Tridge summary

A recent study by Chilean, Norwegian, and French scientists, led by Dr. Ruben Avendaño-Herrera, has confirmed the presence of Tenacibaculum piscium in Chilean farmed fish, expanding the bacterium's geographical distribution. The study, published in Transboundary and Emerging Diseases, analyzed 16 Chilean isolates of T. piscium from Atlantic salmon, rainbow trout, and Coho salmon, looking into its genomic features and virulence potential. The research also confirmed the pathogenic potential of T. piscium in fish, with varying mortality rates depending on the isolate and fish species. This finding highlights the need for a better understanding of this bacterium to develop effective strategies for preventing and treating tenacibaculosis in aquaculture.

An investigation by Chilean, Norwegian and French scientists confirmed the presence of Tenacibaculum piscium in Chile. The study “Isolation, identification, virulence potential and genomic features of Tenacibaculum piscium isolates recovered from Chilean salmonids”, recently published in the prestigious journal Transboundary and Emerging Diseases, is led by Dr. Ruben Avendaño-Herrera, Researcher at Universidad Andrés Bello and INCAR, accompanied by INCAR members, Dr. Mónica Saldarriaga and Rute Irgang, together with part of the Pharmacology in Veterinary Aquaculture research team, FAV, is the first to confirm the presence of Tenacibaculum piscium in Chile, thus expanding its geographical distribution. Until the present study, this bacterium of the genus Tenacibaculum had only been described in Norway (Olsen et al., 2020), with seven isolates recovered from skin ulcers, eroded tails/fins, normal skin and/or kidney of Atlantic salmon, trout rainbow and in the Napoleon species of ...
