“…It is considered that fry and juvenile fish under 10 g in body weight are most susceptible to MABV (Nakajima et al, 1998), and the pathogenicity of MABV is higher in smaller fish (Sorimachi and Egusa, 1986;Kusuda et al, 1989). In our study, for fry and juvenile fish less than 1 g with clinical signs of ascites in the abdominal cavity and pale gills, their mortality was considered to be related to MABV infection.…”

Distribution of marine birnavirus in cultured olive flounder Paralichthys olivaceus in Korea

et al. 2008

Surveys of marine birnavirus (MABV) were undertaken in cultured olive flounder Paralichthys olivaceus from the south and west coastal areas and Jeju in Korea during the period January 1999 to April 2007. MABV was detected in all seasons from the fry, juveniles and adult fish from the areas examined. Evident cytopathic effects of the virus including rounding and cell lysis were observed in chinook salmon embryo (CHSE-214) and rainbow trout gonad (RTG-2) cells, but not in fathead minnow (FHM) and epithelial papilloma of carp (EPC) cells. Nucleotide sequences of the VP2/NS junction region of the Korean isolates showed 97.8% ~ 100% similarity, and they belonged to the same genogroup. Cross neutralization tests with serotype-specific rabbit antisera against MABV strains exhibited a close antigenic relationships between strains, and were distinct from infectious pancreatic necrosis virus (IPNV) strains. Coinfection of MABV with bacteria (Streptococcus iniae, Vibrio spp.) and viruses (nervous necrosis virus, lymphocystis disease virus, viral hemorrhagic septicemia virus) was observed.

“…aquaculture as cultured Seriola spp. are afflicted by a range of viral, bacterial, fungal, and parasitic disease agents, the majority of which have caused significant mortalities and require substantial monetary input to control (reviews in Egusa 1983;Benetti et al 1998;Nakajima et al 1998;Kusuda & Kawai 1998;Ogawa & Yokoyama 1998). Identifying the potential sources of disease in kingfish is an important step towards preventing epizootics, and assists the development of effective quarantine procedures and disease management strategies under culture conditions.…”

The prevalence and intensity of metazoan ectoparasites on the skin and gills of kingfish, Seriola lalandi lalandi (Carangidae), collected from White Island (n = 32), Ranfurly Banks (n = 7), and Three Kings Islands (n = 7), is reported. Kingfish were host to two monogenean and four copepod ectoparasite species, Benedenia seriolae, Zeuxapta seriolae, Caligus lalandei, Caligus aesopus, Neobrachiella spp., and Lernanthropus spp., respectively. B. seriolae and C. lalandei infect the skin, whereas the remaining parasites were located on the gills. All parasites exhibited considerable variability in the prevalence and intensity of infection. A few kingfish were completely devoid of C. aesopus, Neobrachiella spp., and/or Lernanthropus spp., whereas others were infected by moderate numbers of these species. However, all kingfish were infected by B. seriolae † Corresponding author. and Z. seriolae. Therefore, it appears that acclimation of wild kingfish from the east coast of New Zealand's North Island into captivity will lead to the transfer of both B. seriolae and Z. seriolae, and that effective quarantine measures will be required to avoid introducing these parasites into broodstock systems. The site preferences of B. seriolae, Z. seriolae, and C. aesopus were also investigated. B. seriolae exhibited a preference for attachment on the lateral surfaces of the skin behind the dorsal fin, but forward of the anal fin. Z. seriolae displayed a preference for attachment on gill arches 2 and 3, particularly in gill filaments located in the upper regions of the buccal cavity. C. aesopus most commonly occurred on the gill arch.

“…Ranaviruses (RVs) were initially identified in the mid-1960s (Granoff et al, 1966) but the implications of RV infections are still not completely understood. Ranaviruses have been associated with amphibians in Australia (Cullen and Owens, 2002), Asia (Zhang et al, 2001), Europe (Cunningham et al, 1996; Pasmans et al, 2008), South America (Zupanovic et al, 1998) and North America (Bollinger et al, 1999; Docherty et al, 2003; Greer et al, 2005; Jancovich et al, 1997, 2005), with fish species in Asia (Nakajima et al, 1998; Qin et al, 2003; Sudthongkong et al, 2002), Australia (Langdon and Humphrey, 1987), Europe (Ahne et al, 1997, 1989) and North America (Plumb et al, 1996), and with reptiles (Allender et al, 2006; De Voe et al, 2004; Hyatt et al, 2002; Johnson et al, 2007; Marschang et al, 1999, 2005). In addition to the major epidemics associated with RV infections in threatened amphibian species and commercially valuable fish, RVs are spread with fish, amphibians, and reptiles that are moved globally for bait, food, and as pets (Chinchar, 2002; Daszak et al, 1999; Jancovich et al, 2005; Picco and Collins, 2008; Schloegal et al, 2009).…”

Characterization of a PKR inhibitor from the pathogenic ranavirus, Ambystoma tigrinum virus, using a heterologous vaccinia virus system

et al. 2017

Ambystoma tigrinum virus (ATV) (family Iridoviridae, genus Ranavirus) was isolated from diseased tiger salamanders (Ambystoma tigrinum stebbinsi) from the San Rafael Valley in southern Arizona, USA in 1996. Genomic sequencing of ATV, as well as other members of the genus, identified an open reading frame that has homology to the eukaryotic translation initiation factor, eIF2α (ATV eIF2α homologue, vIF2αH). Therefore, we asked if the ATV vIF2αH could also inhibit PKR. To test this hypothesis, the ATV vIF2αH was cloned into vaccinia virus (VACV) in place of the well-characterized VACV PKR inhibitor, E3L. Recombinant VACV expressing ATV vIF2αH partially rescued deletion of the VACV E3L gene. Rescue coincided with rapid degradation of PKR in infected cells. These data suggest that the salamander virus, ATV, contains a novel gene that may counteract host defenses, and this gene product may be involved in the presentation of disease caused by this environmentally important pathogen.
