Natural infection of hybrid sturgeon (Acipenser baerii♀×Acipenser schrenckii♂) with Nocardia seriolae and white sturgeon iridovirus: pathological and transcriptomic analyses

We report the initial occurrence of N. seriolae infection in cultured sturgeons. These findings could provide a theoretical basis for diagnosing and preventing this disease, as well as enhance the understanding of host-pathogen interactions in fish.
