The impetus for this research is to create a method that is both cost-effective and Introduction Sea star wasting disease (SSWD) describes a condition that has affected Asteroidea since at least 1898 [1] and is associated with periodic mass mortality, most recently as 2013-2014 [2].

Sea star-associated densovirus (SSaDV) belongs to the Parvoviridae family.Like the other members of its family, it is a single-stranded DNA virus.SSaDV has been suggested to be an etiological agent of sea star wasting disease, but conclusive evidence has not yet been obtained.

Densovirus associated with sea-star wasting disease and mass mortality. The etiology of sea star wasting syndrome is hypothesized to be caused by a densovirus, sea star-associated densovirus (SSaDV), that has previously been reported on the Pacific and Atlantic Coasts of the United States.

Densovirus associated with sea-star wasting disease and mass mortality (Nov 17, 2014) Effects of temperature, season and locality on wasting disease in the keystone predatory sea star Pisaster ochraceus (Nov 9, 2009) Sea Star Disease and Population Declines at the Channel Isalnds (1999) advanced search: by author, subreddit... this post was submitted on 18 Nov 2014. 2014; 111(48):17278-83 (ISSN: 1091-6490). This last year, my thesis research has explored the possibility of developing a method that could successfully implement Scanning Electron Microscopy to identify sea star-associated densoviurs in purple-orange ochre sea stars (Pisaster ochraceus) infected with sea star wasting disease. In this paper, we present evidence that the cause of the disease is transmissible from disease-affected animals to apparently healthy individuals, that the disease-causing agent is a virus-sized microorganism, and that the best candidate viral taxon, the sea star-associated densovirus (SSaDV), is in greater abundance in diseased than in healthy sea stars. Populations of at least 20 asteroid species on the Northeast Pacific Coast have recently experienced an extensive outbreak of sea-star (asteroid) wasting disease (SSWD). Densovirus associated with sea-star wasting disease mass mortality. In 2013, a range-wide sea star wasting disease (SSWD) outbreak leading to mass mortality across the range of Pisaster ochraceus created a rare opportunity to explore the genetic landscape in which selection acts, and to identify alleles that responded directly to the event through changes in frequency. Invert Survival J. doi: 10.1073/pnas.1416625111. We assessed the impacts of sea star wasting disease in the Salish Sea, a Canadian / United States transboundary marine ecosystem, and world-wide hotspot for temperate asteroid species diversity with a high degree of endemism. 48, p. 17278.
