Betanodaviruses, members of the Nodaviridae family, are the causative agents of viral nervous necrosis in fish, resulting in great economic losses worldwide. This is the first case study describing the detection and confirmation of viral nervous necrosis in pot‐bellied seahorses ( Hippocampus abdominalis ) in Australia. Clinical signs of this infection in the seahorses included whirling, floating and cessation of feeding. Hist...

Carp ( Cyprinus carpio L.) is a pest species in Australian waterways, and cyprinid herpesvirus 3 (Cy HV ‐3) is being considered as a potential biological control (biocontrol) agent. An important consideration for any such agent is its target specificity. In this study, the susceptibility to Cy HV ‐3 of a range of non‐target species ( NTS ) was tested. The NTS were as follows: 13 native Australian, and one introduced, fish spec...

Molecular ( PCR ) diagnostic tests for the detection and identification of aquareovirus in general, and Tasmanian Atlantic salmon reovirus ( TSRV ) specifically, were developed, and their diagnostic sensitivity and specificity were determined and compared with virus isolation in cell culture. Intralaboratory and interlaboratory comparison of PCR (conventional hemi‐nested RT‐PCR & RT ‐ qPCR ) and virus isolation in cell culture...
