Development of eNA Sampling for Early Detection of Pathogens in On‐Farm Water Sources

open access: yesEnvironmental DNA, Volume 8, Issue 2, March/April 2026.
We compare four water‐sampling methods for detecting microbial and viral eNA in livestock troughs and show all approaches effectively recover community profiles, supporting flexible, field‐ready surveillance of livestock pathogens. ABSTRACT Early detection of livestock pathogens is critical for mitigating risk and implementing timely control or ...

Characterization of a ranavirus inhibitor of the antiviral protein kinase PKR [PDF]

open access: yes, 2011
Background Ranaviruses (family Iridoviridae) are important pathogens of lower vertebrates. However, little is known about how they circumvent the immune response of their hosts.

Recovery of ranavirus dsDNA from formalin-fixed archival material [PDF]

open access: yesDiseases of Aquatic Organisms, 2000
The extraction and amplification of nucleic acid from formalin-fixed and paraffin-embedded tissues has become an important exercise in the collection of retrospective epidemiological data. A protocol is described that enables the extraction and amplification of dsDNA from fixed tissues within paraffin blocks and from specimens stored in 10% (aq ...

Widespread Detection of Amphibian Pathogens in Frog‐Biting Midges (Corethrellidae): Implications for Xenosurveillance

open access: yesBiotropica, Volume 58, Issue 2, March 2026.
Amphibian populations worldwide face threats from emerging infectious diseases. We screened frog‐biting midges (Corethrella spp.) from Central and South America for Batrachochytrium dendrobatidis, Ranaviruses, and Trypanosoma spp. using qPCR. All three pathogens were detected, indicating that Corethrella may act as vectors and represent promising tools

Distribution of a Non‐Native Amphibian in Britain Explained by a Complex History of Introductions and Translocations

open access: yesDiversity and Distributions, Volume 32, Issue 3, March 2026.
ABSTRACT Aim Success in a biological invasion often depends on whether the non‐native species can disperse from its introduction site and spread across the invaded landscape. The alpine newt, Ichthyosaura alpestris, has achieved a widespread distribution in Britain in the last century, with new records continuously reported. The objective of this study

ICTV Virus Taxonomy Profile: Iridoviridae [PDF]

open access: yes, 2017
The Iridoviridae is a family of large, icosahedral viruses with double-stranded DNA genomes ranging in size from 103 to 220 kbp. Members of the subfamily Alphairidovirinae infect ectothermic vertebrates (bony fish, amphibians and reptiles), whereas ...

Largemouth bass ranavirus: Current status and research progression

open access: yesAquaculture Reports, 2023
Largemouth bass ranavirus (LMBV) belongs to the Ranavirus genus of the Iridoviridae family and can infect numerous species of Percidae, such as largemouth bass (Micropterus salmoides), smallmouth bass (Micropterus dolomieu) and bluegill (Lepomis macrochirus).

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

open access: yesReviews 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 ...
