Experimental infection reveals transmission of tilapia lake virus (TiLV) from tilapia broodstock to their reproductive organs and fertilized eggs

Early developmental stages of tilapia, including fertilized eggs were tested positive for TiLV in a previous study. We, therefore, hypothesized that infected broodstock is able to pass the virus to their reproductive organs and then to the fertilized eggs. In order to prove this hypothesis, Nile tilapia (Oreochromis niloticus) broodstock were experimentally infected with TiLV by intramuscular injection and non-infected broodstock were used as control group.
