Sporulation of Minchinia nelsoni (Haplosporida, Haplosporidiidae) in Crassostrea virginica (Gmelin).
Minchinia nelsoni, which Haskin, Stauber, and Mackin found in connective tissue and-digestive diverticula of the American oyster, is characterized by a distinct peripheral endosome in its plasmodial and spore nuclei and by spores of unique dimension (7.5 by 5.4 micro) This species is believed to be the etiologic agent, formerly reported as "MSX," responsible for extensive oyster mortalities along the Middle Atlantic Coast.
