First symposium on diseases in Asian aquaculture. 26-29 November 1990. Bali, Indonesia.

Ultrastructural observation on fish rhabdoviruses, hirame rhabdovirus (HRV): Rhabdovirus olivaceus, infectious haematopoietic necrosis virus (IHNV), pike fry rhabdovirus (PFR), eel virus of America (EVA) and eel virus of Europe (EVEX) on RTG-2 cells was studied at 12 hr post-infection. Virus particles were found budding on the cell surfaces and were never observed in the vacuoles. Club-like or cord-like structures were easily observed on the cell surface of HRV infected cells. Appearances of these structures sometimes varied from club-like to cord-like structures, but all of them showed high electron density and included microfilaments. Most of them contained many viral particles on the surface. However, it was difficult to find such club- or cord-like structures on other fish rhabdoviruses-infected cells. PFR and EVEX infected-cells showed other rod-like or bubble-like structures on the surface, composed of membrane only.
