Ranavirus-associated mass mortality in wild amphibians, The Netherlands, 2010: A first report

Ranavirus-associated mass mortality in wild amphibians, The Netherlands, 2010: A first report In 2010, a mass die-off of over 1000 wild water frogs ( Pelophylax spp.) and at least 10 common newts ( Lissotriton vulgaris ) occurred in a pond in The Netherlands. Haemorrhagic disease with hepatomegaly and splenomegaly was evident. Microscopically, multiple organs presented cells with multifocal intracytoplasmic inclusion bodies, in which ranavirus-like particles were demonstrated ultrastructurally. All specimens examined tested positive for ranavirus by PCR. The sequence obtained showed a 100% identity with the one deposited for common midwife toad virus (CMTV). This is the first report of ranavirus-associated mortality in wild amphibian populations in The Netherlands. It is also the first time CMTV or a CMTV-like virus has been reported in these two species in the adult stage and outside of Spain. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png The Veterinary Journal Elsevier

Abstract

In 2010, a mass die-off of over 1000 wild water frogs ( Pelophylax spp.) and at least 10 common newts ( Lissotriton vulgaris ) occurred in a pond in The Netherlands. Haemorrhagic disease with hepatomegaly and splenomegaly was evident. Microscopically, multiple organs presented cells with multifocal intracytoplasmic inclusion bodies, in which ranavirus-like particles were demonstrated ultrastructurally. All specimens examined tested positive for ranavirus by PCR. The sequence obtained showed a 100% identity with the one deposited for common midwife toad virus (CMTV). This is the first report of ranavirus-associated mortality in wild amphibian populations in The Netherlands. It is also the first time CMTV or a CMTV-like virus has been reported in these two species in the adult stage and outside of Spain.
