Two New Sturgeon Species are Susceptible to Acipenser Iridovirus European (AcIV-E) Infection

Pathogens, 2020
We report the first case of Acipenser iridovirus European (AcIV-E) infection in starry sturgeon (Acipenser stellatus) and in sterlet (A. ruthenus) reared in Northern Italy. During 2018, mortality began in A. stellatus and A.
