parasite Haplosporidium nelsoni (Ford & Haskin 1987) are both associated with massive oyster mortality in the United States.
In the 1970's outbreaks of QX disease caused by the haplosporidian
parasite Marteilia sydneyi (Perkins and Wolf, 1976) led to a further decline (Nell, 1993).

nelsoni occurs as a coinfection with another haplosporidian
parasite, Haplosporidium costale or seaside organism (Sunila et al.
The cluster split into two subgroups, the lesser group representing the Cape Fear River, Pamlico Sound (Bays 48-49), and the Chesapeake Bay mouth tended to have fewer cestodes, fewer ciliates in the alimentary canal, high haplosporidian
prevalence, and few Nematopsis relative to the sites in the larger subgroup (Delaware Bay to Savannah River in Fig.

parasite in O.
The planned fall 2007 planting was delayed because histological analysis of the seed (100 from each strain) prior to shipment found a previously unknown and rare haplosporidian
parasite, which was subsequently described (Ford et al.
parasite infections and a fatal neoplastic disorder were reported in Olympia oysters from Yaquina Bay and Alsea Bay, OR (Mix & Sprague 1974, Mix 1975).
