Pathological effects of Urosporidium (Haplosporida) infection in microphallid metacercariae
Journal of Invertebrate Pathology, 1974Extensive pathological changes occur in Megalophallus metacercariae as a result of natural infections by the haplosporidan hyperparasite Urosporidium crescens. Infected and uninfected metaceriae, recovered from blue crabs from Chincoteague Bay, Maryland, were examined and compared histologically in regard to condition of metacercarial cyst wall ...

Sporulation of Minchinia nelsoni (Haplosporida: Haplosporidiidae) in Crassostrea virginica (Gmelin)
Science, 1966Minchinia 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 μ).

Science, 1966
Since 1957, oyster popuulations of the Middle Atlantic coast have been ravaged by a new sporozoan parasite that has been called "MSX." This parasite is identified as a new species of Minchinia that invades oysters through epithelial tissues of gill, palp, water tubes, and, occasionally, of the digestive tract ...

Haplosporidium simulii sp. n. is described. H. simulii infects larvae of the black fly Simulium venustum in Pennsylvania. A detailed comparison of the spore characteristics of H. simulii to the characteristics of spores of Haplosporidium tipulae from larval craneflies was made. Spores of H.

Uninucleate and binucleate cells and multinucleate plasmodia of a haplosporidan-like protist associated with heavy haemocytic infiltration were observed in histological sections of cockles, Cerastoderma edule, from the Ría de Noia (Galicia, NW Spain) in the course of a cockle health surveillance programme.

Fine structure of the oyster pathogen Minchinia nelsoni (Haplosporida, Haplosporidiidae)
Journal of Invertebrate Pathology, 1968Abstract The fine structure of plasmodia and spores of the sporozoan Michinia nelsoni , pathogenic to the oyster Crassostrea virginica , is described. Plasmodial nuclei have fibers of 150 to 180 A attached to centriolar plaques such as have been described for other microorganisms.
