Here, we report the simultaneous exploitation of entire communities of potential hosts with associated severe declines following invasion by a novel viral pathogen. We found two phylogenetically related, highly virulent viruses (genus Ranavirus, family Iridoviridae) causing mass mortality in multiple, diverse amphibian hosts in northern Spain, as well as a third, relatively avirulent virus. We document host declines in multiple species at multiple sites in the region. Our work reveals a group of pathogens that seem to have preexisting capacity to infect and evade immunity in multiple diverse and novel hosts, and that are exerting massive impacts on host communities. This report provides an exceptional record of host population trends being tracked in real time following emergence of a wildlife disease and a striking example of a novel, generalist pathogen repeatedly crossing the species barrier with catastrophic consequences at the level of host communities.

From fish to frogs and beyond: Impact and host range of emergent ranaviruses / Stephen J. Price in Virology, 511 (2017) 

Public Citation [article]  inVirology > 511 (2017) . - 272-279 Titre : From fish to frogs and beyond: Impact and host range of emergent ranaviruses Type de document : Imprimé Auteurs : Stephen J. Price ; Ellen Ariel ; Alicia Maclaine ; Gonçalo M. Rosa ; Maththew J. Gray ; Jesse L. Brunner ; Trenton W. J. Garner Année de publication : 2017 Article en page(s) : 272-279 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Lac d'altitude [CBNPMP-Thématique] Pollution de l'eau Résumé : Ranaviruses are pathogens of ectothermic vertebrates, including amphibians. We reviewed patterns of host range and virulence of ranaviruses in the context of virus genotype and postulate that patterns reflect significant variation in the historical and current host range of three groups of Ranavirus: FV3-like, CMTV-like and ATV-like ranaviruses. Our synthesis supports previous hypotheses about host range and jumps: FV3s are amphibian specialists, while ATVs are predominantly fish specialists that switched once to caudate amphibians. The most recent common ancestor of CMTV-like ranaviruses and FV3-like forms appears to have infected amphibians but CMTV-like ranaviruses may circulate in both amphibian and fish communities independently. While these hypotheses are speculative, we hope that ongoing efforts to describe ranavirus genetics, increased surveillance of host species and targeted experimental assays of susceptibility to infection and/or disease will facilitate better tests of the importance of hypothetical evolutionary drivers of ranavirus virulence and host range.
