Herring Disease Program
Using an approach that involves a combination of field- and laboratory-based studies, we are investigating fish health factors that may be contributing to the failed recovery of Pacific herring populations in Prince William Sound, AK. Field studies are providing infection and disease prevalence data to inform the population models, serological data that indicate the prior exposure history and...

Detection of Nanophyetus salmincola in water, snails and fish tissues by quantitative PCR
The data are used to support the development and validation of two quantitative polymerase chain reaction (qPCR) assays to detect the parasite Nanophyetus salmincola DNA in water samples and fish and snail tissues. The data link to a series of experiments that are described in the publications. Experiment 1 defines the linearity and detection limits of the assays. Experiment 2 assesses the...
Exploration of the 2016 Yellowstone River fish kill and proliferative kidney disease in wild fish populations
Proliferative kidney disease (PKD) is an emerging disease that recently resulted in a large mortality event of salmonids in the Yellowstone River (Montana, USA). Total PKD fish mortalities in the Yellowstone River were estimated in the tens of thousands, which resulted in a multi‐week river closure and an estimated economic loss of US$500,000....

Nuclear inclusion X (NIX) is a gamma proteobacteria that infects the nuclei of gill epithelial cells in Pacific razor clams. NIX has been associated with clam die-offs in coastal Washington. A quantitative PCR (qPCR) assay was developed to detect NIX in Pacific razor clams, and assay specificity was confirmed by chromogenic in situ...
Travis, Brooke A; Batts, William N.; Groner, Maya; Hershberger, Paul; Fradkin, Steven C.; Conway, Carla M.; Park, Linda; Purcell, Maureen K.Disease in Central Valley salmon: Status and lessons from other systems
Chinook Salmon (Oncorhynchus tshawytscha) are increasingly vulnerable to anthropogenic activities and climate change, especially at their most southern species range in California’s Central Valley. There is considerable interest in understanding stressors that contribute to population decline and in identifying management actions that reduce the...

Piscine orthoreovirus (PRV-1) is a segmented RNA virus which is commonly found in salmonids in the Atlantic and Pacific Oceans. PRV-1 causes the Heart and Skeletal Muscle Inflammation (HSMI) disease in Atlantic salmon and is associated with several other disease conditions. Previous phylogenetic studies of genome segment 1 (S1) identified four...

Piscine orthoreovirus genotype 1 (PRV‐1) is the causative agent of heart and skeletal muscle inflammation (HSMI) in farmed Atlantic salmon (Salmo salar L.). The virus has also been found in Pacific salmonids in western North America, raising concerns about the risk to native salmon and trout. Here, we report the results of...

Hershberger, Paul; Purcell, Maureen K.Ichthyophonus sp. Infection in Opaleye (Girella nigricans)
Over a 3-year-period, 17 wild-caught opaleye (Girella nigricans) housed in a public display aquarium were found dead without premonitory signs. Grossly, 4 animals had pinpoint brown or black foci on coelomic adipose tissue. Histologically, liver, spleen, heart, and posterior kidney had mesomycetozoan granulomas in all cases; other organs were less...
LaDouceur, Elise E. B; St. Leger, Judy; Mena, Alexandria; Mackenzie, Ashley; Gregg, Jacob; Purcell, Maureen K.; Batts, William N.; Hershberger, PaulComplete genome sequences of the index isolates of two genotypes of Pacific salmon paramyxovirus
We report here the genome sequences of two index strains of Pacific salmon paramyxovirus isolated in 1982 and 1983 from adult salmon in Oregon. The isolates are most closely related to Atlantic salmon paramyxovirus, the type species of the genus Aquaparamyxovirus, but are sufficiently distinct to be considered two genotypes of a novel species.
Winton, James; Batts, William N.; Powers, Rachel L.; Purcell, Maureen K.Broad-spectrum antiviral JL122 blocks infection and inhibits transmission of aquatic rhabdoviruses
The aquaculture industry is growing rapidly to meet the needs for global protein consumption. Viral diseases in aquaculture are quite challenging due to lack of treatment options as well as limited injection-delivery vaccines, which are costly. Thus, water-immersion antiviral treatments are highly desirable. This study focused on broad-...

In response to reported findings of infectious salmon anaemia virus (ISAV) in British Columbia (BC), Canada, in 2011, U.S. national, state and tribal fisheries managers and fish health specialists developed and implemented a collaborative ISAV surveillance plan for the Pacific Northwest region of the United States. Accordingly, over a 3-1/2-year...
