Ranavirus Replication: Molecular, Cellular, and Immunological Events [PDF]

, 2015
The spatially compartmentalized replication strategy of ranaviruses and other members of the family Iridoviridae is unique among DNA viruses and is a hallmark of the family. Viral DNA replication initially takes place within the nucleus and results in the formation of genome-sized molecules.

In Vitro and In Vivo Toxicity and Antiviral Activity of Rhein Derivatives Against Nervous Necrosis Virus

Aquaculture, Fish and Fisheries, Volume 5, Issue 6, December 2025.
ABSTRACT Rhein has been demonstrated to exhibit antiviral activity against nervous necrosis virus (NNV). As rhein coexists in plants with various structurally analogous natural derivatives and may acquire improved biochemical properties through chemical modification, this study investigated the potential of several natural and synthetic derivatives for

The genome sequence of the emerging common midwife toad virus identifies an evolutionary intermediate within ranaviruses [PDF]

, 2012
Worldwide amphibian population declines have been ascribed to global warming, increasing pollution levels, and other factors directly related to human activities. These factors may additionally be favoring the emergence of novel pathogens.

Using environmental DNA for detection of Batrachochytrium salamandrivorans in natural water [PDF]

, 2020
Rapid, early, and reliable detection of invasive pathogenic microorganisms is essential in order to either predict or delineate an outbreak, and monitor appropriate mitigation measures. The chytrid fungus Batrachochytrium salamandrivorans is expanding in

Animal medical systems from Apis to apes: history, recent advances and future perspectives

Biological Reviews, Volume 100, Issue 6, Page 2608-2624, December 2025.
ABSTRACTAnimal medical systems encompass a wide range of behaviours aimed at maintaining or improving health. It has become clear that these behaviours are not limited to animals treating themselves (self‐medication) but also include the treatment of group members, resulting in the adoption of the more inclusive term “animal medication”. Behaviour with

Pathogenic fungus in feral populations of the invasive North American bullfrog in Argentina [PDF]

, 2017
Nearly a third (32.4%) of the world?s amphibian species are either threatened with extinction or already extinct (1). The chytrid fungus Batrachochytrium dendrobatidis (Bd) (Chytridiomycetes: Ryzophydiales) (2) has been recognized as responsible for mass

Mycoplasma agassizii Multilocus Sequence Typing Using Nanopore Sequencing: Insights Into Genetic Diversity and Isolate Characterization

Annals of the New York Academy of Sciences, Volume 1554, Issue 1, Page 153-162, December 2025.
ABSTRACT Mycoplasma agassizii (Mycoplasmopsis agassizii) is a major pathogen responsible for upper respiratory tract disease (URTD) in tortoises, contributing to worldwide population declines. Despite its significance, tools for strain‐level identification and epidemiological tracking remain limited.

Genomic Sequence of a Ranavirus Isolated from Pike-Perch Sander lucioperca [PDF]

, 2016
The pike-perch iridovirus (PPIV) was isolated in Finland from apparently healthy pike-perch fingerlings during routine disease surveillance. Our phylogenomic analysis revealed that PPIV is the first fish member of a clade of ranaviruses previously ...

An Early‐Life Disruption of Gut Microbiota Has Opposing Effects on Parasite Resistance in Two Host Species

Molecular Ecology, Volume 34, Issue 20, October 2025.
ABSTRACT Gut microbiota regulate multiple aspects of host health, including metabolism and the development of the immune system. However, we still know relatively little about how the gut microbiota influences host responses to parasitism in wild organisms, particularly whether host‐microbiota interactions contribute to variation in parasitism across ...

Comparative Genomics of Amphibian-like Ranaviruses, Nucleocytoplasmic Large DNA Viruses of Poikilotherms [PDF]

, 2016
Recent research on genome evolution of large DNA viruses has highlighted a number of incredibly dynamic processes that can facilitate rapid adaptation. The genomes of amphibian-like ranaviruses – double-stranded DNA viruses infecting amphibians, reptiles,
