Heterogeneities in the infection process drive ranavirus transmission

Ecology, 2017
AbstractTransmission is central to our understanding and efforts to control the spread of infectious diseases. Because transmission generally requires close contact, host movements and behaviors can shape transmission dynamics: random and complete mixing leads to the classic density‐dependent model, but if hosts primarily interact locally (e.g ...

Viral Disease Histopathology in Aquaculture Finfish: Organ‐Specific Pathological Changes and Diagnostic Insights, Referencing the World Organisation for Animal Health: A Review

Reviews in Aquaculture, Volume 18, Issue 2, March 2026.
ABSTRACT The aquaculture industry faces significant challenges from viral diseases, many of which are listed by the World Organisation for Animal Health (WOAH) as priority pathogens due to their impact on global finfish health and production. This review synthesizes current knowledge on the histopathology of key WOAH‐listed viral pathogens, including ...

Lack of molecular detection of frog virus 3-like ranavirus (FV3) in mosquitoes during natural outbreak and nonoutbreak conditions

FACETS, 2020
Ranaviruses are worldwide pathogens of ectothermic vertebrates that can threaten herptile conservation efforts. Identifying transmission routes is critical for understanding disease ecology and promoting species conservation.

Juvenile agile frogs spatially avoid ranavirus-infected conspecifics. [PDF]

Sci Rep
Exposure to contagious pathogens can result in behavioural changes, which can alter the spread of infectious diseases. Healthy individuals can express generalized social distancing or avoid the sources of infection, while infected individuals can show passive or active self-isolation. Amphibians are globally threatened by contagious diseases, yet their

A broadly applicable method to characterize large DNA viruses and adenoviruses based on the DNA polymerase gene [PDF]

, 2006
Background Many viral pathogens are poorly characterized, are difficult to culture or reagents are lacking for confirmatory diagnoses. We have developed and tested a robust assay for detecting and characterizing large DNA viruses and adenoviruses.

Evolution of research on global amphibian declines

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract In the late 1980s, the scientific community became aware of severe, enigmatic amphibian population declines. These declines triggered a wave of research focused on quantifying their extent and identifying key drivers. We used text‐analysis techniques, including topic modeling and geoparsing, to examine the evolution of research focused on ...

The Molecular Biology of Frog Virus 3 and other Iridoviruses Infecting Cold-Blooded Vertebrates

Viruses, 2011
Frog virus 3 (FV3) is the best characterized member of the family Iridoviridae. FV3 study has provided insights into the replication of other family members, and has served as a model of viral transcription, genome replication, and virus-mediated host ...

Replication and transcription machinery for ranaviruses: components, correlation, and functional architecture

Cell & Bioscience, 2022
Background Ranaviruses (family Iridoviridae) are promiscuous pathogens that can infect across species barriers in poikilotherms and can replicate in amphibian and fish cells and even in cultured mammalian cells.

An analysis of the linked decisions in the confiscation of illegally traded turtles

Conservation Science and Practice, Volume 8, Issue 2, February 2026.
Increased enforcement of laws governing the international trade of freshwater turtles is increasing the numbers of confiscated turtles. Decision makers are thus increasingly faced with a complex decision, involving multiple linked agencies, regarding the disposition of turtles of unknown origin and disease status, which creates uncertainty about the ...
