| ranavirus phylogeny and differentiation based on major capsid protein, dna polymerase and neurofilament triplet h1-like protein genes. | in this study, we developed new methods for differentiation of ranaviruses based on polymerase chain reaction and restriction enzyme analysis of dna polymerase and neurofilament triplet h1-like (nf-h1) protein gene. using these methods, we were able to differentiate the 6 known ranaviruses--bohle iridovirus (biv), european catfish virus (ecv), epizootic haematopoietic necrosis virus (ehnv), european sheatfish virus (esv), frog virus 3 (fv3) and singapore grouper iridovirus (sgiv)--with 3 less ch ... | 2009 | 19694168 |
| quantitation of ranaviruses in cell culture and tissue samples. | a quantitative real-time pcr (qpcr) based on a standard curve was developed for detection and quantitation of ranaviruses. the target gene for the qpcr was viral dna polymerase (dnapol). all ten ranavirus isolates studied (epizootic haematopoietic necrosis virus, ehnv; european catfish virus, ecv; european sheatfish virus, esv; frog virus 3, fv3; bohle iridovirus, biv; doctor fish virus, dfv; guppy virus 6, gv6; pike-perch iridovirus, ppiv; rana esculenta virus italy 282/i02, rev282/i02 and shor ... | 2010 | 21087639 |
| selected emerging diseases of amphibia. | this review summarizes the most recent updates on emerging infectious diseases of amphibia. a brief summary of batrachochytrium dendrobatidis history, epidemiology, pathogenesis, life cycle, diagnosis, treatment, and biosecurity is provided. ambystoma tigrinum virus, common midwife toad virus, frog virus 3, rana grylio virus, rana catesbeiana ranavirus, mahaffey road virus, rana esculenta virus, bohle iridovirus, and tiger frog virus ranaviruses are extensively reviewed. emerging bacterial patho ... | 2013 | 23642863 |
| susceptibility of the european common frog rana temporaria to a panel of ranavirus isolates from fish and amphibian hosts. | 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 spr ... | 2013 | 23574703 |
| susceptibility of black bullhead ameiurus melas to a panel of ranavirus isolates. | ranaviruses are considered a serious threat to lower vertebrates, including fish, amphibians and reptiles. however, epidemiological data on these agents are lacking, and further investigations are needed to understand the role of carriers and to update the list of susceptible hosts. we carried out various experimental infections under controlled conditions to contribute to the current knowledge on the susceptibility of black bullhead ameiurus melas to european catfish virus (ecv) and other ranav ... | 2010 | 20815324 |
| long-term study of an infection with ranaviruses in a group of edible frogs (pelophylax kl. esculentus) and partial characterization of two viruses based on four genomic regions. | several edible frogs (pelophylax kl. esculentus) collected into a single group from various ponds in europe died suddenly with reddening of the skin (legs, abdomen) and haemorrhages in the gastrointestinal tract. ranavirus was detected in some of the dead frogs using pcr, and virus was also isolated in cell culture. over the following 3 years, another two outbreaks occurred with low to high mortality in between asymptomatic periods. in the first 2 years, the same ranavirus was detected repeatedl ... | 2013 | 23535222 |
