Sphaerospora molnari is a microscopic endoparasite of carp (Cyprinus carpio) in pond cultures and natural freshwater habitats in Central and Eastern Europe.[1][2] In natural infections, S. molnari invades the epithelia of gills and surrounding skin regions. It then forms spores in between epithelial cells,[3] causing sphaerosporosis,[1] a pathological condition of the skin and gill tissues. Affected tissues show marked dystrophic changes and necrosis,[4][5][6] causing secondary bacterial infections and resulting in osmoregulatory and respiratory failure. Mortalities can reach 100%[6] but little is known about the overall distribution of the parasite species in European carp ponds or its economic impact on carp aquaculture.
