Complete genome analysis of a frog virus 3 (FV3) isolate and sequence comparison with isolates of differing levels of virulence [PDF]

Virology Journal, 2014
Frog virus 3 (FV3) is the type species of the genus Ranavirus, and in the past few decades, FV3 infections have resulted in considerable morbidity and mortality in a range of wild and cultivated amphibian species in the Americas, Europe, and Asia.

Negative effects of low dose atrazine exposure on the development of effective immunity to FV3 in Xenopus laevis [PDF]

Developmental and Comparative Immunology, 2014
The recent dramatic increase of the prevalence and range of amphibian host species and populations infected by ranaviruses such as Frog Virus 3 (FV3) raises concerns about the efficacies of amphibian antiviral immunity. In this context, the potential negative effects of water contaminants such as the herbicide atrazine, at environmentally relevant ...

Salt in the Wound: Assessing Pathogen Susceptibility in Amphibian Populations Across a Gradient of Salt Pollution. [PDF]

Ecol Evol
The survival function of nine larval wood frog populations and their viral loads when exposed to FV3. The populations were collected as eggs from a range of salt‐polluted ponds. Viral load data are means ±1 SE. The populations are ordered in terms of the saltiness of their natal ponds.

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.

Virus-Targeted Transcriptomic Analyses Implicate Ranaviral Interaction with Host Interferon Response in Frog Virus 3-Infected Frog Tissues

Viruses, 2021
Ranaviruses (Iridoviridae), including Frog Virus 3 (FV3), are large dsDNA viruses that cause devastating infections globally in amphibians, fish, and reptiles, and contribute to catastrophic amphibian declines.

On the Sensitivity of Hurricane Intensity and Structure to Horizontal Tracer Advection Schemes in FV3 [PDF]

Journal of the Atmospheric Sciences, 2021
AbstractWe investigate the sensitivity of hurricane intensity and structure to the horizontal tracer advection in the Geophysical Fluid Dynamics Laboratory (GFDL) Finite-Volume Cubed-Sphere Dynamical Core (FV3). We compare two schemes, a monotonic scheme and a less diffusive positive-definite scheme.

Targeted Transcriptomics of Frog Virus 3 in Infected Frog Tissues Reveal Non-Coding Regulatory Elements and microRNAs in the Ranaviral Genome and Their Potential Interaction with Host Immune Response

Frontiers in Immunology, 2021
BackgroundFrog Virus 3 (FV3) is a large dsDNA virus belonging to Ranaviruses of family Iridoviridae. Ranaviruses infect cold-blood vertebrates including amphibians, fish and reptiles, and contribute to catastrophic amphibian declines. FV3 has a genome at

Application and Evaluation of a NOAA GFS-Driven Air Quality Model Using CMAQv5.4 and High-Resolution Emissions: FIREX-AQ 2019. [PDF]

J Geophys Res Atmos
Abstract The National Air Quality Forecast Capability (NAQFC) provides numerical forecasting guidance of air quality up to 72 hr ahead over the United States. In this study, we evaluate the changes in its prediction skills by updating the Community Multiscale Air Quality (CMAQ) modeling system from version 5.3.1 to 5.4 and utilizing a high‐resolution 1‐

Amphibian (Xenopus laevis) Tadpoles and Adult Frogs Differ in Their Antiviral Responses to Intestinal Frog Virus 3 Infections

Frontiers in Immunology, 2021
The global amphibian declines are compounded by ranavirus infections such as Frog Virus 3 (FV3), and amphibian tadpoles more frequently succumb to these pathogens than adult animals.

TLR5-Mediated Reactivation of Quiescent Ranavirus FV3 in Xenopus Peritoneal Macrophages

Journal of Virology, 2021
This study in the amphibian Xenopus laevis provides new evidence of the critical role of macrophages in the persistence of ranaviruses in a quiescent state as well as in the reactivation of these pathogens into a virulent infection.
