Date: 26 Sept 2022, Time: 2pm CEST
Duration: 1.5 hours
Abstract:
The more we look the more we see. The tremendous developments in microscopic and cell culture techniques over the past 10 years have shown us more and more that we are never alone. We are surrounded by billions of microbes of all kinds, fungi, yeasts, viruses and bacteria. These microbes live together in groups on our skin, in our mouth, the genital tract and most of all in our intestines.
Modern “omics” techniques allow us to identify the genes specific to each group of microbes and thus identify the microbiomes (all the genes) and the microbiota (all the microbes that contain those genes) in the different bodily environments. This gives a huge amount of data that we can properly store and analyse with modern informatics techniques. Defining healthy microbiomes, preventing disease, fighting disease, keeping our food and environment healthy, these are the challenges we face today.
The mission of the GHI Food Microbiology Working Group is to strive for evidence-based and rational harmonization of criteria, regulations and legislation relevant to the microbiology of foods. The current webinar will focus on specific challenges in microbial food safety and quality that can be affected by microbiomes.
This GHI webinar and interactive sessions, will be expertly chaired by Dr. Diana Bogueva, GHI Working Groups Director.
Microbes, microbiota and microbiomes; their role in humans, animals, plants and the environment.
Dr. Stanley Brul, is Professor of Molecular Biology and Microbial Food Safety, Swammerdam Institute for Life Sciences, University of Amsterdam, NL and Co-Chair of the GHI Food Microbiology Working Group.
Abstract:
Microbes are everywhere in the surroundings. They are the most ancient living systems on earth and have since long established a mostly mutually beneficial relationship with humans, animals, plants and other microbes occurring in special environmental niches. The question arises, who are these microbes and what are their functions, are there common elements between human, animal, plant and environmental microbial consortia and how do we analyse these complex microbiota and their encaged microbiomes. The session will discuss the composition of the various sites of microbial occurrence and indicate also what happens if a less preferred, generally non stable, state is established in these niches. Inflammatory disorders and/or microbial infection ensues associated with pathogenic function, antibiotic resistance and often food-safety. The seminar will discuss the options that can be explored to study host-microbe interaction starting with cohort analyses and linked bioinformatic tools. We will also address how microbes move throughout the holomicrobiome and what the current state of the art is in in vitro gut-on-a-chip systems to study host-microbe interaction. The models discussed will be introduced from a functional perspective as well as the compounds that are being seen as important mediators of the interaction between the microbes and their hosts.
The Microbiome from a Food Safety Point of View
Dr. Rozita Spirovska Vaskoska, Senior Scientist at the Australian national science institute CSIRO
Abstract:
Rozita Vaskoska will further discuss the microbiome from a food safety point of view. From the perspective of food safety, the microbiome is a diverse concept that includes the gut microbiome of food producing animals, plants, food, the environmental microbiome and the human microbiome. This presentation will provide an overview of the findings for each of these microbiome concepts, the role they play in food safety, as well as the benefit of microbiome tests and findings for predicting or controlling risks in the food chain. The presentation will conclude with a case study on the use of bacteriophages as food safety control measures in the context of the microbiome.
