Description The present study forms the first report of Nematopsis sp. infection in the
edible oyster, Crassostrea madrasensis from India. The study was carried
out as part of a detailed pathological investigation of C. madrasensis
along the southwest coast of India. Sporozoites of Nematopsis sp. were
found in samples collected from two locations. Light microscopic
observation revealed ellipsoidal oocysts measuring 16.63±2.40 μm in
length and 11.11± 2.49 μm in width (n=30) in the connective tissues
of gills, mantle, visceral mass and gonads. Prevalence of infection
ranged from 11 to 27%. Apparent pathological changes included
compression of adjacent digestive diverticulae in visceral connective
tissue infections and presence of phagocytosed oocysts in water
channels in the case of gill infections. With relevance to the expanding
culture of C. madrasensis, monitoring potential pathogens of this species
in its natural habitat is important for developing suitable health
management packages.
