MedAID Health Forum, new topic starting on 11 February 2019

Health forum discussion on Tenacibaculosis

Infection  with Tenacibaculum spp.

The MedAID Health Forum is conceived as a communication platform to gather field diagnosticians, laboratories, relevant authorities in charge of disease management in the Mediterranean mariculture and other stakeholders.

Forum discussion started in July with a key topic, Sparicotylosis followed by second discussion on Viral encephalopathy and retinopathy (VER/VNN) during the autumn, and now we are announcing a new topic on tenacibaculosis, infection of marine fish species with bacteria from the genus Tenacibaculum.

Tenacibaculum infection (previously known as flexibacteriosis) is disease associated to the infection with bacteria from the genus Tenacibaculum. The disease affects variety of marine fish species and in some marine areas or in recirculation systems, the infection severely threatens production with mortalities rising over 30%. Pathological changes are generally affecting fish from nursery phase to pre-growing fish, up to 80-100 grams average weight. Prevalence and intensity of the infections are varying in relation with environmental parameters and zootechnical/rearing conditions and are influenced with handling, mechanical lesions or stress and interfering parasitic infestations. Many studies support the hypothesis on Tenacibaculum spp. as opportunistic pathogen that primarily causes extensive skin lesions and gill abrasion, and subsequent systemic infections.

If you want to know more about Tenacibaculosis, visit the MedAID blog and read the Mini-review written by Alain Le Breton, and to learn more about all aspects of this devastating disease join on 11th February the MedAID Health Forum, discussion about tenacibaculosis which will be moderated by Jean-Francois Bernardet, INRA, Centre de Recherches Virologie et Immunologie Moleculaire, France and Alain Le Breton, VET’EAU,France.

Objectives of the Tenacibaculosis discussion

  • To exchange the recent scientific data of a practical implication, with the health experts dealing with the problem caused by tenacibaculosis in farmed fish
  • To help farmer understanding the circumstances for clinical diseases appearance
  • To help farmers implementing the zoosanitary measures aiming to prevent tenacibaculosis
  • To share “tips and tricks” of farmers about how to deal with Tenacibaculum spp. infected fish batch from one area to help farmers in other areas with the same problem

Process proposed to focus the discussion

  • The farm health experts are encouraged to share their valuable practical knowledge; the current prevention strategy should be profoundly evaluated and analyzed.

The topics that should be discussed

  • Epidemiology of tenacibaculosis in seabass and seabream
  • Zoosanitary rules
  • Good aquaculture practices in prevention of Tenacibaculum spp. infection
  • Diagnostic methods choice and use in different diagnostic capacity labs
