21/12/2016: Olmix Group gold sponsor for the 2nd International Symposium on Alternative to Antibiotics

Olmix was Gold Sponsor for the 2nd international symposium on Alternative to Antibiotics in animal production (ATA), organised by USDA (United States Department of Agriculture) and OIE (World animal health organisation), at the OIE headquarter in Paris.

The symposium focused on the latest scientific breakthroughs and technologies that provide new options and alternative strategies for preventing and treating diseases of animals and reduce the use of medically important antibiotics in agriculture.
  


From Monday to Thursday 15th of December, six areas have been explored in detail through scientific presentations and expert panel discussions, including emerging topics related to gut health, such as characterisation of the microbiome and its interactions with the immune system with potential clinical applications.

This symposium also highlighted the emerging field and interest in treatments that demonstrate both antimicrobial and immune-enhancing capabilities.

In each session, invited speakers have given keynote lectures on the latest state-of-the-art in the area of interest, including Pr. Mustafa Berri, from INRA (French national agronomical research institute) that gave an oral presentation about green macroalgal sulfated polysaccharides (OLMIX MSP): a natural alternative to antibiotics via modulation of the intestinal immune response.

“Green algal sulfated polysaccharides: a natural alternative to antibiotics
via modulation of the intestinal immune response.”

In addition to oral and poster presentations, round table discussions of the conference topics enabled a fruitful dialogue between scientists and the food and feed industry as well as between researchers from all parts of the world.

Olmix, as a global know-how leader in the area of marine biotech applied to animal, plant and human health, actively supports research and knowledge exchange in this area and participated in the symposium to present its effective solutions for a healthy food chain, thanks to algae.

Hence this challenge can be achieved through innovative programmes that Olmix Group is currently working on thanks to its algae technology and and the unique molecules extracted, namely specific sulfated polysaccharides with biological properties (OLMIX MSP).

Olmix philosophy: one health thanks to algae
As a specialist in marine biotechnology, Olmix Group brings natural sources of nutrition and good health to plants, animals and people, for a complete and consistent food and health chain without pesticides, antibiotics and chemical additives.

Olmix, the Animal Care division of the group, places the animal at the interface of 2 major ecosystems: the external (housing, litter, air ...) and the internal (body, microbiota, nutrients, toxins ...).

Both influence each other and their balance will determine animal performance. Olmix addresses these two ecosystems with a range of solutions specifically designed for the farmer, the veterinarian or the feed miller.

Goal: to reach ‘antibiotic free’ production while improving farmers profit and animals well-being, thanks to algae.

Five functionalities, for complete programs for animals
Through innovations issued from algae, OLMIX has developed a full range of solutions acting on the 5 key factors influencing the welfare and the performance of livestock animals.

Thanks to algae, Olmix offers solutions which improve the hygiene of the animals by reducing the environmental humidity, enhance their immune defences, guarantee the digestive welfare, increase the digestive efficiency and fight mycotoxins present in the feed.

This global strategy contributes to reduce the use of antibiotics, to support the fight against antibiotic resistance and also to improve the quality of the final product.

Marine algae to reduce the use of antibiotics in farming
As part of a partnership with Olmix Group, Inra researchers have shown that a compound extracted from green algae inhibited the growth of pathogenic bacteria in vitro and stimulated the production of immunity mediators by intestinal epithelial cells.

This type of preparation could be used in livestock feed to improve animals’ resistance to infections and therefore reduce the use of antibiotics. These results were published on 8 March 2016 in the Journal of Applied Phycology.

Marine algae are chlorophyll-containing aquatic plants that grow on the seabed. They are classified in three groups depending on their pigments: brown algae (phaeophyceae), red algae (rhodophyceae) and green algae (chlorophyceae or ulvales).

The cell wall of these marine algae, are rich in sulfated polysaccharides, which possess physicochemical and biological properties that could have potential applications in the pharmaceutical industry, biomedicine, cosmetology and farming or as additives in human and animal food. Created in 1995, Olmix Group is specialised in promoting the use of green algae harvested in Brittany by processing them into innovative natural products for plant, animal and human nutrition and health sectors.

With the aim of identifying beneficial bioactive molecules, Olmix Group prepared an extract of sulphated polysaccharide known as marine sulphated polysaccharides (MSP), using Ulva armoricana green marine algae harvested in Brittany.

Within a research partnership between Olmix Group and the Inra Val de Loire Infectiology and Public Health Research Centre, an MSP was studied in vitro to test its capacity to inhibit bacterial growth and stimulate the production of immunity mediators.

The MSP’s ability to inhibit bacterial growth was observed on a panel of 42 strains of pathogenic bacteria isolated directly from livestock or their environment. The growth of Pasteurella multocida, Manheimia haemolytica, Erysipelothrix rhusiopathiae, Staphylococcus aureus, Streptococcus suis was inhibited by the action of MSP and more sensitive than Salmonella or E. coli.

MSP also induced an increased production of cytokines, in an in vitro system of differentiated porcine intestinal epithelial cells.

The stimulation of these immune mediators indicate a potential stimulation of intestinal immunity by MSP.

Marine algae represent a source sulphated polysaccharides (including MSPs, which could be used in livestock feed to inhibit the growth of pathogens and boost the immune response.

This could improve animals’ resistance to infections and reduce the use of antibiotics on farms.
