Localization of RNA replication to intracellular membranes is a universal feature of positive-strand RNA viruses. The betanodavirus greasy grouper (Epinephelus tauvina) nervous necrosis virus (GGNNV) is a positive-RNA virus with one of the smallest genomes among RNA viruses replicating in fish cells. To understand the localization of GGNNV replication complexes, we generated polyclonal antisera...
An acute mortality caused by an uncertain agent occurred in wild golden grey mullet (Liza auratus) population in the Iranian side of the Caspian Sea in February, 2004. Clinical signs of the moribund fish were erratic behavior such as spiral swimming, belly-up at rest and over inflation of swim bladder. Histological examination of brain of dead fish revealed hyperaemia, degeneration and necrosis...

Outbreaks causing mass mortalities have been observed in the golden grey mullet (Liza auratus) population in southern coastal area of the Caspian Sea since 2002. The clinical signs include neurological abnormalities, such as erratic swimming behavior, spiral swimming, belly-up at rest and over inflation of the swim bladder. Three hundred and twelve samples of moribund fish with sizes that range...
The post-challenge immune and histopathologic responses of hybrid striped bass vaccinated with a DNA vaccine encoding the Mycobacterium marinum Ag85A gene and subsequently challenged with M. marinum were investigated. Juvenile hybrid striped bass Morone saxatilis x M. chrysops were injected intramuscularly with 25 or 50 microg DNA plasmid and developed significant specific protective responses ...
