Biotechnology advancements in South American poultry and salmon vaccines

Researchers in Argentina and Chile have made significant advancements in veterinary vaccines targeting specific regional diseases in the poultry and aquaculture sectors.

In Argentina, the National Institute of Agricultural Technology (INTA) and Laboratorios INMUNER have developed an attenuated vaccine for a specific variant of avian infectious bronchitis. This formulation, based on the A13 strain, addresses a variant for which no specific commercial options previously existed in the Argentine market. The product has received approval from SENASA and is now available for the poultry industry.

In Chile, a research team led by the Universidad Andrés Bello and the Quintay Marine Research Center (CIMARQ) has progressed in developing a vaccine against tenacibaculosis, a bacterial disease affecting Atlantic salmon. The study, published in the Journal of Fish Diseases, tested three experimental prototypes. The prototype TdCh05 demonstrated the highest efficacy, reducing cumulative mortality to 50% compared to 73.3% in the control group. While promising, researchers noted that further studies are required before the vaccine can be implemented in production environments.
