“…FV3 was originally isolated from an asymptomatic leopard frog Rana pipiens in North America (Granoff et al 1966). However, other strains of FV3 recognised by the ICTV have been implicated in epidemic disease incidents in amphibians in Europe, the Americas and Asia (Wolf et al 1968, Cunningham et al 1996, Zupanovic et al 1998, Weng et al 2002. In the UK, disease epidemics appear to be causing localised long-term declines in populations of the common frog Rana temporaria (Teacher et al 2010).…”

Ranaviruses are an emerging group of viruses and have been implicated in an increase of epidemics in susceptible species. They have a wide host range, infecting fish, amphibians and reptiles, with some isolates able to infect multiple species from different animal classes. Whilst some information exists on the pathogenicity of ranaviruses to novel hosts, there is none on the pathogenicity of fish ranaviruses to amphibians; this information is needed to develop measures to prevent the further spread of ranaviral disease in the aquatic environment. We undertook bath infection trials to assess the susceptibility of the European common frog Rana temporaria to 9 ranavirus isolates comprising doctor fish virus (DFV), European sheatfish virus (ESV), epizootic haematopoietic necrosis virus (EHNV), guppy virus 6 (GV6), pike-perch iridovirus (PPIV) and short-finned eel ranavirus (SERV) from fish hosts, and Bohle iridovirus (BIV), frog virus 3 (FV3) and Rana esculenta virus 282/I02 (REV) from amphibians. Animals were challenged as tadpoles at 15 and 20°C and as recent metamorphs at room temperature (20 ± 1°C) to investigate the effect of temperature and amphibian developmental stage on virus pathogenicity. Tadpoles were susceptible to FV3, PPIV and REV, but refractory to the other ranaviruses. Post-metamorphs were susceptible to FV3 and REV but refractory to BIV (the other ranaviruses were not tested). Significant mortality occurred in post-metamorphs and in tadpoles challenged at 20°C but was low in tadpoles challenged at 15°C. This study presents the first evidence of mortality in an amphibian species after challenge with ranavirus originally isolated from fish.

“…RUK in the UK; Hyatt et al 2000) have been implicated as a cause of mass amphibian deaths worldwide (Hyatt et al 2000). In addition to FV3, other important pathogenic ranaviruses are the tiger frog virus (TFV) (Weng et al 2002) and Ambystoma tigrinum stebbensi virus (ATV) (Jancovich et al 1997, Bollinger et al 1999. Ranaviruses have been identified as the cause of explosive disease outbreaks, with high mortality rates due to systemic disease in frogs in the US (Majji et al 2006), Australia (Speare & Smith 1992), Croatia (Fijan et al 1991) and the UK (Cunningham et al 1996(Cunningham et al , 2007, and in salamanders in the US (Jancovich et al 1997, Docherty et al 2003 and Canada (Bollinger et al 1999).…”

We describe the pathology, isolation and characterisation of a virus responsible for an outbreak of a systemic haemorrhagic disease causing high mortality in tadpoles of the common midwife toad Alytes obstetricans in the 'Picos de Europa' National Park in northern Spain. The virus, provisionally designated as the common midwife toad virus (CMTV), was isolated from homogenates of visceral tissue from diseased toad tadpoles following inoculation on epithelioma papulosum cyprini (EPC) cells. Molecular characterisation of the virus, including sequence analysis of the DNA polymerase and major capsid protein genes, showed that the isolated virus was a ranavirus with marked sequence identity to other members of the genus Ranavirus. A rabbit antiserum raised against purified virions was prepared and used to definitively demonstrate systemic distribution of the virus in diseased tadpoles, indicating that the isolated virus was the primary pathogen.

“…Ranaviral disease outbreaks have been increasingly recognized in captive amphibians, especially those reared under intensive aquaculture conditions (Weng et al 2002, Majji et al 2006, Miller et al 2007, Mazzoni et al 2009, Geng et al 2011 or in pet, zoo, and aquarium collections (Miller et al 2008, Pasmans et al 2008, Driskell et al 2009). However, it is possible that outbreaks of ranaviral disease have been overlooked in captive settings because clinical and pathological findings overlap other amphibian diseases and, until recently, ready access to specific diagnostic tests was limited (Pessier & Mendelson 2010).…”
