Persistence of ranavirus in an East-Central Illinois amphibian community
… disease is one of their primary threats. Ranaviruses infect cold-blooded vertebrates, with FV3-like ranaviruses being associated with amphibian mortality events across much of North America. The frequency of these mortality events is unknown, due to difficulties in establishing and …

The presence of amphibian ranavirus in Virginia warm water fish hatchery ponds
… diseases, to travel over long distances. Ranavirus was previously found in two ponds at Harrison Lake National Fish Hatchery in Charles City County, Virginia. Therefore, the primary objective of this study was to determine if ranavirus is present in tadpoles from four warm water fish …

Characterizing the epidemiology of ranavirus in North American chelonians: diagnosis, surveillance, pathogenesis, and treatment
Ranaviruses have been proposed as a major threat to amphibian biodiversity, however the impact of these pathogens on reptiles is less well understood. In this dissertation, a quantitative PCR was developed that was 100% efficient in detecting the 54 bp segment of the major capsid protein of frog …

The Effects of Neuroendocrine Stress on Larval Development
… that chronic exposure to GC hormones increased ranavirus replication in infected wood frog larvae, but did not affect survival time. This could contribute to ranavirus epizootics. Acute GC hormone exposure increased survival, possibly by activing the inflammatory response. Finally, chapter four …

Modeling the health of free-living Illinois herptiles: an integrated approach incorporating environmental, physiologic, spatiotemporal, and pathogen factors
… significant larval mortality due to ranavirus (FV3). Poor health was best predicted by the additive effects of year, location, FV3 detection, and the presence of fresh traumatic injuries. FV3 is considered to represent a threat to silvery salamanders in Illinois, and recommendations …

Assessing the Impacts of Agricultural Land Use on Wood Frog (Lithobates sylvaticus) Presence and Health in Central Saskatchewan
… DNA (eDNA) to detect the presence of ranavirus and wood frogs. To assess the effects of these variables on both wood frog presence and health (condition, mass, and neutrophil to lymphocyte (N:L) ratios), I used boosted regression trees, a relatively novel but growing modelling …

Amphibian Community Composition And Disease Susceptibility In Ridge-Top Wetlands Of The Daniel Boone National Forest
… of either Batrachochytrium dendrobatidis (Bd) or ranavirus differs between natural and constructed wetlands of the London Ranger District, where construction methods, wetland density, and wetland placement differ from those in previous studies conducted in the Cumberland District. Seven natural …

Isolierung und Charakterisierung von Iridoviren
… of iridoviruses of lower vertebrates (genus Ranavirus), e.g., Rana esculenta Iridovirus and Frog virus 3. Restriction enzyme digests with the endonucleases MspI and HpaII indicated the lack of methylation of viral DNA. Polymerase chain reaction led to the amplification of a 420-bp gene …
