Using meta-technologies in understanding how the microbiota affects...

Speaker: Prof Joël DORE, MICALIS, Metagenopolis, INRA, Paris, France

We are an ecosystem, in constant symbiosis between host and microbes. In spite of considerable progress in medicine and infection control, chronic disease are developing. A disruption of host-microbes symbiosis is the common thread in chronic conditions. Prevention is critical considering mucosal barrier, immune tolerance, redox balance and microbiota to restore symbiosis. Microbiota modulation should be considered as a target and we should talk more about Nutrition Ecology.

Approaches to identify biomarkers for intestinal health and the first tools...

Speakers: Prof Filip VAN IMMERSEEL, Faculty Vet Medicine, Ghent Univ, Belgium

New technologies are promising to develop biomarkers of gut health. The most important would be to have predictive biomarkers to anticipate gut health disturbance. Today, macroscopic (ballooning, tonicity, residues…) and microscopic (villi, tight junctions, …) observations help to better appreciate gut health condition but inflammation, immune parameters and microbiota are also important. Microbiota signature is associated with gut disorders, but microbial functional activity is even more predictor of such dysbiosis.

Speaker: Dr Lisa WILLIAMS, Swansea, UK

Campylobacter is not a harmless commensal, affecting bird health, welfare and performance. There is a changing host-pathogen dynamic, with possible campylobacter mutation, including bacteria gene transfer. Exposure is difficult to prevent and the best way forward is to improve chicken resistance.

Why do we need to understand microbial pathogenesis?

Tue, 02 Jul 2019 00:00:00 GMT

Speaker: Prof Mark STEVENS, the Roslin Institute & the Royal School of Vet Studies, Univ of Edinburgh, UK

Identification of microbiota associated with pathogen resistance may lead to rationally selected probiotics and feed additives. Editing, ablation and adoptive transfer of components of the immune system will be key tool to dissect avian responses required for protection.

Antibiotics, probiotics and anti-virulence: balancing efficacy and evolution

Tue, 02 Jul 2019 00:00:00 GMT

Speaker: Prof Sam BROWN, Georgia Institute of Technology, USA

Drug resistance is an important issue. What about evolutionary robustness in relation of treatment efficacy? Focusing on anti-virulence and anti-resistance features become more and more critical for the development of future solutions vs traditional anti-microbial strategies. Conditional strategies need to be developed to efficiently fight antimicrobial resistance.

Histomonosis and the molecular repertoire of Histomonas meleagridis

Tue, 02 Jul 2019 00:00:00 GMT

Speaker: Prof Michael HESS, Clinic for Poultry & Fish Medicine, Christian Doppler Lab, Univ of Veterinary Medicine, Vienna, Austria

Blackhead is a serious welfare issue with no therapeutic and prophylactic drugs. Scientists investigate with molecular technologies the transcriptome and the proteome including exo-proteome to better understand virulence of this pathogen and develop vaccine alternatives.

Steering immune responses using nutritional interventions: should it be pro-...

Tue, 02 Jul 2019 00:00:00 GMT

Speaker: Prof Adrian SMITH, Oxford, UK

How can we analyze nutritional interventions? Assessing effects of manipulations requires measurements of lots of parameters, applying multiple methods (immunology, histology, sequencing…), employing both experimental and field systems (germ-free, genetics, specific pathogens…). We deal with a complex moving target!

What is an ideal feed additive for broilers and how can we assess this?

Tue, 02 Jul 2019 00:00:00 GMT

Speaker: Prof Steven RICKE, Director of Food Safety, Univ of Arkansas, USA

Alternative to antibiotics must be acceptable and effective with detectable and consistent improvements in pathogen control and in animal performance. Modes of action need to be known and multiple hurdle approaches need to be developed.

Enhancing the sustainability of poultry systems

Tue, 02 Jul 2019 00:00:00 GMT

Speaker: Prof Ilias KYRIYAZAKIS, School of Natural and Environmental Sciences, Newcastle, EU

It is important to consider the genetic change and its implications for performance using different feeding strategies. There are alternatives to imported soy in EU that can maintain the environmental impact but not for nitrogen excretion. Modelling will be used to address least cost and environmental impacts.
