Susceptibility of the fish cell line SAF-1 to betanodavirus.
Betanodavirus infections of fish, generally known as viral nervous necrosis or viral encephalopathy and retinopathy, are a serious threat to marine fish farming throughout the world (Munday, Kwang & Moody 2002). The culture of betanodavirus has proved complex because most commonly available fish cell lines do not allow the growth of these viruses, as reviewed by Munday & Nakai (1997). The diffi...
متن کاملBetanodavirus infection in the freshwater model fish medaka (Oryzias latipes).
Betanodaviruses, the causal agents of viral nervous necrosis in marine fish, have bipartite, positive-sense RNA genomes. As their genomes are the smallest and simplest among viruses, betanodaviruses have been studied in detail as model viruses by using a genetic-engineering system, as has occurred with the insect alphanodaviruses, the other members of the family Nodaviridae. However, studies of...
متن کاملSusceptibility of several species of Cyprinidae and Salmonidae freshwater fish to larval Gnathostoma nipponicum infection.
Susceptibility of five species of Cyprinidae and Salmonidae freshwater fish to the early third-stage larvae (EaL3) and advanced third-stage larvae (AdL3) of Gnathostoma nipponicum infection were examined. Two fish species inoculated orally with EaL3 were infected, and AdL3 were recovered from them with rate of 21.0% in Tribolodon hakonensis and 0.5% in Cyprinus carpio at 30 days postinoculation...
متن کاملAcute Toxicity of Nickel to Five Species of Freshwater Fish
Flow-through toxicity tests were conducted on common freshwater fishes: rainbow trout (Oncorhynchus mykiss), three-spined stickleback (Gasterosteus aculeatus), roach (Rutilus rutilus), perch (Perca fluviatilis) and dace (Leuciscus leuciscus), to estimate their sensitivity to acute toxicity of nickel. The 96-hour median lethal concentration (96-hour LC50) values obtained from the tests ranged fr...
متن کاملBehavioural thermoregulation in two freshwater fish species.
In the presence of a vertical thermal gradient, juvenile three-spined sticklebacks Gasterosteus aculeatus and minnows Phoxinus phoxinus positioned themselves higher in the water column compared with adult conspecifics. This result was consistent regardless of whether age cohorts were tested separately or together. Furthermore, juveniles but not adult fishes positioned themselves higher in water...
