Francisella philomiragia, a bacteria associated with high mortalities in Atlantic salmon (Salmo salar) cage-farmed in Llanquihue lake

Francisella philomiragia was isolated from Atlantic salmon cage-farmed in the Llanquihue lake with outbreaks of a granulomatous disease, with high rates of morbidity and an accumulated mortalities between 5% to 20%. The isolates had 100% similarity with F philomiragia ssp noatunensis or E piscicida isolated in Atlantic cod, 99% similarity with Francisella sp. detected in tilapia from Asia and Central America and 99% of similarity with the reference strain F philomiragia through 16s rDNA phylogenetic analysis.
