut model will have a potential to connect several Slovenian research groups being active on the field. Such concentration of knowledge, people and resources will boost development and in addition increase the socio-economic impact of the Program. Researchers of the proposed Program consortium are connected internationally ensuring that developed in-vitro model will be used by global research and business community. Community will also benefit from bachelor, PhD and post doc students educated in the Program.
