Two co-habitation studies with common carp were conducted to determine whether latent infections of koi herpesvirus (KHV) exist. Fish were exposed to KHV using two different temperature profiles, which induced low and high initial mortality associated with the virus. Subsequently, groups of fish were cohabited with naïve fish while others were not. Koi herpesvirus was reactivated in fish from three of the five experimental tanks. Reactivation of the virus occurred regardless of the initial mortality associated with the virus or whether fish were co-habited with naïve fish. The reactivation of virus in our experiments occurred several months after the initial exposure to KHV and appeared to be temperature dependant.
