Detection of haplosporidian protistan parasites supports an increase to their known diversity, geographic range and bivalve host specificity
Abstract Haplosporidian protist parasites are a major concern for aquatic animal health, as they have been responsible for some of the most significant marine epizootics on record. Despite their impact on food security, aquaculture and ecosystem health, characterizing haplosporidian diversity, distr...
