- Abstract:
- ... A Ranavirus outbreak in a captive population of wild-caught individuals was monitored using clinical evaluations and real-time PCR in 317 wild box turtles held in captivity during translocation. During the 2-year study period, the population experienced 71.6% mortality, suggesting that ranaviruses can rapidly attenuate populations. Wide variation in infection rate (7–94% per sampling period) was o ...

- Abstract:
- ... Due to high-density aquafarming in Taiwan, groupers are commonly infected with two different iridoviruses: Megalocytivirus (grouper iridovirus of Taiwan, TGIV) and Ranavirus (grouper iridovirus, GIV). Iridoviral diseases cause mass mortality, and surviving fish retain these pathogens, which can then be horizontally transferred. These viruses have therefore become a major challenge for grouper aqua ...

- Abstract:
- ... Southern River terrapins (Batagur affinis) are among the most critically endangered turtles in the world. To augment the Cambodia population, a head-start program was established for the endemic subspecies Batagur affinis edwardmolli in 2006, and in 2015, prerelease health assessments were performed on 70 subadults (hatch years, 2006–2011). Combined choanal/cloacal swab samples (n = 70) were colle ...

- Abstract:
- ... Ranaviruses are important pathogens of amphibians, reptiles and fish. To meet the need for an analytical method for generating normalised and comparable infection data for these diverse host species, two standard-curve based quantitative-PCR (qPCR) assays were developed enabling viral load estimation across these host groups. A viral qPCR targeting the major capsid protein (MCP) gene was developed ...

- Abstract:
- ... Ranavirus has become a noticeable threat to both farmed and natural populations of fish and amphibians. Herein, we reported that 3 strains of novel viruses, designated as ScRIV-GM-20150902, CmRIV-XT-20150917 and ScRIV-ZS-20151201, were isolated from diseased Chinese perch and snakehead fish in China. Efficient propagation of these isolates were determined in Chinese perch brain (CPB) cell line by ...

BACKGROUND: An unusual mortality event in Johnstone River snapping turtles (Elseya irwini) in Far North Queensland, Australia, occurred during the summer months of December 2014 and January 2015. We report the data collected during the mortality event, including counts of sick and dead animals, clinical appearance and one necropsy. OUTBREAK DESCRIPTION: Moribund animals appeared lethargic with var ...

- Abstract:

Methods of disease risk analysis have been advocated to assess and mitigate these risks, and post‐release health and disease surveillance can be used to assess the effectiveness of the disease risk analysis, but results for a reintroduction programme have not to date been recorded. We carried out a disease risk anal ...

Affected fish exhibited extensive haemorrhage and ulceration on skin and muscle. Microscopically, the widespread haemorrhagic ulceration and necrosis were noted in gill, spleen and kidney with the presence of intracytoplasmic eosinophilic ...

- Abstract:
- ... Pathogens of wildlife can have direct impacts on human and livestock health as well as on biodiversity, as causative factors in population declines and extinctions. The World Organization for Animal Health (OIE) seeks to facilitate rapid sharing of information about animal diseases to enable up-to-date risk assessments of translocations of animals and animal products. The OIE also produces manuals ...

- Abstract:
- ... Coinfections are increasingly recognized as important drivers of disease dynamics. Consequently, greater emphasis has been placed on integrating principles from community ecology with disease ecology to understand within‐host interactions among parasites. Using larval amphibians and two amphibian parasites (ranaviruses and the trematode Echinoparyphium sp.), we examined the influence of coinfectio ...

- Abstract:
- ... A novel ranavirus with features similar to largemouth bass virus (LMBV) was isolated and then characterized from a natural mass mortality of adult hybrid mandarin (Siniperca scherzeri×Siniperca chuatsi). The isolated LMBV-like iridovirus was designated as mandarin ranavirus (MRV)-GD1301. The results of artificial infection showed that MRV-GD1301 was highly virulent to hybrid mandarin juveniles, an ...

- Abstract:
- ... Transmission 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., aggregate) or within groups, transmission may saturate. Mani ...

- Abstract:

Like all other vertebrate groups, amphibian responses to the environment are mediated through the brain (hypothalamic)-pituitary-adrenal/interrenal (HPA/I) axis and the sympathetic nervous system. Amphibians are facing historically unprecedented environmental stress due to climate change that will involve unpredictable temperature and rainfall regimes and possible nutritional deficits due to extre ...
