2nd CIVVET congress

Welcome on the 2^nd CIVVET congress page !

Papers expected in Veterinary Immunology, Infectiology & Vaccinology, with special focus on the “3Rs” approach

The Club d'Immunologie et de Vaccinologie Vétérinaire (CIVVet) was created from the former Réseau d'Immunologie des Animaux Domestiques (IAD) and federates the veterinary immunology community. It is run by a steering committee made up of scientists from the main national animal health research institutes (INRAE, CIRAD, ANSES and veterinary schools), who are keen to encourage exchanges between research teams and the emergence of national and international animal health projects, between academics and with private partners.

The congress is organized by a local committee, bringing together scientists from the IECM and BIOEPAR research units. The congress will take place over a day and a half, with a welcome for participants on April 14, 2025 at 1pm, until April 15 at 4pm.

The scientific program will combine plenary lectures by national and international experts, and presentations by researchers and PhD students. Young scientists, doctoral students and post-doctoral fellows, will play an important role in this conference, which will be held in English.

After the congress on Tuesday, attendants are given the opportunity to visit three Oniris places: at “la Chantrerie”, the Veterinary Hospital and the Experimental Platform dedicated to research in Aquaculture, or at “la Géraudière”, the B-FHIT platform (Bioproduction for Health and Innovative Therapy). Visits will last 1h to 1h30.

Discover the CHUV d'Oniris VetAgroBio or the Aquaculture Experimental Station

More informations about the CHUV: https://chuv.oniris-nantes.fr/
The Aquaculture Experimental Station is a rare facility in France. Few structures of this type exist (around ten private and public structures) and it is the only one in a veterinary school. The station is attached to the APPIFISH UMR BIOEPAR (INRAE/Oniris) research team and the SAESP (Animal and Public Health) teaching department. The two study models are the rainbow trout, Oncorhynchus mykiss, and the freshwater shrimp, Macrobrachium rosenbergii. The main areas of research are animal welfare, vaccine response, immune response, the development of infectious challenges and the kinetics of antibiotics in fish.

Discover the Bioproduction For Innovative Therapies (B-FHIT) platform

The Bioproduction For Innovative Therapies (B-FHIT) platform is unique in France in terms of the variety of its equipment and skills in the field of bioproduction. The platform is connected to the IECM (Oniris/INRAE) research laboratory and the Biology, Pathology and Food Science teaching department. It owns laboratory-scale and pilot-scale equipment that enables the impact of a process's change of scale on the quality attributes of biotherapies to be assessed.
As the upstream to downstream stages are carried out on the same site, the available tools enable biotherapies to be characterized throughout the production process. The research carried out focuses in particular on the challenges associated with the production of extracellular vesicles.
