Prevalence of Ranavirus Infection in Three Anuran Species across South Korea

Viruses, 2022
To cope with amphibian die-offs caused by ranavirus, it is important to know the underlying ranavirus prevalence in a region. We studied the ranavirus prevalence in tadpoles of two native and one introduced anuran species inhabiting agricultural and ...

Detecting mass mortality events in wildlife populations. [PDF]

Conserv Biol
Abstract Reports in the literature of mass mortality events (MMEs) involving diverse animal taxa are increasing. Yet, many likely go unobserved due to imperfect detection and infrequent sampling. MMEs involving small, cryptic species, for instance, can be difficult to detect even during the event, and degradation and scavenging of carcasses can make ...

Ranavirus: past, present and future [PDF]

Biology Letters, 2011
Emerging infectious diseases are a significant threat to global biodiversity. While historically overlooked, a group of iridoviruses in the genus Ranavirus has been responsible for die-offs in captive and wild amphibian, reptile and fish populations around the globe over the past two decades.

Influence of Herbicide Exposure and Ranavirus Infection on Growth and Survival of Juvenile Red-Eared Slider Turtles (Trachemys scripta elegans)

Viruses, 2021
Ranaviruses are an important wildlife pathogen of fish, amphibians, and reptiles. Previous studies have shown that susceptibility and severity of infection can vary with age, host species, virus strain, temperature, population density, and presence of ...

Ten years of ranavirus research (2010–2019): an analysis of global research trends

FACETS, 2021
Ranaviruses are large nucleocytoplasmic DNA viruses that infect ectothermic vertebrates. Here we report the results of a scientometric analysis of the field of ranavirology for the last 10 years.

Evidence for low prevalence of ranaviruses in Ontario, Canada’s freshwater turtle population [PDF]

PeerJ, 2019
Background Ontario, Canada is home to eight native species of turtles; all eight are federally listed as Species At Risk, due to anthropogenic threats. However, until recently, reports of infectious disease have been lacking.

Development and disease: how susceptibility to an emerging pathogen changes through anuran development. [PDF]

PLoS ONE, 2011
Ranaviruses have caused die-offs of amphibians across the globe. In North America, these pathogens cause more amphibian mortality events than any other pathogen.

High pathogen prevalence in an amphibian and reptile assemblage at a site with risk factors for dispersal in Galicia, Spain.

PLoS ONE, 2020
Ranaviruses are agents of disease, mortality and population declines in ectothermic vertebrates and emergences have been repeatedly linked to human activities. Ranaviruses in the common midwife toad ranavirus lineage are emerging in Europe.

Glutathione Impacts Both Batrachochytrium dendrobatidis Virulence and Amphibian Cellular Defense in a Chytridiomycosis Model. [PDF]

Microbiologyopen
Glutathione shapes interactions between Batrachochytrium dendrobatidis (Bd) and amphibian hosts. In Bd, glutathione reductase is essential for survival, and exogenous glutathione enhances zoospore release. In host cells, Bd infection depletes glutathione and increases oxidative stress.

Collapse of Amphibian Communities Due to an Introduced Ranavirus [PDF]

Current Biology, 2014
The emergence of infectious diseases with a broad host range can have a dramatic impact on entire communities and has become one of the main threats to biodiversity. Here, we report the simultaneous exploitation of entire communities of potential hosts with associated severe declines following invasion by a novel viral pathogen.
