New salmonid hosts for Tenacibaculum species: Expansion of tenacibaculosis in Chilean aquaculture
Abstract The success and sustainability of Chilean aquaculture largely depends on the control of endemic and emerging pathogens, including several species of the genus Tenacibaculum . Tenacibaculum dicentrarchi and “ Tenacibaculum finnmarkense ” have been detected and confirmed in Chilean Atlantic s...
